VXLAN commands

The S6861 switch series does not support EVPN.

VXLAN-DCI is not supported by the S6861 switch series and S6800 switches labeled with the following product codes:

·     LS-6800-2C.

·     LS-6800-32Q.

·     LS-6800-4C.

Basic VXLAN commands

ac statistics enable

Use ac statistics enable to enable packet statistics for Ethernet service instances of a VLAN.

Use undo ac statistics enable to disable packet statistics for Ethernet service instances of a VLAN.

Syntax

ac statistics enable

undo ac statistics enable

Default

The packet statistics feature is disabled for Ethernet service instances of a VLAN.

Views

VLAN view

Predefined user roles

network-admin

Usage guidelines

This command enables packet statistics for the Ethernet service instances automatically created for VLAN-based VXLAN assignment.

Before you enable this feature, you must use the vxlan vlan-based command to enable VLAN-based VXLAN assignment.

Examples

# Map VLAN 10 to VXLAN 100, and enable packet statistics for Ethernet service instances of VLAN 10.

<Sysname> system-view

[Sysname] vxlan vlan-based

[Sysname] vlan 10

[Sysname-vlan10] vxlan vni 100

[Sysname-vlan10] ac statistics enable

Related commands

display l2vpn service-instance

reset l2vpn statistics ac

vxlan vlan-based

arp suppression enable

Use arp suppression enable to enable ARP flood suppression.

Use undo arp suppression enable to disable ARP flood suppression.

Syntax

arp suppression enable

undo arp suppression enable

Default

ARP flood suppression is disabled.

Views

VSI view

Predefined user roles

network-admin

Usage guidelines

ARP flood suppression reduces ARP request broadcasts by enabling the VTEP to reply to ARP requests on behalf of VMs.

This feature snoops ARP packets to populate the ARP flood suppression table with local and remote MAC addresses. If an ARP request has a matching entry, the VTEP replies to the request on behalf of the VM. If no match is found, the VTEP floods the request to both local and remote sites.

Examples

# Enable ARP flood suppression for VSI vsi1.

<Sysname> system-view

[Sysname] vsi vsi1

[Sysname-vsi-vsi1] arp suppression enable

Related commands

display arp suppression vsi

reset arp suppression vsi

bandwidth (Ethernet service instance view)

Use bandwidth to set the bandwidth limit for an Ethernet service instance.

Use undo bandwidth to restore the default.

Syntax

bandwidth bandwidth

undo bandwidth

Default

No bandwidth limit is set for an Ethernet service instance.

Views

Ethernet service instance view

Predefined user roles

network-admin

Parameters

bandwidth: Specifies a bandwidth limit in kbps. The value range for this argument is 64 to 167772159.

Usage guidelines

The bandwidth limit takes effect only on incoming traffic. An Ethernet service instance drops excess incoming traffic when its bandwidth limit is reached.

If you use the bandwidth command for both an Ethernet service instance and its mapped VSI, the Ethernet service instance bandwidth is limited exclusively from the VSI bandwidth. For example, VSI vsi1 has AC 1, AC 2, AC 3, and Tunnel 1. The bandwidth limit of VSI vsi1 is 500 kbps, and the bandwidth limit of AC 1 is 120 kbps. The total bandwidth of AC 2, AC 3, and Tunnel 1 is limited to 500 kbps.

Examples

# Set the bandwidth limit to 10240 kbps for Ethernet service instance 200.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1

[Sysname-Ten-GigabitEthernet1/0/1] service-instance 200

[Sysname-Ten-GigabitEthernet1/0/1-srv200] encapsulation s-vid 200

[Sysname-Ten-GigabitEthernet1/0/1-srv200] bandwidth 10240

Related commands

bandwidth (VSI view)

bandwidth (VSI view)

Use bandwidth to set the bandwidth limit for a VSI.

Use undo bandwidth to restore the default.

Syntax

bandwidth bandwidth

undo bandwidth

Default

No bandwidth limit is set for a VSI.

Views

VSI view

Predefined user roles

network-admin

Parameters

bandwidth: Specifies a bandwidth limit in kbps. The value range for this argument is 64 to 167772159.

Usage guidelines

This command limits the total bandwidth of the incoming traffic on all ACs and VXLAN tunnels mapped to a VSI. A VSI drops excess incoming traffic when its bandwidth limit is reached.

If you use the bandwidth command for both an Ethernet service instance and its mapped VSI, the Ethernet service instance bandwidth is limited exclusively from the VSI bandwidth. For example, VSI vsi1 has AC 1, AC 2, AC 3, and Tunnel 1. The bandwidth limit of VSI vsi1 is 500 kbps, and the bandwidth limit of AC 1 is 120 kbps. The total bandwidth of AC 2, AC 3, and Tunnel 1 is limited to 500 kbps.

If you use both the restrain and bandwidth commands on a VSI, the bandwidth command limits only the bandwidth of the traffic not restrained by the restrain command.

Examples

# Set the bandwidth limit to 10240 kbps for VSI vpn1.

<Sysname> system-view

[Sysname] vsi vpn1

[Sysname-vsi-vpn1] bandwidth 10240

Related commands

Parameters

-c count: Specifies the number of ICMP echo requests to be sent. The value range is 1 to 4294967295, and the default value is 5.

-m interval: Specifies the interval for sending ICMP echo requests. The value range is 1 to 65535 milliseconds, and the default value is 200 milliseconds.

-s packet-size: Specifies the length of ICMP echo quests (IP and ICMP headers not included). The value range is 20 to 8100 bytes, and the default value is 56 bytes.

-t time-out: Specifies the ICMP echo reply timeout period. The value range is 0 to 65535 milliseconds, and the default value is 2000 milliseconds. If the device does not receive an ICMP echo reply within the timeout period after sending an ICMP echo request, the device determines that the ICMP echo reply times out.

vxlan-id vxlan-id: Specifies a VXLAN ID. The value range for the vxlan-id argument is 0 to 16777215.

source-mac mac-address: Specifies the source MAC address of ICMP echo requests. The MAC address must be a local VM address in the MAC address table of the specified VXLAN.

destination-mac mac-address: Specifies the destination MAC address of ICMP echo requests. The MAC address must be a remote VM address in the MAC address table of the specified VXLAN.

Usage guidelines

Before you use this command, execute the emulate-ping vxlan enable command to enable the remote VM reachability test feature.

The emulate-ping vxlan command enables the device to test the reachability of a remote VM by simulating a local VM to send ICMP echo requests. The requests are encapsulated in Layer 2 data frames and then sent to the remote VM in the specified VXLAN. The device determines the reachability of the remote VM based on the response time and number of received ICMP echo replies. You can view the packet transmission statistics in the command output.

The emulate-ping vxlan command is not supported if EVPN distributed relay is configured on the device. For more information about EVPN distributed relay, see EVPN Configuration Guide.

Predefined user roles

network-admin

Parameters

s-vid: Matches frames that are tagged with the specified outer 802.1Q VLAN IDs.

c-vid: Matches frames that are tagged with the specified inner 802.1Q VLAN IDs.

vlan-id: Specifies an 802.1Q VLAN ID in the range of 1 to 4094.

vlan-id-list: Specifies a space-separated list of up to eight VLAN items. Each item specifies a VLAN ID or a range of VLAN IDs in the format of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. If you specify this option following the s-vid keyword, you can specify a maximum of eight VLAN items. If you specify this option following the c-vid keyword, you can specify only one VLAN item.

only-tagged: Matches tagged frames. If the outer 802.1Q VLAN is not the PVID, the matching result does not differ, whether or not you specify the only-tagged keyword. If the outer 802.1Q VLAN is the PVID, the matching result depends on whether or not the only-tagged keyword is specified.

·     To match only PVID-tagged frames, specify the only-tagged keyword.

·     To match both untagged frames and PVID-tagged frames, do not specify the only-tagged keyword.

all: Specifies all 802.1Q VLAN IDs.

default: Specifies the default match criterion. On an interface, you can configure this criterion only in one Ethernet service instance. The device matches frames with the frame match criteria (including the default criterion) in the Ethernet service instances on the interface in the order as described in the usage guidelines. The Ethernet service instance that uses the default match criterion matches any frames if it is the only instance on the interface.

tagged: Matches any frames that have an 802.1Q VLAN tag.

untagged: Matches any frames that do not have an 802.1Q VLAN tag.

Usage guidelines

The encapsulation s-vid vlan-id [ only-tagged ] and encapsulation s-vid vlan-id c-vid vlan-id commands can specify the same outer VLAN ID for two Ethernet service instances on an interface. Frames that match both Ethernet service instances are assigned to the Ethernet service instance configured by using the encapsulation s-vid vlan-id c-vid vlan-id command.

When you configure the encapsulation default command for an Ethernet service instance on a Layer 2 Ethernet interface or Layer 2 aggregate interface, follow these restrictions:

·     If the Ethernet service instance uses the VLAN access mode, the device uses the following order to match frames on the interface to an Ethernet service instance:

a.     encapsulation { tagged | untagged }.

b.     encapsulation default.

c.     encapsulation s-vid vlan-id [ c-vid { vlan-id-list | all } | only-tagged ] or encapsulation s-vid vlan-id-list [ c-vid vlan-id-list ].

·     If the Ethernet service instance uses the Ethernet access mode, the device uses the following order to match frames on the interface to an Ethernet service instance:

a.     encapsulation s-vid vlan-id [ c-vid { vlan-id-list | all } | only-tagged ] or encapsulation s-vid vlan-id-list [ c-vid vlan-id-list ].

b.     encapsulation { tagged | untagged }.

c.     encapsulation default.

An Ethernet service instance can contain only one frame match criterion. To change the frame match criterion, first execute the undo encapsulation command to remove the original criterion. When you remove the frame match criterion in an Ethernet service instance, the mapping between the service instance and the VSI is removed automatically.

On an SDN network, after you change the matching outer VLAN ID on the VTEP, you must modify the VLAN ID that the controller issues in the Set-Field action for configuration consistency.

Examples

# Configure Ethernet service instance 1 on Ten-GigabitEthernet 1/0/1 to match frames that have an outer 802.1Q VLAN ID of 111.

Parameters

all: Specifies broadcast, unknown unicast, and unknown multicast traffic.

broadcast: Specifies broadcast traffic.

unknown-multicast: Specifies unknown multicast traffic.

unknown-unicast: Specifies unknown unicast traffic.

all-direction: Disables flooding traffic received from an AC or VXLAN tunnel interface to any other ACs and VXLAN tunnel interfaces of the same VSI. If you do not specify this keyword, the command only disables flooding traffic received from ACs to VXLAN tunnel interfaces of the VSI.

dci: Disables flooding only to VXLAN-DCI tunnel interfaces. If you do not specify this keyword, the command disables flooding to both VXLAN tunnel interfaces and VXLAN-DCI tunnel interfaces.

 

NOTE:

The dci keyword is not supported by the S6861 switch series and S6800 switches labeled with the following product codes:

·     LS-6800-2C.

·     LS-6800-32Q.

·     LS-6800-4C.

Usage guidelines

By default, the device floods broadcast, unknown unicast, and unknown multicast frames received from the local site to the following interfaces in the frame's VXLAN:

·     All site-facing interfaces except for the incoming interface.

·     All VXLAN tunnel interfaces.

When receiving broadcast, unknown unicast, and unknown multicast frames on VXLAN tunnel interfaces, the device floods the frames to all site-facing interfaces in the frames' VXLAN.

To confine a kind of flood traffic, use this command to disable flooding for that kind of flood traffic on the VSI bound to the VXLAN.

If VXLAN-DCI is configured, flood traffic is also sent out of VXLAN-DCI tunnel interfaces. To confine flood traffic to the site-facing interfaces and VXLAN tunnels within a data center, you can specify the dci keyword to disable flooding only to VXLAN-DCI tunnel interfaces.

The all-direction keyword disables flooding traffic received from an AC or VXLAN tunnel interface to any other ACs and VXLAN tunnel interfaces of the same VSI. If VXLAN-DCI is configured, this keyword also disables flooding between VXLAN tunnel interfaces and VXLAN-DCI tunnel interfaces.

Use undo group to restore the default.

Syntax

group group-address source source-address

Default

A VXLAN uses unicast mode (head-end replication) for flood traffic. No multicast group address or source IP address is specified for multicast VXLAN packets.

Views

VXLAN view

Predefined user roles

network-admin

Parameters

group-address: Specifies a multicast address in the range of 224.0.1.0 to 239.255.255.255.

source source-address: Specifies a source IP address for multicast VXLAN packets.

Usage guidelines

To reduce traffic sent to the transport network, use multicast mode if the network has dense flood traffic or many VTEPs.

The multicast mode supports the following multicast methods:

·     PIM—VTEPs and transport network devices run PIM to generate multicast forwarding entries. On a VTEP, you can use the IP address of a loopback interface as the source IP address for multicast VXLAN packets. If the VTEP has multiple transport-facing interfaces, PIM dynamically selects the outgoing interfaces for multicast VXLAN packets.

·     IGMP host—VTEPs and transport network devices run PIM and IGMP to generate multicast forwarding entries.

¡     Transport-facing interfaces of VTEPs act as IGMP hosts.

¡     Transport network devices connected to a VTEP run IGMP.

¡     All transport network devices run PIM.

On a VTEP, you must use the IP address of the transport-facing interface as the source IP address for multicast VXLAN packets. If the VTEP has multiple transport-facing interfaces, multicast VXLAN packets are sent to the transport network through the interface that provides the source IP address for multicast VXLAN packets.

VTEPs in a multicast-mode VXLAN can use different multicast methods.

To forward multicast traffic correctly, you must use the source IP address of an up VXLAN tunnel as the source IP address for multicast VXLAN packets.

For multicast-mode VXLANs, transport network devices must maintain multicast group and forwarding information. To reduce the multicast forwarding entries maintained by transport network devices, assign a multicast group address to multiple VXLANs. The VTEP separates traffic between VXLANs by VXLAN IDs.

 

 

NOTE:

For VXLANs that use the same multicast group address, you must configure the same source IP address for their multicast VXLAN packets.

 

If you execute the group command multiple times for a VXLAN, the most recent configuration takes effect.

Examples

# Set the multicast group address to 233.1.1.1 for flood traffic in VXLAN 100. Set the source IP address to 2.1.1.1 for multicast VXLAN packets.

<Sysname> system-view

[Sysname] vsi aaa

Usage guidelines

ND flood suppression reduces ND request multicasts by enabling the VTEP to reply to ND requests on behalf of user terminals.

This feature snoops ND packets to populate the ND flood suppression table with local and remote MAC addresses. If an ND request has a matching entry, the VTEP replies to the request on behalf of the user terminal. If no match is found, the VTEP floods the request to both local and remote sites.

Predefined user roles

network-admin

Usage guidelines

This command is applicable to SDN networks.

To reduce broadcast traffic in an SDN network, the controller synchronizes the MAC addresses that each VTEP learns among all VTEPs. On a VTEP, an interface can learn MAC addresses in hardware or software.

·     In hardware-based learning mode, the software periodically obtains new MAC addresses from the hardware and advertises the MAC addresses to the controller.

·     In software-based learning mode, the software instantly issues new MAC addresses to the hardware and the controller as soon as they are learned.

Software-based MAC learning shortens the interval at which the VTEP advertises MAC address reachability information to the controller. However, this mode is resource intensive. When you use this mode, you must fully understand its impact on the device performance.

Examples

# Enable software-based MAC learning on Ten-GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1

[Sysname-Ten-GigabitEthernet1/0/1] l2vpn mac-address software-learning enable

learning mode disable

network-admin

Usage guidelines

When you enable MAC address learning on an Ethernet service instance, make sure MAC address learning is enabled on the VSI to which the Ethernet service instance is mapped. To enable MAC address learning for a VSI, use the mac-learning enable command.

When MAC address learning is disabled on an Ethernet service instance, it can use only the static local-MAC address entries added by using the mac-address static command.

Examples

# Disable MAC address learning on Ethernet service instance 200.

<Sysname> system-view

[Sysname] vsi vpn1

[Sysname-vsi-vpn1] mac-learning enable

[Sysname-vsi-vpn1] quit

mac-address mac-learning priority

Use mac-address mac-learning priority to set the MAC learning priority of an Ethernet service instance.

Use undo mac-address mac-learning priority to restore the default.

Syntax

Views

Ethernet service instance view

Predefined user roles

network-admin

Parameters

high: Specifies high MAC learning priority.

low: Specifies low MAC learning priority.

Usage guidelines

This setting takes effect only after the Ethernet service instance is mapped to a VSI.

A VSI uses the MAC learning priority to control MAC address learning of its Ethernet service instances. An Ethernet service instance with high MAC learning priority takes precedence over an Ethernet service instance with low MAC learning priority when they learn the same MAC address. For example:

·     A MAC address entry of a high-priority Ethernet service instance can be overwritten only when the MAC address is learned on another high-priority Ethernet service instance.

·     A MAC address entry of a low-priority Ethernet service instance is overwritten when the MAC address is learned on a high-priority Ethernet service instance or another low-priority Ethernet service instance.

Examples

# Set the MAC learning priority to high for Ethernet service instance 1 on Ten-GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1

undo mac-address static [ mac-address ] [ interface interface-type interface-number service-instance instance-id | interface tunnel tunnel-number ] vsi vsi-name

Default

Predefined user roles

network-admin

Parameters

mac-address: Specifies a MAC address in H-H-H format. Do not specify a multicast MAC address or an all-zeros MAC address. You can omit the consecutive zeros at the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001.

interface interface-type interface-number service-instance instance-id: Specifies an Ethernet service instance on an interface. The interface-type interface-number argument specifies the interface by its type and number. The instance-id argument specifies the Ethernet service instance by its ID in the range of 1 to 4096. This option applies to local MAC addresses.

interface tunnel tunnel-number: Specifies a VXLAN or VXLAN-DCI tunnel interface by its tunnel interface number. The specified tunnel interface must already exist. This option applies to remote MAC addresses.

vsi vsi-name: Specifies a VSI name, a case-sensitive string of 1 to 31 characters.

Usage guidelines

A local MAC address is the MAC address of a VM in the local site. Local MAC entries include manually added entries and dynamically learned entries.

A remote MAC address is the MAC address of a VM in a remote site. Remote MAC entries include manually added MAC entries, dynamically learned MAC entries, and MAC entries advertised through BGP EVPN.

When you add a local MAC address entry, make sure the specified Ethernet service instance has been mapped to the VSI. When you add a remote MAC address entry, make sure the VSI's VXLAN has been specified on the VXLAN or VXLAN-DCI tunnel.

Do not configure static remote-MAC entries for tunnels that are automatically established by using EVPN.

·     EVPN re-establishes tunnels if the transport-facing interface goes down and then comes up. If you have configured static remote-MAC entries, the entries are deleted when the tunnels are re-established.

·     EVPN re-establishes tunnels if you perform configuration rollback. If the tunnel IDs change during tunnel re-establishment, configuration rollback fails, and static remote-MAC entries on the tunnels cannot be restored.

The undo mac-address static vsi vsi-name command removes all static MAC address entries for a VSI.

Examples

# Add MAC address 000f-e201-0101 to VSI vsi1. Specify Tunnel-interface 1 as the outgoing interface.

<Sysname> system-view

Predefined user roles

network-admin

Usage guidelines

The 802.1X or MAC authentication feature can use the authorization VSI, the guest VSI, the Auth-Fail VSI, and the critical VSI to control the access of users to network resources. When assigning a user to a VSI, 802.1X or MAC authentication sends the VXLAN feature the VSI information and the user's access information, including access interface, VLAN, and MAC address. Then the VXLAN feature creates a dynamic Ethernet service instance for the user and maps it to the VSI.

A dynamic Ethernet service instance supports the following traffic match modes:

·     VLAN-based mode—Matches frames by VLAN ID.

·     MAC-based mode—Matches frames by VLAN ID and source MAC address.

To use MAC-based traffic match mode for dynamic Ethernet service instances, you must enable MAC authentication or 802.1X authentication that uses MAC-based access control.

This command takes effect only on dynamic Ethernet service instances. Static Ethernet service instances created by using the service-instance command match traffic only by the VLAN IDs specified by using the encapsulation command.

You cannot change the traffic match mode when dynamic Ethernet service instances already exist on an interface.

Examples

# Enable MAC-based traffic match mode for dynamic Ethernet service instances on Ten-GigabitEthernet 1/0/1.

Parameters

broadcast: Specifies the broadcast restraint bandwidth.

multicast: Specifies the multicast restraint bandwidth.

unknown-unicast: Specifies the unknown unicast restraint bandwidth. Unknown unicast packets refer to the unicast packets whose destination MAC addresses are not in the MAC address table of the VSI.

bandwidth: Specifies the broadcast, multicast, or unknown unicast restraint bandwidth in kbps. The value for this argument can be 0 or in the range of 64 to 167772159. If you set this argument to 0, the command disables the specified kind of flood traffic.

Usage guidelines

When the bandwidth of incoming broadcast, multicast, or unknown unicast traffic on VXLAN tunnels of a VSI exceeds the configured restraint bandwidth, the VSI drops the exceeding traffic.

If you use both the restrain and bandwidth commands on a VSI, the bandwidth command limits only the bandwidth of the traffic not restrained by the restrain command.

If you use both the restrain and selective-flooding mac-address commands on a VSI, the restrain command limits only the bandwidth of the traffic not enabled with selective flood.

Parameters

tunnel-number: Specifies a tunnel interface number. The tunnel must be an existing VXLAN tunnel.

backup-tunnel tunnel-number: Specifies a backup tunnel by its tunnel interface number. The tunnel must be an existing VXLAN tunnel.

flooding-proxy: Enables flood proxy on the tunnel for the VTEP to send flood traffic to the flood proxy server. The flood proxy server replicates and forwards flood traffic to remote VTEPs. If you do not specify this keyword, flood proxy is disabled on the tunnel.

all: Specifies all VXLAN tunnels.

Usage guidelines

This command assigns a VXLAN tunnel to a VXLAN to provide Layer 2 connectivity for the VXLAN between two sites. In unicast mode, the system floods unknown unicast, multicast, and broadcast traffic to each tunnel in the VXLAN.

You can assign multiple VXLAN tunnels to a VXLAN, and configure a VXLAN tunnel to trunk multiple VXLANs.

To assign a pair of primary and backup VXLAN tunnels to the VXLAN, specify the backup-tunnel tunnel-number option. When the primary VXLAN tunnel is operating correctly, the backup VXLAN tunnel does not forward traffic. When the primary VXLAN tunnel goes down, traffic is switched to the backup VXLAN tunnel.

On a VSI, you can enable flood proxy on multiple VXLAN tunnels. The first tunnel that is enabled with flood proxy works as the primary proxy tunnel to forward broadcast, multicast, and unknown unicast traffic. Other proxy tunnels are backups that do not forward traffic when the primary proxy tunnel is operating correctly.

To change a flood proxy tunnel for a VXLAN, perform the following tasks:

·     Use the undo tunnel command to remove the flood proxy tunnel.

·     Use the tunnel command to enable flood proxy on another tunnel and assign the tunnel to the VXLAN.

You cannot use the tunnel all command for VXLAN-DCI tunnel assignment. Please assign VXLAN-DCI tunnels to a VXLAN one by one.

If you assign VXLAN tunnels to a VXLAN one by one, you cannot remove all the VXLAN tunnels by using the undo tunnel all command.

If you assign all VXLAN tunnels to a VXLAN by using the tunnel all command, you cannot remove the VXLAN tunnels one by one. You can only use the undo tunnel all command to remove all the VXLAN tunnels.

As a best practice, use the tunnel all command only when batch VXLAN tunnel assignment is necessary.

Examples

# Assign VXLAN tunnels 1 and 2 to VXLAN 10000.

<Sysname> system-view

[Sysname] vsi vpna

[Sysname-vsi-vpna] vxlan 10000

Default

BFD is disabled on a VXLAN tunnel interface.

Views

VXLAN tunnel interface view

Predefined user roles

network-admin

Parameters

destination-mac mac-address: Specifies a destination MAC address in H-H-H format for BFD control packets. The MAC address must be a remote VTEP address or a multicast address. You can omit the consecutive zeros at the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001.

Usage guidelines

Enable BFD on both ends of a VXLAN tunnel for quick link connectivity detection. The VTEPs periodically send BFD single-hop control packets to each other through the VXLAN tunnel. A VTEP sets the tunnel state to Defect if it has not received control packets from the remote end for 5 seconds. In this situation, the tunnel interface state is still Up. The tunnel state will change from Defect to Up if the VTEP can receive BFD control packets again.

For BFD sessions to come up, you must reserve a VXLAN by using the reserved vxlan command.

Do not use BFD together with uRPF. When uRPF is enabled, BFD sessions cannot come up. For more information about uRPF, see Security Configuration Guide.

Examples

# Enable BFD on VXLAN tunnel interface Tunnel 9, and specify 1-1-1 as the destination MAC address for BFD control packets.

Views

System view

Predefined user roles

network-admin

Parameters

source interface interface-type interface-number: Specifies an interface by its type and number.

Usage guidelines

If a VXLAN tunnel is configured on only one VTEP of a pair of VTEPs, the VXLAN tunnel is a unidirectional tunnel to the VTEP not configured with the tunnel. In this situation, that VTEP drops the VXLAN packets received from the unidirectional VXLAN tunnel. For a VTEP to receive VXLAN packets from a unidirectional VXLAN tunnel, enable default VXLAN decapsulation on the interface whose IP address is the tunnel destination address. The VTEP will decapsulate all the VXLAN packets destined for the IP address of that interface.

This command takes effect only when the specified interface has an IP address.

The IP address of the specified interface must meet the following requirements:

·     It is the destination address of a unidirectional VXLAN tunnel.

·     It is the source address of a minimum of one up VXLAN tunnel.

Default VXLAN decapsulation does not take effect on bidirectional VXLAN tunnels. If you remove the one-way communication issue for a VXLAN tunnel by configuring the tunnel on both the local and remote VTEPs, this feature no longer takes effect on that tunnel.

Examples

# Enable default VXLAN decapsulation.

Usage guidelines

You can assign customer traffic to a VXLAN by using one of the following methods:

·     Ethernet service instance-to-VSI mapping—This method uses the frame match criterion of an Ethernet service instance to match a list of VLANs on a site-facing Layer 2 interface. The VTEP assigns customer traffic to a VXLAN by mapping the Ethernet service instance to a VSI.

·     VLAN-based VXLAN assignmentThis method maps a VLAN to a VXLAN. When a VLAN is mapped to a VXLAN and VLAN-based VXLAN assignment is enabled, the device automatically performs the following operations:

d.     Creates an Ethernet service instance that uses the VLAN ID as its instance ID on each interface in the VLAN. The matching outer VLAN ID of the Ethernet service instances is the VLAN ID.

e.     Maps the Ethernet service instances to the VSI of the VXLAN.

Do not configure both Ethernet service instance-to-VSI mapping and VLAN-based VXLAN assignment.

Examples

# Enable VLAN-based VXLAN assignment.

Layer 2 Ethernet interface view

Predefined user roles

network-admin

Usage guidelines

An interface enabled with VXLAN over VXLAN does not de-encapsulate incoming VXLAN packets. Do not enable this feature on a transport-facing interface.

By default, the device de-encapsulates an incoming VXLAN packet if the packet's destination UDP port number is the VXLAN destination UDP port number (configured by using vxlan udp-port). For VXLAN packets received from a non-transport-facing interface on the device to traverse the VXLAN network through VXLAN tunnels, perform the following tasks on the interface:

·     Enable VXLAN over VXLAN.

·     Configure Ethernet service instance and VSI settings for matching the VXLAN packets.

When receiving VXLAN packets on the interface, the device adds a second layer of VXLAN encapsulation to the packets and forwards them over VXLAN tunnels.

Examples

# Enable VXLAN over VXLAN on Ten-GigabitEthernet 1/0/1.

Parameters

vsi-name: Specifies the VSI name, a case-sensitive string of 1 to 31 characters.

access-mode: Specifies an access mode. The default access mode is VLAN.

ethernet: Specifies the Ethernet access mode.

vlan: Specifies the VLAN access mode.

track track-entry-number&<1-3>: Specifies a space-separated list of up to three track entry numbers in the range of 1 to 1024. The AC is up only if a minimum of one associated track entry is in positive state.

Usage guidelines

To monitor the status of an AC, associate it with track entries.

To configure this command for an Ethernet service instance, you must first use the encapsulation command to add a frame match criterion to the service instance.

For traffic that matches the Ethernet service instance, the system uses the VSI's MAC address table to make a forwarding decision.

The access mode determines how a VTEP processes the 802.1Q VLAN tags in the inner Ethernet frames assigned to the VSI.

·     VLAN access mode—Ethernet frames received from or sent to the local site must contain 802.1Q VLAN tags.

¡     For an Ethernet frame received from the local site, the VTEP removes all its 802.1Q VLAN tags before forwarding the frame.

¡     For an Ethernet frame destined for the local site, the VTEP adds 802.1Q VLAN tags to the frame before forwarding the frame.

In VLAN access mode, VXLAN packets sent between VXLAN sites do not contain 802.1Q VLAN tags. VXLAN can provide Layer 2 connectivity for different 802.1Q VLANs between sites. You can use different 802.1Q VLANs to provide the same service in different sites.

·     Ethernet access mode—The VTEP does not process the 802.1Q VLAN tags of Ethernet frames received from or sent to the local site.

¡     For an Ethernet frame received from the local site, the VTEP forwards the frame with the 802.1Q VLAN tags intact.

¡     For an Ethernet frame destined for the local site, the VTEP forwards the frame without adding 802.1Q VLAN tags.

In Ethernet access mode, VXLAN packets sent between VXLAN sites contain 802.1Q VLAN tags. VXLAN cannot provide Layer 2 connectivity for different 802.1Q VLANs between sites. You must use the same 802.1Q VLAN to provide the same service between sites.

In VLAN access mode, a Layer 2 interface uses the following rules to process the 802.1Q VLAN tags of traffic for an Ethernet service instance that uses the encapsulation default match criterion:

·     If no other Ethernet service instances exist on the interface, the VLAN tags of incoming traffic are removed before forwarding.

·     If there are other Ethernet service instances on the interface, the VLAN tags of incoming traffic are not removed.

Examples

# On Ten-GigabitEthernet 1/0/1, configure Ethernet service instance 200 to match frames with an outer 802.1Q VLAN tag of 200, and map the instance to VSI vpn1.

Usage guidelines

When local proxy ARP is enabled on distributed VXLAN IP gateways, each gateway learns ARP information independently. A gateway does not forward ARP packets destined for its local VSI interfaces to other gateways. For distributed VXLAN IP gateways to have the same ARP entries, you must enable dynamic ARP entry synchronization.

A controller or the EVPN feature can also synchronize ARP entries among distributed VXLAN IP gateways. When you use a controller or the EVPN feature, do not enable dynamic ARP entry synchronization.

Usage guidelines

If a VXLAN uses distributed gateway services, you must assign the same IP address to the VXLAN's VSI interfaces on different VTEPs. To avoid IP address conflicts, you must specify the VSI interface on each VTEP as a distributed gateway.

Examples

# Specify VSI-interface 100 as a distributed gateway.

Predefined user roles

network-admin

Parameters

ipv4-address: Specifies an IPv4 subnet address in dotted-decimal notation.

wildcard-mask: Specifies a wildcard mask in dotted decimal notation. In contrast to a network mask, the 0 bits in a wildcard mask represent "do care" bits, and the 1 bits represent "don't care" bits. If the "do care" bits in a packet's IP address are identical to the "do care" bits in the specified subnet address, the packet is assigned to the VSI. All "don't care" bits are ignored. The 0s and 1s in a wildcard mask can be noncontiguous. For example, 0.255.0.255 is a valid wildcard mask.

ipv6-address prefix-length: Specifies an IPv6 subnet address and the address prefix length in the range of 1 to 128.

Usage guidelines

You must configure this command on VSIs that share a gateway interface. This command enables the VSI interface to identify the VSI of a packet.

You can assign a maximum of eight IPv4 and IPv6 subnets to a VSI.

You must specify a gateway interface for a VSI before you can assign subnets to the VSI. If you remove the gateway interface from the VSI, the VSI's subnet settings are automatically deleted.

For VSIs that share a gateway interface, the subnets must be unique.

Examples

# Assign subnet 100.0.10.0/24 to VSI vxlan.

<Sysname> system-view

[Sysname] vsi vxlan

undo ipv6 nd distributed-gateway dynamic-entry synchronize

Default

Dynamic ND entry synchronization is disabled for distributed VXLAN IP gateways.

Views

System view

Predefined user roles

network-admin

Usage guidelines

When local ND proxy is enabled on distributed VXLAN IP gateways, each gateway learns ND information independently. A gateway does not forward ND packets destined for its local VSI interfaces to other gateways. For distributed VXLAN IP gateways to have the same ND entries, you must enable dynamic ND entry synchronization.

A controller or the EVPN feature can also synchronize ND entries among distributed VXLAN IP gateways. When you use a controller or the EVPN feature, do not enable dynamic ND entry synchronization.

Examples

# Enable dynamic ND entry synchronization for distributed VXLAN IP gateways.

undo reserve-vlan-interface vlan-interface-id1 [ to vlan-interface-id2 ] global

Default

No VLAN interface resources are reserved.

Views

System view

Predefined user roles

network-admin

Parameters

vlan-interface-id1: Specifies a VLAN ID in the range of 1 to 4094.

vlan-interface-id1 to vlan-interface-id2: Specifies a VLAN ID range. The value range for the vlan-interface-id1 and vlan-interface-id2 arguments is 1 to 4094. The value for the vlan-interface-id2 argument must be greater than or equal to the value for the vlan-interface-id1 argument.

Usage guidelines

The VLAN interface resource reservation of a VLAN conflicts with the VLAN interface creation of this VLAN. Select the VLAN interfaces of unused VLANs for resource reservation. As a best practice, do not create or use a VLAN if its VLAN interface resource is reserved.

As a best practice to simplify management and configuration, reserve VLAN interface resources as follows:

·     Bulk reserve resources of VLAN interfaces that are numbered in consecutive order.

·     Preferentially reserve the VLAN interface resources of VLAN 3000 to VLAN 3500.

You cannot remove the reservation of a VLAN interface resource if this resource is in use.

To establish the connection, you must execute the ovsdb server enable command. You must disable and then re-enable the OVSDB server if it has been enabled.

Examples

# Set up an active OVSDB TCP connection to port 6632 at 192.168.12.2.

<Sysname> system-view

[Sysname] ovsdb server tcp ip 192.168.12.2 port 6632

vtep access port

Use vtep access port to specify a site-facing interface as a VTEP access port.

Use undo vtep access port to restore the default.

Syntax

vtep access port

undo vtep access port

Default

An interface is not a VTEP access port.

Usage guidelines

For controllers to manage a site-facing interface, you must specify the interface as a VTEP access port.

Examples

# Specify Ten-GigabitEthernet 1/0/1 as a VTEP access port.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1

[Sysname-Ten-GigabitEthernet1/0/1] vtep access port

vtep acl disable

Use vtep acl disable to disable the ACLs issued by the OVSDB controller.

Use undo vtep acl disable to enable the ACLs issued by the OVSDB controller.

Syntax

vtep acl disable

undo vtep acl disable

Default

The ACLs issued by the OVSDB controller are enabled on the device.

Usage guidelines

Before you use this command, you must use the vtep enable command to enable the OVSDB VTEP service.

Use the vtep acl disable command on a VTEP to disable all the ACLs issued by the OVSDB controller in order to save ACL resources on the VTEP.

Examples

# Disable the ACLs issued by the OVSDB controller.

<Sysname> system-view

[Sysname] vtep enable

[sysname] vtep acl disable

Related commands

vtep enable

vtep enable

Use vtep enable to enable the OVSDB VTEP service.

Use undo vtep enable to disable the OVSDB VTEP service.

Syntax

vtep enable

undo vtep enable

Default

The OVSDB VTEP service is disabled.

vxlan tunnel flooding-proxy

Use vxlan tunnel flooding-proxy to enable flood proxy on multicast VXLAN tunnels.

Use undo vxlan tunnel flooding-proxy to disable flood proxy on multicast VXLAN tunnels.

Syntax

vxlan tunnel flooding-proxy

undo vxlan tunnel flooding-proxy

Default

Flood proxy is disabled on multicast VXLAN tunnels.

Views

System view

Predefined user roles

Usage guidelines

Flood proxy is supported on multicast VXLAN tunnels only when the OVSDB controller is a NSX controller from VMware.

If you use a flood proxy server, you must enable flood proxy globally on multicast tunnels. Then the multicast tunnels are converted into flood proxy tunnels. The VTEP sends broadcast, multicast, and unknown unicast traffic for a VXLAN to the flood proxy server through the tunnels. The flood proxy server then replicates and forwards flood traffic to remote VTEPs.

After you enable flood proxy on multicast VXLAN tunnels, if the controller issues VSI configuration, the system automatically disables ARP flood suppression on all VSIs issued by the controller. If the controller does not issue VSI configuration, the system does not automatically change the state of ARP flood suppression.

If you do not enable flood proxy on multicast VXLAN tunnels, the system does not automatically change the state of ARP flood suppression regardless of whether the controller issues VSI configuration.

The vxlan tunnel flooding-proxy command and its undo form affect only VXLAN tunnels that are issued after the vxlan tunnel flooding-proxy command.

Examples

# Enable flood proxy on all multicast VXLAN tunnels.

<Sysname> system

[Sysname] vxlan tunnel flooding-proxy
