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.

Default

An Ethernet service instance does not contain a frame match criterion.

Views

Ethernet service instance view

Predefined user roles

network-admin

mdc-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.

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: Matches frames that do not match any other Ethernet service instance on the interface. On an interface, you can configure this criterion only in one Ethernet service instance. The Ethernet service instance 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 frame match criteria of Ethernet service instances cannot overlap on an interface.

When you configure frame match criteria on different Ethernet service instances on an interface, follow these restrictions and guidelines:

· The matching VLAN ID ranges of two Ethernet service instances cannot overlap.

· The criterion specified by the tagged keyword is mutually exclusive with the criterion specified by the s-vid or c-vid keyword.

· An Ethernet service instance cannot work correctly if the following conditions exist:

? The Ethernet service instance has a frame match criterion specified by the c-vid keyword.

? All of the following commands are used on the Ethernet service instances on the interface:

- encapsulation s-vid vlan-id-list [ only-tagged ]

- encapsulation s-vid vlan-id-list c-vid { vlan-id-list | all }

- encapsulation c-vid vlan-id-list

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.

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.

<Sysname> system-view

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

mdc-admin

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.

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.

Examples

# Disable flooding of local broadcast traffic to remote sites for VSI vsi1.

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

You must configure an interface as an IGMP host if its IP address is the source IP address of multicast VXLAN packets. The IGMP host feature enables the interface to send IGMP reports in response to IGMP queries before it can receive traffic from a multicast group.

For this command to take effect, you must use the multicast routing command to enable IP multicast routing.

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.

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.

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 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 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 remote MAC address entry, make sure the VSI's VXLAN has been specified on the VXLAN or VXLAN-DCI tunnel.

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.

Predefined user roles

network-admin

mdc-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 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

nest: Adds VLAN tags.

c-vid: Specifies an inner VLAN tag.

s-vid: Specifies an outer VLAN tag.

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

remark: Maps VLAN tags.

1-to-1: Performs one-to-one mapping to replace one VLAN tag of packets with the specified VLAN tag.

2-to-1: Performs two-to-one mapping to replace the outer and inner VLAN tags of double tagged packets with the specified VLAN tag.

1-to-2: Performs one-to-two mapping to replace the VLAN tag of single tagged packets with the specified outer and inner VLAN tags.

2-to-2: Performs two-to-two mapping to replace the outer and inner VLAN tags of double tagged packets with the specified outer and inner VLAN tags.

strip: Removes VLAN tags.

symmetric: Applies the reverse VLAN tag processing rule to outgoing traffic.

Usage guidelines

For this command to take effect, follow these restrictions and guidelines:

· Do not use this command on a VXLAN IP gateway. This command and VXLAN IP gateway configuration are mutually exclusive.

· You must configure a match criterion by using the encapsulation command (except encapsulation default), and specify Ethernet access mode by using the xconnect vsi command.

If the rewrite inbound tag command and a QoS policy are both used, this command takes effect prior to the QoS policy. The QoS policy takes effect on the traffic that has been processed by using the rewrite inbound tag command.

You cannot both specify the symmetric keyword in the rewrite inbound tag command and configure the rewrite outbound tag command.

When you configure a nest rule for incoming traffic, follow these restrictions and guidelines:

· VXLAN supports a maximum of two VLAN tags.

? To add an outer VLAN tag for untagged or single-tagged frames, configure a nest s-vid vlan-id rule. To add one VLAN tag for untagged frames, you must use a nest s-vid vlan-id rule instead of a nest c-vid vlan-id rule.

? To insert an inner VLAN tag in a single-tagged frame, configure a nest c-vid vlan-id rule. If the encapsulation tagged frame match criterion is used, the 802.1p priority in the added inner VLAN tag is set to 0. If the symmetric keyword is specified, the device does not strip the inner tag of the returned outgoing traffic.

? To add two VLAN tags to untagged frames, configure a nest s-vid vlan-id c-vid vlan-id rule. You cannot add two tags to tagged frames.

· If the nest rule specifies an outer VLAN (s-vid vlan-id) and the symmetric keyword, you must add the site-facing interface to the specified outer VLAN.

When you configure a re-mark rule for incoming traffic, follow these restrictions and guidelines:

· The VLAN tag of a single-tagged frame is processed as the outer VLAN tag. To perform one-to-one mapping for a single-tagged frame, configure a remark 1-to-1 s-vid vlan-id rule.

· If you use a remark 2-to-1 c-vid vlan-id rule with the encapsulation tagged criterion, the 802.1p priority in the new inner VLAN tag is copied from the original outer VLAN tag.

· If you use a remark 1-to-2 s-vid vlan-id c-vid vlan-id rule with the encapsulation tagged criterion, the 802.1p priority in the new inner VLAN tag is set to 0.

· If you use the symmetric keyword in the re-mark rule, follow these restrictions and guidelines:

? If you specify an outer VLAN tag in the rule, you must configure the frame match criterion to match outer VLAN tags.

? If both outer and inner VLAN tags are specified in the rule, you must configure the frame match criterion to match both outer and inner VLAN tags.

? If a remark 1-to-1 c-vid vlan-id rule is configured, the device does not perform reverse one-to-one VLAN mapping for the returned outgoing traffic.

When you configure a strip rule for incoming traffic, follow these restrictions and guidelines:

· The VLAN tag of a single-tagged frame is processed as the outer VLAN tag. To remove its VLAN tag, configure the strip s-vid rule.

· If the strip rule contains the symmetric keyword, the following restrictions apply:

? If the rule strips the outer VLAN tag, you must configure the frame match criterion to match outer VLAN tags.

? If the rule strips both inner and outer VLAN tags, you must configure the frame match criterion to match both outer and inner VLAN tags.

? The device does not add the VLAN tag that was removed in the inbound direction for the returned outgoing traffic.

· If the encapsulation tagged frame match criterion is used, do not configure the strip s-vid rule. This rule cannot take effect on the matching frames.

To modify the VLAN tag processing rule for incoming traffic, you must first delete the existing rule by using the undo rewrite inbound tag command.

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.

relay-agent: Enables relay agent for the tunnel to transmit IPoE packets to the remote VTEP. If you do not specify this keyword, relay agent is disabled on the tunnel.

ipoe: Enables IPoE relay agent.

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.

If you enable IPoE relay agent on a VXLAN tunnel, the device uses this tunnel to send IPoE packets received from the associated VXLAN to the remote VTEP. Typically, relay agent is used on DPs in the forwarding-control separation solution. For a DP to send control traffic (IPoE packets) to a CP, you must enable IPoE relay agent on the VXLAN tunnel between the DP and the CP.

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.

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. 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.

Examples

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

Predefined user roles

network-admin

mdc-admin

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 assignment—This 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:

a. 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.

b. 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.

<Sysname> system-view

[Sysname] vxlan vlan-based

vxlan vni

Parameters

vxlan-id: Specifies a VXLAN ID in the range of 0 to 16777215.

Usage guidelines

Before you map VLANs to VXLANs, enable VLAN-based VXLAN assignment by using the vxlan vlan-based command.

You cannot map VLAN 1 to any VXLAN.

Do not map a VLAN to the L3 VXLAN ID of EVPN.

If you map a VLAN to a nonexistent VXLAN, the configuration takes effect after the VXLAN is created.

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—The VTEP processes 802.1Q VLAN tags of Ethernet frames as follows:

? If the Ethernet service instance uses the encapsulation untagged criterion, Ethernet frames received from or sent to the local site does not contain 802.1Q VLAN tags.

- The VTEP directly forwards untagged Ethernet frames received from the local site.

- The VTEP does not add 802.1Q VLAN tags to Ethernet frames when forwarding them to the local site.

? If the Ethernet service instance uses any other criterion except encapsulation default, 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.

? The Ethernet service instance cannot use the encapsulation default criterion if VLAN access mode is used.

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.

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.

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.

Usage guidelines

By default, the device learns ARP information of remote VMs from packets received on VXLAN tunnel interfaces. To save resources on VTEPs in an SDN transport network, you can temporarily disable remote ARP learning when the controller and VTEPs are synchronizing entries. After the entry synchronization is completed, use the undo vxlan tunnel arp-learning disable command to enable remote ARP learning.

As a best practice, disable remote ARP learning for VXLANs only when the controller and VTEPs are synchronizing entries.

Examples

# Disable remote ARP learning for VXLANs.
