Usage guidelines

For this command to take effect, you must map the Layer 3 interface to a VSI. If you modify the VSI mapping, packet statistics of the interface are cleared.

Examples

# Map HundredGigE 1/0/1 to VSI vsia and enable packet statistics on the interface.

<Sysname> system-view

[Sysname] interface hundredgige 1/0/1

[Sysname-HundredGigE1/0/1] xconnect vsi vsia

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

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 in the range of 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

This 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.

Examples

# Simulate local VM 1ea3-c0be-0206 to test the reachability of remote VM 1ea3-b77b-0106 in VXLAN 100.

Predefined user roles

network-admin

Parameters

s-vid vlan-id-list: Matches frames that are tagged with the specified outer 802.1Q VLAN IDs. The vlan-id-list argument 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.

s-vid vlan-id-list c-vid vlan-id-list: Matches frames that are tagged with the specified outer and inner 802.1Q VLAN IDs. The vlan-id-list argument 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.

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.

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

Usage guidelines

An Ethernet service instance can contain only one match criterion. To change the match criterion, first execute the undo encapsulation command to remove the original criterion. When you remove the 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 HundredGigE 1/0/1. The service instance matches frames that have an outer 802.1Q VLAN ID of 111 and an inner 802.1Q VLAN ID of 20 or in the range of 30 to 40.

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.

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.

To confine a kind of flood traffic to the site-facing interfaces, use this command to disable flooding for that kind of flood traffic on the VSI bound to the VXLAN. The VSI will not flood the corresponding frames to VXLAN tunnel interfaces.

Examples

# Disable flooding for VSI vsi1.

<Sysname> system-view

[Sysname] vsi vsi1

[Sysname-vsi-vsi1] flooding disable

group

Use group to assign a VXLAN a multicast group address for flood traffic, and specify a source IP address for multicast VXLAN packets.

Use undo group to restore the default.

Syntax

group group-address source source-address

undo 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

network-admin

Parameters

ctag: Specifies the Ctag mode.

mac: Specifies the MAC address mode.

normal: Specifies the normal mode.

stag: Specifies the Stag mode.

Usage guidelines

Creation of VXLAN tunnels and MAC address entries requires hardware resources, which are limited on the device. You can select a VXLAN hardware resource mode to distribute hardware resources between VXLAN tunnels and MAC address entries depending on your network requirements..

·     MAC address mode—Assigns more hardware resources to MAC address entries. Use this mode only on IPv4-based VXLANs.

·     Normal mode—Assigns more hardware resources to VXLAN tunnels. In this mode, a VXLAN tunnel interface can be the outgoing interface of a network route.

·     Ctag mode—Assigns more hardware resources to VXLAN tunnels, and enables the device in Layer 3 forwarding mode to process packets to be forwarded through VXLAN tunnels as follows:

¡     Adds the tag of the CVLAN ID in the ARP entry used for forwarding to packets before VXLAN encapsulation.

¡     Does not add VLAN tags to packets if the ARP entry does not contain a CVLAN ID.

·     Stag mode—Assigns more hardware resources to VXLAN tunnels, and enables the device in Layer 3 forwarding mode to process packets to be forwarded through VXLAN tunnels as follows:

¡     Adds the tag of the SVLAN ID in the ARP entry used for forwarding to packets before VXLAN encapsulation.

¡     Does not add VLAN tags to packets if the ARP entry does not contain an SVLAN ID.

In MAC address mode or normal mode, the device does not add VLAN tags to packets before VXLAN encapsulation.

In Ctag mode or Stag mode, the maximum numbers of VXLAN tunnels and MAC address entries are the same as those in normal mode. In addition, a VXLAN tunnel interface can be the outgoing interface of a network route.

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: Specifies a Layer 3 interface by its type and number.

interface interface-type interface-number service-instance instance-id: Specifies an Ethernet service instance on a Layer 2 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 tunnel interface. The tunnel-number argument represents the tunnel interface number. The tunnel interface must already exist. This option applies to remote MAC addresses.

vsi vsi-name: Specifies the 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 can be generated by a variety of methods, including MAC entries manually added, dynamically learned, and advertised by BGP EVPN.

When you add a local MAC address entry, make sure the specified Layer 3 interface or 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 tunnel.

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

·     EVPN re-establishes VXLAN 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 VXLAN 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.

For more information about EVPN, see EVPN Configuration Guide.

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

Predefined user roles

network-admin

Parameters

tunnel-number: Specifies a tunnel interface number in the range of 0 to 70000. The tunnel must be a 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.

Usage guidelines

This command assigns a VXLAN tunnel to a VXLAN to provide Layer 2 connectivity for the VXLAN between two sites. Alternatively, you can use VXLAN IS-IS for automatic VXLAN tunnel assignment.

You can assign multiple VXLAN tunnels to a VXLAN, and configure a VXLAN tunnel to trunk multiple VXLANs. For a unicast-mode VXLAN, the system floods unknown unicast, multicast, and broadcast traffic to each tunnel in the VXLAN.

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.

Examples

# Assign VXLAN tunnels 0 and 1 to VXLAN 10000.

<Sysname> system-view

[Sysname] vsi vpna

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 can 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.

Examples

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

<Sysname> system-view

[Sysname] interface tunnel 9 mode vxlan

Parameters

ipv4-address: Specifies an IPv4 address.

Usage guidelines

IMPORTANT

IMPORTANT:

For correct VXLAN deployment and VTEP management, do not manually specify tunnel-specific source addresses for VXLAN tunnels if OVSDB is used.

A VXLAN tunnel uses the global source address if you do not specify a source interface or source address for the tunnel.

The global source address takes effect only on VXLAN tunnels. IPv4 VXLAN tunnels use the global IPv4 source address. IPv6 VXLAN tunnels use the global IPv6 source address.

Examples

# Specify 1.1.1.1 as the global source address for VXLAN tunnels.

<Sysname> system-view

[Sysname] tunnel global source-address 1.1.1.1

Predefined user roles

network-admin

Parameters

tagged: Specifies the tagged mode. In this mode, the VTEP adds a VLAN tag to a VXLAN packet.

untagged: Specifies the untagged mode. In this mode, the VTEP does not add a VLAN tag to a VXLAN packet.

Usage guidelines

If the device is a VTEP, enable Layer 2 forwarding for VXLANs. If the device is a VXLAN IP gateway, enable Layer 3 forwarding for VXLANs.

In Layer 3 forwarding mode, the device uses the ARP or ND table to forward IPv4 or IPv6 traffic for VXLANs. In Layer 2 forwarding mode, the device uses the MAC address table to forward traffic for VXLANs.

You must delete all VSIs, VSI interfaces, and VXLAN tunnel interfaces before you can change the forwarding mode.

If you enable Layer 3 forwarding for VXLANs, the tagging status of VXLAN packets is not determined by the link type of the outgoing interface. You must use this command to set the tagging mode of VXLAN packets.

·     Set the tagging mode to untagged if the following requirements are met:

¡     The link type of the outgoing interface is access, trunk, or hybrid.

¡     VXLAN packets are transmitted to the next hop through the PVID of the outgoing interface.

·     Set the tagging mode to tagged if the following requirements are met:

¡     The link type of the outgoing interface is trunk or hybrid.

¡     VXLAN packets are transmitted to the next hop through a VLAN other than the PVID of the outgoing interface.

If you do not set the tagging mode when you execute this command, the untagged mode is used.

You must delete all VXLAN tunnel interfaces before you can change the tagging mode of VXLAN packets.

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 varies by AC type.

·     If the AC is a Layer 3 interface or subinterface, the default access mode is as follows:

¡     For a VLAN interface, the default access mode is VLAN. For a Layer 3 interface of another type, the default access mode is Ethernet.

¡     For a Layer 3 subinterface, the default access mode is VLAN.

·     If the AC is an Ethernet service instance, the default access mode is VLAN.

ethernet: Specifies the Ethernet access mode.

vlan: Specifies the VLAN access mode.

track track-entry-number&<1-15>: Specifies a space-separated list of up to 15 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 traffic match criterion to the service instance.

For traffic that matches the Ethernet service instance or Layer 3 interface, 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.

After you modify the access mode on a Layer 3 subinterface AC, local VMs that access the VXLAN network through the subinterface cannot communicate with remote VMs. To resolve this issue, you must clear the ARP entries on the local VMs or configure them to periodically send gratuitous ARP packets.

# Map HundredGigE 1/0/1 to VSI vpn1.

arp distributed-gateway dynamic-entry synchronize

Use arp distributed-gateway dynamic-entry synchronize to enable dynamic ARP entry synchronization for distributed VXLAN IP gateways.

Use undo arp distributed-gateway dynamic-entry synchronize to disable dynamic ARP entry synchronization for distributed VXLAN IP gateways.

Syntax

arp distributed-gateway dynamic-entry synchronize

undo arp distributed-gateway dynamic-entry synchronize

Default

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

Views

System view

Predefined user roles

network-admin

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 it 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 EVPN, do not enable dynamic ARP entry synchronization.

Examples

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

Views

VSI view

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

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.

port port-number: Specifies the destination port for the TCP connection. The value range for the port-number argument is 1 to 65535.

Usage guidelines

The device can have a maximum of eight active OVSDB TCP connections.

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

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

network-admin

Usage guidelines

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.

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
