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.

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.

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.

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 to match frames that have an outer 802.1Q VLAN ID of 111.

Predefined user roles

network-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.

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.

You cannot specify the unknown-multicast or unknown-unicast keyword alone. If you specify one of the keywords, you must also specify the other.

Default

VXLAN VSIs do not have static MAC address entries.

Views

System view

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 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.

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

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.

On a DR member device, specify the source IPv4 address as the local VTEP IP address.

load-balance: Configures load balancing parameters. If you do not specify this keyword, the command tests only one of the multiple paths to the VXLAN tunnel destination.

vxlan-source-udpport vxlan-source-udpport end-vxlan-src-udpport: Specifies a source UDP port range for VXLAN echo requests. The value range for UDP port numbers is 49152 to 65535. The default start UDP port number is 4789. If you do not specify an end UDP port number, the end UDP port number is the start UDP port number.

source-address lb-src-address: Specifies the source IPv4 address used for load balancing calculation.

destination-address lb-dest-address: Specifies the destination IPv4 address used for load balancing calculation.

protocol: Specifies the protocol used for load balancing calculation.

udp: Specifies UDP.

lb-protocol-id: Specifies a protocol number in the range of 1 to 255.

source-port lb-src-port: Specifies a source port number used for load balancing calculation, in the range of 1 to 65535.

destination-port lb-dest-port: Specifies a destination port number used for load balancing calculation, in the range of 1 to 65535.

source-mac lb-source-mac: Specifies a source MAC address used for load balancing calculation.

destination-mac lb-destination-mac: Specifies a destination MAC address used for load balancing calculation.

Usage guidelines

Use this command to test the connectivity of a VXLAN tunnel in a VXLAN or EVPN VXLAN network when the tunnel has traffic loss or interruption issues.

Before you execute this command for a VXLAN tunnel, you must enable overlay OAM on the tunnel destination device by using the overlay oam enable command.

The VTEP can distribute VXLAN echo requests among multiple paths to the destination based on the source UDP port. When a VXLAN tunnel has multiple paths on the transport network, you can configure load sharing parameters to ensure accuracy of the test result. You can use one of the following methods to configure source UDP ports for VXLAN echo requests:

· Specify a source UDP port range. The device will send VXLAN echo requests sourced from each UDP port in the UDP port range. You need to execute the ping vxlan command only once.

· Specify load balancing parameters such as source and destination MAC addresses, source and destination IP addresses, and protocol for the VTEP to calculate a source UDP port number. You need to execute the ping vxlan command multiple times to test connectivity of all paths.

The load balancing parameters change only the source UDP port number of VXLAN echo requests. Other fields of the requests will not be changed.

If you specify the vxlan-source-udpport vxlan-source-udpport [ end-vxlan-src-udpport ] parameters, the number of VXLAN echo requests sourced from each UDP port in the UDP port range is determined by the -c count parameter.

Examples

# Test connectivity of VXLAN 1 that is sourced from 11.11.11.11 and destined for 22.22.22.22.

<Sysname> ping vxlan vxlan-id 1 tunnel-source 11.11.11.11 tunnel-destination 22.22.22.22
