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 the VSI vsi1.

<Sysname> system-view
[Sysname] vsi vsi1
[Sysname-vsi-vsi1] arp suppression enable
