Suppress Address Resolution Protocol and Neighbor Discovery on VLAN or Bridge Domain

Provide an option to enable or disable suppress-arp or nd (supress address resolution protocol or neighbor discovery) at the tenant network level so that you can choose to enable suppress-arp or nd per tenant network.

This option is mainly useful for a single rack small data center deployment where the suppress-arp or nd configuration on tenant network is not needed.

EFA configures the suppress-arp or nd on the VLAN or BD (Bridge Domain) associated with the L3 tenant networks belonging to the distributed router.
EFA does not configure the suppress-arp or nd on the VLAN or BD associated with the L3 tenant networks belonging to the centralized router.
EFA doesn‘t configure the suppress-arp or nd on the VLAN or BD associated with the L2 tenant networks.

Note

For all the L3 tenant networks belonging to the distributed router, suppress-arp or nd is displayed as “true” after the upgrade from 2.4.x to 2.5.0.
For all the L3 tenant networks belonging to the centralized router, suppress-arp or nd is displayed as “false” after the upgrade from 2.4.x to 2.5.0.
For all the L2 tenant networks, suppress-arp or nd is displayed as “false” after the upgrade from 2.4.x to 2.5.0.

To configure suppress ARP or ND for performance tuning when you create a VLAN or BD, run the following command:

efa tenant epg create --name <epg-name> --tenant <tenant-name> 
                 --port <port-list> --switchport-mode <trunk|access> --ctag-range <ctag-range> 
                 --anycast-ip <ctag:anycast-ipv4> --anycast-ipv6 <ctag:anycast-ipv6> --vrf ten1vrf1
                 --suppress-arp <ctag:true|false> --suppress-nd <ctag:true|false>
 efa tenant epg update --name <epg-name> --tenant <tenant-name> --operation vrf-add 
                  --anycast-ip <ctag:anycast-ipv4> --anycast-ipv6 <ctag:anycast-ipv6>  --vrf ten1vrf1
                  --suppress-arp <ctag:true|false> --suppress-nd <ctag:true|false>
efa tenant epg update --name <epg-name> --tenant <tenant-name> --operation ctag-range-add 
                 --ctag-range <ctag-range> --anycast-ip <ctag:anycast-ipv4> --anycast-ipv6 <ctag:anycast-ipv6>
                 --suppress-arp <ctag:true|false> --suppress-nd <ctag:true|false>
 efa tenant epg update --name <epg-name> --tenant <tenant-name> --operation anycast-ip-add 
	  --anycast-ip <ctag:anycast-ipv4> --anycast-ipv6 <ctag:anycast-ipv6>
                  --suppress-arp <ctag:true|false> --suppress-nd <ctag:true|false>
