Display information about the

Resilient ARP state

Note that the above configuration specifies the VLAN interface through which Resilient packets are sent,

whereas all the VLAN interfaces can receive Resilient ARP packets.

Resilient ARP Configuration Example

Network requirements

There are four units in an IRF network: unit 1 to unit 4. Unit 1 and unit 3 connect to another switch

(Switch) through link aggregation. If the connection between unit 1 and unit 3 and the connection

between unit 2 and unit 4 break off, there will be two Layer 3 switches with the same configuration in the

network. In this case, problems occur in packets forwarding between the fabric and the Switch. You can

enable the Resilient ARP function for the fabric to avoid the problems. For security concerns, you need

to enable MD5 authentication function. The ports through which unit 3 and unit 4 connect to the Switch

belong to VLAN 2.
