NX-OS Duplicate ARP Detection Suppression in DCI HSRP

[Conchobhar Bradigan]

Hi

In NX-OS release 4.2(8) a feature was introduced to supress duplicate IP address warning messages in DCI environments.

When using the same HSRP addresses in both DCs but blocking the HSRP exchange, ARP still detects these duplicate configuration and writes log messages. There obviously is a feature to suppress this but I do not find any reference how to enable it.

Can anyone help? Thanks.

Are you asking for the command?

It's "no ip arp gratuitous hsrp duplicate"
