I am receiving the error %ARP-3-DUP_VADDR_SRC_IP on two Nexus 7000 switch that is configured with HSRP. I only see this error when the Nexus performs a failover to the HSRP standby unit. I personally think this can be safely ignored,but wanted to get another opinion.
I can generate the error when i initiate the failover of several SVIs that are configured for HSRP. I do not see the error when failover doesn't happen.
I haven't been unable to find any documentation for Nexus on this error.
I have found documentation on this error for Catalyst switches and they seem to indicate a loop in the network. I can confirm that there are no loops in the network.
Has anyone else seen this happen on a Nexus? Any links to documentation would be great too.
