Reading the docs it states there maybe a miss configuration on the router


Error Message     ARP-4-OWN_SRCMAC Format: Received packet with a local source MAC 
address (%s) from %s on %s 

Explanation    There may be a connected router sending packets with local MAC address.

Recommended Action    Check all routers on the interface for a misconfiguration.

I have the same problem on my management interface Nexus K9

%ARP-4-OWN_SRCMAC:  arp [xxxx]  Received packet with a local source MAC address (xxxxxx) from 10.x.x.x on mgmt0

Hi, did this issue fix, what was the root cause.

Thanks

We have vPC setup between two Cisco Nexus 9504s.

We are also facing this same errors:

The Nexus switches are configured for HSRP and vPC for redundancy. we verified the SVI configuration which looks good.

 

Please help with a solution for this issue.
