- Cisco Employee,
Has anyone experienced duplicate MAC addresss issues with the UCS-B/6120 connected to a 6500? I'm seeing the following on my 6500:
6506#sh arp | inc 0025
Internet 10.1.79.60 0 0025.b501.0005 ARPA Vlan210
Internet 10.1.79.62 4 0025.b501.0007 ARPA Vlan210
Internet 10.1.79.98 51 0025.b501.0005 ARPA Vlan210
I checked my profiles and they appear to each have a uniquely assigned MAC address. The correct entry is 10.1.79.60 and the 6120 should be replying with 0025.b501.006 for 10.1.79.98.
Anyone got any thoughts on how to correct this issue?
