That 6500 is our campus backbone. It routes between our vlans. It runs 12.2(18)SXF8. show catalyst6000 will list 000f.35ef.c400 as first mac address. I'm trying to L2 traceroute another mac address.
Error is : Error: Mac found on multiple vlans.
What mac address (of this 6500) should be specified as source to avoid this error message ?
