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 ?
Thank you.

The ethernet (MAC) addresses of other machines in the same layer two ethernet segment. but traffic for these hosts is
broadcast to the local network, and as such I don?t think there would be any practical way to ascertain what layer two equipment was in between a pair of hosts other than by physically looking at it, or manually/automatically logging into equipment (say, via SNMP) in order to view MAC/CAM tables and port assignments.
If you want to know more Please refer for complete syntax and usage information for the commands used in this chapter, refer to the Catalyst 6500 Series Switch Cisco IOS Command Reference, Release 12.2SX at this URL:

The source MAC you ping from should be the MAC address of the VLAN interface on which the end device resides. Issue the command "show interface VLAN X" Where X is the VLAN id of the end device and use the hardware address listed as the source.
