Has anyone ever heard of network traffic that's sourced from a multicast
ethernet address? I've seen error messages on a Catalyst 4000 that reads:
%SYS-4-P2_WARN- 1/Invalid traffic from multicast source address
45-00-05-dc-73-a6 on port 1/1
I know that address isn't a multicast address but it's not registered to any
Ethernet vendor codes either. Cisco says this is probably from a traffic
generator (like SmartBits) but I don't think that's being run anywhere. Has
anybody seen this MAC address or something like it?
Thanks,
