Re: 0x9000

could it be McAfee's NetShield anti-virus for Novell

Re: 0x9000

i don't think so, because the source MAC address = destination MAC Address = MAC address of a cisco router 1720. could it be cdp ?

Re: 0x9000

It's not CDP. CDP is multicast to MAC address 0100.0ccc.cccc, source MAC address is the router who sent the CDP frame.

Ethertype 0x9000 means Enet config test. See the link below:
