Hi, I've been getting the follwoing message on my c2600 (version 13.3) router since last december (according to the log file).
005179: .Dec 28 04:35:08.652 AUS: %IP-4-DUPADDR: Duplicate address xxx.xxx.xxx.xx on
FastEthernet0/0, sourced by 0015.f987.941a
The symptom of the problem is that occassionally the network looses connactivity.
The mac addresses are both for Cisco devices. One is the router and i'm not sure what the other is possibly a firewall.
The Cisco site says that we can change the mac address of one of the offending items ?
Which would be the best one to change?
How can i find out what the other device is?
What if any issue arise with changing the mac address ?
Proably other questions that i should be asking as well, but i'll get to those later.
thanks in advance for any reponses.
