What chassis and line cards do you run? Is the Ethernet0/0 a physical interface or an internal (virtual) interface.
This error can be due to real collisions on physical interfaces due to duplex mismatch. But I also met this error condition on internal (virtual) interface on an uBR10012 chassis (a Cable Modem Termination System based on a 10000 architecture) of one of my customers. In that chassis, the Ethernet0/0 interface is in fact a kind of internal bus used for the PRE to communicate with the line cards. When I noticed this problem on the above mentionned 10012 chassis, we also had other problems (line card reboots). After long (very long) analysis with the TAC without success, we finally proceeded with a RMA. Since then, I saw this collision condition only after the boot/reload of the equipment. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
