Newbie question - collision checking on Catalyst 4006

[Edmee]

I want to check if collisions are occuring on a certain port number on a Catalyst 4006 switch. Would someone be so kind as to point me in the right direction? I have basic knowledge of the Cisco commands so I know how to connect and "move about" but after not using this knowledge for about 2 years I have found myself to be rather rusty. : ) Thanks in advance!

Errrrm, not sure if your particular switch is different but normally you go into priviledged mode (enable), type show interface (or show interface fastethernet 0/1 etc) and the information should be displayed for you there.

I hope you don't have any collisions, cause the 4006 creates a collision domain per switch port, which would normally eliminate collisions (especially if you're in full duplex). If you are getting collisions, try swapping the NICs. But getting back to your question, you could do a show interface command, or do a term mon and debug int to see what's going on real-time (can create a lot of messages, you might want to dump them to a syslog server.)

Ah yes, of course! Thanks guys for refreshing my very rusty memory. : ) Edmée de Klerk
