packet capture on 6509 switch port

I am getting SNMP authrntication failures on a 6505.

I want to capture those packets to see the source.

Can you create a packet capture like you can on a firewall and apply it to a switch port interface?

Re: packet capture on 6509 switch port

Wilson,

The way to setup the packet capture on 6500 switches is a little different than the way it is used on firewall interfaces. On firewall the packet capture are stored locally on a file but with the switches you have use a third party packet capture toll like ethereal. You have to setup the "port mirroring" on switches to do the packet capture. Please see the links below for the same.

HTH,Please rate if it does.
