The usage of 'caputre' command in ACE

Unanswered Question
Jan 14th, 2008

I have a question about the capture command.

I would like to capture the traffic through ACE. So I tried the capture traffic like below

#capture aaa all, but error.

the error message is 'the buffer not set'

the error message is not extractly but the same meaning.

How can I use the capture command?

Am I missed the configuration?

I have this problem too.

Capture is used to sniff traffic flowing through the ace itself.

What you were probably looking for is the command "debug".

try -> debug aaa all

This will show you all AAA related traffic/events.

Be sure to remove the debug condition before logging out with "undebug all"

If you want to capture traffic you need an access-list.


conf t

access-list All permit ip any any


capture all access-list All bufsize 2048 circular-buffer

That should help you capture/sniff traffic passing through the ACE itself.

Capture and Debug are two different things. :)

Hope it helps
