How do I create an ACL to filter non-important output?

Hi all,

I have the following output out of a 7200 and I want to filter out the non-important stuff and only view via the telnet prompt the important stuff:

Not Important to see:

1w4d: ICMP: echo reply sent, src 3.144.228.5, dst 3.147.180.5

IMPORTANT:

1w4d: ICMP: dst (3.146.4.201) frag. needed and DF set unreachable sent to 3.144.232.238

My Output:

Re: How do I create an ACL to filter non-important output?

I don't think it is possible to filter debug messages on the console. If you find one, could you share it through this forum.

I would advise to sent your debug output to a Syslog server (assure it's located near the router involved because of possible traffic storms). Using Unix filtering commands (cat / grep) you can select the messages you want to have displayed.
