RE: ACL Monitoring

I think a better solution maybe to implement TACACS+ and resrict rights
on who can do that..
Sounds like you don't trust someone.....
I'd try that first...


If you anticipate doing a lot of this kind of monitoring in the future you
may want to take a look at the "expect" programming language , which has very simple "send"/"expect" constructs.
E.g. send "show acl 101/r" expect "access-list .." etc. Perl also allows
similar although is probably not quite as easy to pick up if you've never
done this kind of thing before.

Essentially you'd write a quick script to telnet or ssh to the router "send"
your commands, expect a result and do something based on that result. As I
said, its worth the time investment and you'll find once you get the script
done you can just reuse it for many other tasks.

The TACACS+ suggestion is also good.. Not only would it allow you to limit
who (authentication) can do what (authorization).. The accounting features
would also provide a log entry if an authorized user did do a no access-list
101.. You could then write a shell script to parse the accounting log.


Used in CCR, and adapted for

  Cisco IOS
  Cisco Catos
  Pix OS
  Cisco VPN 3000 os

Really nice thing.
