Hi there

We have recently installed CiscoWorks and have started managing all of our
current Cisco kit. The last goal I have is to monitor the "Internet Router"
on the public interface of my ISA firewall, so I was thinking that I could
merely create a new protocol definition and continue as per normal... 

WRONG!!!

I have just been informed that Cisco's CDP protocol is a layer 2 protocol,
and thus cannot be "allowed" through a firewall. Frankly, this just sounds
like a challenge waiting to be accepted... Any takers out there?

Cheers
William R.
