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?
