Subject: CDP Neighbor on ATM int's
Group,
I'm renting some time on an ATM rack tonight and have a question about CDP.
I'm having a hard time getting CDP to work. Has anyone else tried to use CDP
on ATM int's ? For a little while, I was thinking it wasn't supported over
ATM, but I was wrong. From CCO :
<snip>
CDP runs on all media that support Subnetwork Access Protocol (SNAP),
including local-area network (LAN), Frame Relay, and Asynchronous Transfer
Mode (ATM) physical media. CDP runs over the data link layer only.
Therefore,
two systems that support different network-layer protocols can learn about
each other.
So, I config'ed a PVC with aal5snap encap and CDP still does not find any
neighbors. When I try to enable it on the ATM int, I get this error :
"% CDP is not supported on this interface, or for this encapsulation " My
interface is a multipoint which might be the reason.
Any ideas ? I've found CDP to be a life saver when I don't know much about
the remote device (when I remember to use it).
Thanks, Gregg
