We have are experiencing an issue with our Core switch not propagating the CDP neigh to connected nodes. The Core is seeing direct trunk nodes and displays them in the sh cdp neigh. From the node side however we cannot see the Core switch CDP info.
In addition to this (and related) we are having VTP propagation issues as well. Core sw is our single VTP server. I have verified that all nodes are in client, running v2, and in correct vtp domain. The revision number is 10 behind the current on all nodes in the LAN. Have rebooted all nodes, and have tried on several to del vlan.dat and bring back up. This resulted in a pickup of the older VTP rev. Tac was sure we had another server as well, but they have verified the issue.
Tac is pointing the to the CDP issue being the root cause. Has anyone seen this before?
Our Core is a 6509E with lastest IOS.
