Monitoring ANCP Neighbors
Purpose
Display information about all known ANCP neighbors or specified ANCP neighbors on the router along with their configurations.
You can use the brief keyword to show limited information. You can use the summary keyword to display the number of active neighbors.
Action
To display information about a specified ANCP neighbor:
host1#show l2c neighbor name accessnode_1002 Neighbor Name: accessnode_1002 Neighbor Id: 0abc.0abc.1002 Maximum Branches: 10 Topology Discovery: true Maximum Discovery Entries: 10000 Ip address: 1.1.1.2 TCP port: 1025 Connection Time: 03/02/2006 11:06:16 Add Branches Sent: 0 Delete Branches Sent: 0 Line-configurations: 0 OAM Loopback Requests Sent: 0 OAM Loopback Responses Received: 0 Protocol State: GSMP_ESTAB
To display limited details about ANCP neighbors on the router:
host1#show l2c neighbor brief
