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.

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

host1#show l2c neighbor brief 
        Name           Mac Address     Remote Address   Protocol State 
-------------------- ---------------- ---------------- ----------------
accessnode1          0abc.0abc.0abc   null             EMPTY

To display the number of active neighbors on the router:

host1(config)#show l2c neighbor summary
L2C:
  Number of configured Neighbors: 1
  Number of Neighbors in GSMP_ESTAB state: 1
  Number of neighbors in GSMP_EMPTY state: 0
