Configuring ANCP Neighbors

From the L2C Configuration mode (config-l2c), you can access the L2C Neighbor Configuration mode, from which you can create and manage ANCP neighbors. Tasks to configure ANCP neighbors are:

• Accessing L2C Neighbor Configuration Mode for ANCP
• Defining an ANCP Neighbor
• Limiting Discovery Table Entries
• Clearing ANCP Neighbors

Accessing L2C Neighbor Configuration Mode for ANCP

You can create an ANCP neighbor and access the L2C Neighbor Configuration (config-l2c-neighbor) mode.

To create the ANCP neighbor and access the L2C Neighbor Configuration mode:

• Issue the neighbor command in L2C Configuration mode.
  host1(config-l2c)#neighbor ACCESS-NODE-1 host1(config-l2c-neighbor)#

You can use the no version to remove a specific ANCP neighbor configuration or, by omitting the neighbor name, all ANCP neighbor configurations.

Defining an ANCP Neighbor

You can define the ANCP neighbor by specifying a neighbor ID in the L2C Neighbor Configuration (config-l2c-neighbor) mode and define the maximum number of branches for the neighbor.

To specify an ANCP neighbor ID and the maximum number of branches that the neighbor can have:

1. From L2C Configuration mode, create an ANCP neighbor and specify the ANCP neighbor ID.
   host1(config-l2c)#neighbor host1(config-l2c-neighbor)#id 1234.5678.9123
2. From L2C Neighbor Configuration mode, specify the maximum number of branches.
   host1(config-l2c-neighbor)#max-branches 50

Limiting Discovery Table Entries

You can specify the maximum number of discovery table entries that a neighbor can have.

To specify the maximum number of entries:

• Issue the max-discovery-table-entries command in L2C Neighbor Configuration mode.
  host1(l2c-neighbor)#max-discovery-table-entries 4000

You can use the no version to return the maximum number of discovery table entries to its default value, 10,000 entries.

Note: Using this command to change the maximum number of entries when an already greater number of current entries exists in the discovery table does not remove any existing entries. Instead, future entries are prevented. For example, if the current table contains 5000 entries, and you specify a maximum of 4000 entries, the software does not remove any existing entries from the table. The software prevents any new entries until the number of table entries falls below the specified maximum.

Clearing ANCP Neighbors

You can clear an existing ANCP neighbor and reset the specified GSMP neighbor session. Issuing the clear l2c neighbor command removes all QoS parameter instances associated with the neighbor, including those associated with the QoS downstream rate and QoS cell mode applications.

To clear an existing ANCP neighbor:

• Issue the clear l2c neighbor command in Privileged Exec mode.
  host1#clear l2c neighbor ACCESS_NODE_1

There is no no version.
