Configuring ANCP

ANCP uses several global-level configuration commands to enable ANCP to function on the router.

Creating a Listening TCP Socket for ANCP

Use the l2c ip listen command to create a listening TCP socket for ANCP. ANCP monitors port 6068 for ANCP TCP connection requests.

l2c ip listen

• Use to create a listening TCP socket in the current virtual router context.
• Example

  host1(config)#l2c ip listen

• Use the no version to remove the listening TCP socket and stop any new sessions from being established. The no version does not terminate any existing GSMP sessions.
• See l2c ip listen.

Accessing L2C Configuration Mode for ANCP

Use the l2c command to launch the L2C Configuration (config-l2c) mode for ANCP. In this mode, you can define session timeout values and access the L2C Neighbor Configuration mode to configure an ANCP neighbor.

l2c

• Use to launch the L2C Configuration (config-l2c) mode for ANCP.
• Example

  host1(config)#l2c

  host1(config-l2c)#

• Use the no version to remove all ANCP configurations.
• See l2c.

Defining the ANCP Session Timeout

In L2C Configuration (config-l2c) mode, you can use the session-timeout command to specify the ANCP session timeout value. The timer range is 1–25 seconds with a default value of 25 seconds.

session-timeout

• Use to define the ANCP session timeout value (in seconds).
• Example

  host1(config-l2c)#session-timeout 10

• Use the no version to revert the session timeout to its default setting, 25 seconds.
• See session-timeout.
