KEEPALIVE TIMER Characteristic
Introduction
The KEEPALIVE TIMER characteristic maintains a virtual circuit between the
access server and service node when no messages are exchanged over a period of
time. If the keepalive timer expires, the access server sends a message to
determine if the service node is still reachable. If the service node fails to respond,
the access server can time out the virtual circuit.
Keepalive Timer Default Values
The keepalive timer value is a trade-off between fast circuit-down detection and
unnecessary network traffic. The factory-set default value of 20 seconds
represents a good compromise. For a heavily loaded Ethernet, use a value from 60
to 180. For applications that require quick notification of a service node failure,
use 10 seconds.
Keepalive Timer Example
The following example shows how to change the keepalive timer to 10 seconds:
