Configuring a Session Keepalive on the Router
This task describes how to configure the keepalive feature on the router, using either ARP or ICMP.
Because the session keepalive feature is checking for the subscriber’s health and presence, this feature
is applied only to the session as a whole and not per-flow.
Restrictions
• If a service profile includes an ISG traffic class configuration, the keepalive feature will be ignored.
•
If this feature is applied to a non-IP session, for example, a PPP over Ethernet (PPPoE) or PPP over
ATM (PPPoA) session, this feature application will fail and the following applies:
– If the feature is applied at a session-start event, both the feature application and the session will
fail.
–
If this feature is pushed onto a session after the session-start event, the push will fail.
SUMMARY STEPS
1. enable
2. configure terminal
3. policy-map type service policy-map-name
4.
keepalive [idle period1] [attempts max-retries] [interval period2] [protocol ICMP [broadcast] |
ARP]
5. exit
Step 2
debug command

• Enter the specific no debug command when you are
finished.
Step 3
end
Example:
Router# end
