Appendix A Command Reference
rpr-ieee keepalive-timer interval [east | west]
Use this command to configure the keepalive timer configuration on a specific IEEE 802.17b based RPR
span (east or west).
Syntax Description Parameter
east
west
interval
Defaults
The default is 1 second.
Command Modes IEEE 802.17b based RPR interface configuration
Usage Guidelines If a station does not receive fairness frames from its neighboring stations in the ring, the keepalive timer
value determines how much time will elapse before a protection event is triggered. The keepalive timer
works in tandem with the SONET holdoff timer. You would lengthen both of these timer intervals to
avoid double hits when IEEE 802.17b based RPR is running over a SONET-protected network.
Examples In this example, interface is shortened to int.
router(config)# int rpr-ieee 0
Router(config-if)# rpr-ieee keepalive-timer 100 east
