rpr-ieee protection wtr-timer {interval | never}
rpr-ieee protection wtr-timer {interval | never}
Use this command to configure the amount of time that an IEEE 802.17b based RPR span stays in
wait-to-restore (WTR) state before normal service is restored on a span. The never argument configures
an RPR-IEEE span WTR timer to disallow the WTR function.
Syntax Description Parameter
interval
never
Defaults The default value is enabled, and the default interval is 10 seconds.
Command Modes IEEE 802.17b based RPR interface configuration
Usage Guidelines
This command can be used to moderate an IEEE 802.17 RPR span that repeatedly changes into and out
of a protected state. It is provisioned similarly to the WTR timer used in SONET protection schemes.
Use the no argument to configure a span not to go through a WTR period before restoring service during
a protection event.
In this command, protection can be shortened to prot.b based
Examples
In this example, interface is shortened to int.
Router(config)# int rpr-ieee 0
Router(config-if)# rpr-ieee prot wtr-timer 50
