Appendix A Command Reference
rpr-ieee protection sonet holdoff-timer interval {east | west}
Use this command to configure the SONET hold-off timer for a protection event on the specified
IEEE 802.17b based RPR span. Use the no form of this command to turn off the SONET holdoff timer.
This command replaces the pos vcat defect {delayed | immediate} command.
Note
Syntax Description Parameter
east
west
interval
Defaults The default value is 0 milliseconds.
Command Modes
IEEE 802.17b based RPR interface configuration
Usage Guidelines This command is used to allow the slower SONET protection mechanisms to take effect ahead of
IEEE 802.17b based RPR protection. The SONET holdoff timer works in tandem with the keepalive
timer. You could lengthen both of these interval values to avoid double hits when RPR-IEEE is running
over a SONET-protected network.
In this command, protection can be shortenened to prot.
Examples
In this example, interface is shortened to int.
Router(config)# int rpr-ieee 0
Router(config-if)# rpr-ieee prot sonet holdoff-timer 2
Related Commands rpr-ieee keepalive-timer
Description
Pertains to configuration for eastbound span traffic.
Pertains to configuration for westbound span traffic.
Timer interval expressed in milliseconds. Value is a multiple of
10 milliseconds in the range of 0 to 200 milliseconds (for example,
interval 2 sets the holdoff timer to 20 milliseconds.
