Sets non-revertive mode for Ethernet Ring Protection (ERP).
Non-revertive mode is not set by default.
ERP configuration mode
After the Ethernet Ring enters a protected state, if you do not want the topology to return to the original state (even after the failure has cleared) you can use the non-revertive-mode command. Run this command on the RPL owner only, and then run the enable command.
This command is allowed only on the RPL-owner node. An error message is issued if it is executed on another node.
Use the no form of this command to return the default.
The following example configures non-revertive mode and enables the configuration.
device# configure terminal device(config)# erp 1 device(config-erp-1)# non-revertive-mode device(config-erp-1)# enable
