Command Usage
◆ Before enabling a ring, the global ERPS function should be enabled with the
erps command, the east and west ring ports configured on each node with the
ring-port command, the RPL owner specified with the rpl owner command,
and the control VLAN configured with the control-vlan command.
◆ Once enabled, the RPL owner node and non-owner node state machines will
start, and the ring will enter idle state if no signal failures are detected.
Example
Console(config-erps)#enable
Console(config-erps)#
