Description
This command displays both admin value and operational value of ring port. The admin value is the
latest user configuration. The operational value is actual running configuration. Sometimes, modifying
a ring needs more than one command. Before user configure complete, the current configuration may
invalid. In this case, to avoid temporary loop, user configuration will not apply to state machine
immediately. The ERPS will run protocol by previous configuration which is valid. If the admin value is
different from the operational value, it means that the new configuration is not applied.
Both RPL port and RPL owner have admin value and operational value, the reason is same as ring
port.
If ERPS function is disabled on a ring, the admin value of this ring shall be applied to operational value
immediately.
If ERPS function is enabled on a ring, the admin value of this ring can be applied to operational value
only when all of follow conditions are satisfied:
1. The Ring port is a tagged member port of the R-APS VLAN.
2. The RPL port is specified if the RPL owner is enabled.
3. The RPL port is not virtual channel.
4. The Ring port is the master port if it belongs to a link aggregation group.
The save function will record the operational value if the operational value is different form the admin
value.
