29-1 enable erps
Description
This command is used to enable the ERPS function on a switch. STP and LBD should be disabled
on the ring ports before enabling ERPS. ERPS cannot be enabled before the R-APS VLAN is
created, and ring ports, an RPL port, an RPL owner, are configured. In order to guarantee correct
operation, the following integrity will be checked when ERPS is enabled:
1. R-APS VLAN is created.
2. The Ring port is a tagged member port of the R-APS VLAN.
3. The RPL port is specified if the RPL owner is enabled.
4. The RPL port is not virtual channel.
5. The Ring port is the master port if it belongs to a link aggregation group.
Format

Parameters
None.
