enable erps
Description
This command is used to enable the global ERPS function on a Switch. When both the global state
and the specified ring ERPS state are enabled, the specified ring will be activated.
The global ERPS function cannot be enabled, when any ERPS ring on the device is enabled and
the integrity of any ring parameter is not available. For each ring with the ring state enabled when
ERPS is enabled, the following integrity will be checked:
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 specified as virtual channel.
