Each command is listed, in detail, in the following sections.
enable erps
Purpose
Used to enable the global ERPS function on a switch.
Syntax
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.
The default state is disabled.
Parameters
None.
Restrictions
Only Administrator and Operator-level users can issue this command.
