ETHERNET PROTECTION SWITCHED RING (EPSRING™) COMMANDS
EPSR
STATE
epsr state
Overview This command enables or disables an EPSR instance.
Syntax
epsr <epsr-instance> state {enabled|disabled}
Mode EPSR Configuration
Usage notes In a super-loop protection scenario, if you have:
• a device on the common segment acting as the master node for multiple
EPSR rings,
• and you disable the rings and later re-enable them (e.g., when doing EPSR
configuration changes),
• then you must re-enable the ring with the highest EPSR SLP priority last.
If you do not re-enable the rings in that order, the primary port may end up
permanently in a blocking state. If the primary port does end up in a permanent
blocking state, recover by disabling and re-enabling the EPSR ring that has the
highest priority.
Example To enable the EPSR instance called ‘blue’, use the command:
awplus(config-epsr)# epsr blue state enabled
