ETHERNET PROTECTION SWITCHED RING (EPSRING™) COMMANDS
EPSR
PRIORITY
epsr priority
Overview This command sets the priority of an EPSR instance on an EPSR node. Priority is
used to prevent “superloops” forming under fault conditions with particular ring
configurations. Setting a node to have a priority greater than one, also has the
effect of turning on superloop protection.
The no variant of this command returns the priority of the EPSR instance back to its
default value of 0, which also disables EPSR Superloop prevention.
Syntax
epsr <epsr-instance> priority <0-127>
no <epsr-instance> priority
Default The default priority of an EPSR instance on an EPSR node is 0. The negated form of
this command resets the priority of an EPSR instance on an EPSR node to the
default value.
Mode EPSR Configuration
Example To set the priority of the EPSR instance called blue to the highest priority (127),
use the command:
awplus(config-epsr)# epsr blue priority 127
To reset the priority of the EPSR instance called blue to the default (0), use the
command:
awplus(config-epsr)# no epsr blue priority
