Ethernet Protection Switching Ring (EPSR)

purge epsr

Syntax PURge EPSR

Description This command destroys all EPSR instances, returning the EPSR module to its status when it is first powered on.

Warning If the data VLANs of any EPSR instances are still configured in a ring formation, purging EPSR could cause a loop in the network. To avoid creating loops, take one or more of these steps before running this command:

■disable the ports, using the disable switch port command.

■unplug the ports.

■delete the ports from the VLAN, using the delete vlan port command.

Examples

To purge all EPSRs, use the command:

pur epsr

Related Commands create epsr show epsr
