g8032 forced-switch erp-instance
Overview Use this command to force a protection switch on a G.8032 Ethernet Ring
Protection (ERP) instance ring port.
Syntax g8032 forced-switch erp-instance < erp-instance-name >
{east-interface|west-interface|terminating-interface}
Mode Privileged Exec
Usage G.8032 supports a Forced Protection Switch action initiated by the operator. A
Forced Protection Switch command is to be issued at a given G.8032 node and
given port in the ring. This results in a block being applied at that ring port (and an
unblock on the opposite ring port), and a R-APS designated Forced Switch
message to flow around the ring causing the RPL to become unblocked.
Multiple Forced Switch actions can take place along a G.8032 ring. Care must be
taken when using the Force Switch command as it can only be undone by issuing
a Clear command and not by a failure nor the clearing of a failure. If a node that was
issued a Force Switch command later fails, then it becomes difficult to remove the
Force Switch condition from the ring. In this situation, the operator has to go to the
nodes that are adjacent to the failed node, and for each one, issue a Forced Switch
command on the ring link facing the failed node followed by a Clear command.
If the G.8032 Physical Ring instance associated with the specified ERP instance is
set to terminating-interface, then only one ring port is available and
terminating-interface must be used in this command, otherwise specify the
east-interface or the west-interface.
To clear this action command, use the clear g8032 erp-instance command.
Example To issue a Forced Protection Switch on the East interface of an ERP instance named
“blue”, use the following command:
awplus# g8032 forced-switch erp-instance blue east-interface
