G.8032 ETHERNET RING PROTECTION SWITCHING COMMANDS
ERP
-INSTANCE
erp-instance
Overview Use this command to enable or disable a G.8032 Ethernet Ring Protection (ERP)
instance.
Syntax
erp-instance {enabled|disabled}
Default The ERP instance is disabled.
Mode G8032 Configure Switch
Usage notes Once a G.8032 ERP instance has been configured with the correct parameter
settings or defaults, it can be enabled to run the G.8032 protocol. To change
certain ERP instance parameters, the instance may need to be disabled.
When enabled, the instance is restarted back to the G8032_ST_INIT state. In this
state, if the node has an RPL-Owner or RPL-Neighbor port, it will be blocked.
Otherwise the node will block one of its ring ports. All the nodes will send
Ring-Automatic Protection Switching (R-APS) messages initially. The G.8032
protocol and state machines will transition the ring into another more appropriate
state.
When disabled, the ERP instance will no longer process incoming R-APS messages
for that instance, nor send any R-APS messages. The raps-channel VLAN and any
data-traffic VLANs used by this instance will be put in the forwarding state for its
physical ring ports. Caution should be taken to avoid loops when disabling an ERP
instance.
Example To enable an ERP instance named “blue”, use the following commands:
awplus(config)# g8032 erp-instance blue
awplus(g8032-config-switch)# erp-instance enabled
