To add a VLAN or range of VLANs to ring ports use the vlan members untagged command.
-> vlan 12-20
-> vlan 12-20 members port 1/1 tagged
-> vlan 12-20 members port 1/2 tagged
Configuring an RPL Port
A ring protection link (RPL) port can be a physical or logical port. The port must be a ring port before it is
configured as an RPL port, and out of the two ring ports on the node, only one can be configured as a RPL
port. The RPL remains blocked to prevent loops within the ERP ring.
To configure an RPL port, first disable the ring and then use the erp-ring rpl-node command to specify
which ring port serves as the RPL. For example:
-> erp-ring 1 disable
-> erp-ring 1 rpl-node port 1/1
-> erp-ring 1 enable
Note. RPL node can be configured only when the ring is disabled; RPL configuration applied to the ring
while it is enabled is rejected.
To remove the RPL node configuration for the specified ring, use the no form of the erp-ring rpl-node
command. For example:
-> no erp-ring 1 rpl-node
To verify the RPL node configuration for the switch, use the show erp command. For more information
about this command, see the OmniSwitch CLI Reference Guide.
Setting the Wait-to-Restore Timer
The wait-to-restore (WTR) timer determines the number of minutes the RPL owner waits before blocking
the RPL port after the ERP ring has recovered from a link failure.
By default, the WTR time is set to five minutes. To change the value of the WTR timer, use the erp-ring
wait-to-restore command. For example:
-> erp-ring 1 wait-to-restore 6
The above command is only used on a switch that serves as the RPL node for the ERP ring. The specified
ERP ring ID must already exist in the switch configuration.
To restore the timer back to the default setting, use the no form of the erp-ring wait-to-restore command.
For example:
-> no erp-ring 1 wait-to-restore
To verify the WTR configuration, use the show erp command. For more information about this command,
see the OmniSwitch CLI Reference Guide.
