Configuring an ERP Ring
•
If the ERP switch participates in an Ethernet OAM MaintenanceDomain(MD), configure the Manage-
ment Entity Group (MEG) level of the ERP service VLAN with the number that is used for the Ether-
net OAM MD.
•
The Service VLAN can belong to only one ERP ring at a time and must be a static VLAN. Note that
the service VLAN is also a protected VLAN.
Configuring an ERP Ring
The following configuration steps are required to create an ERP ring:
1
Determine which two ports on the switch are the ring ports. For example, ports 1/1 and 1/2.
2
Determine which VLAN on the switch is the ERP service VLAN for the ring. If the VLAN does not
exist, create the VLAN. For example:
-> vlan 500
3
Create the ERP ring configuration on each switch using the
following command configures an ERP ring with ring ID 1 on ports 1/2 and 1/2 along with service VLAN
500 and MEG level 1.
-> erp-ring 1 port1 1/1 port2 1/2 service-vlan 500 level 1
-> erp-ring 1 enable
To configure link aggregate logical ports as ring ports, use the erp-ring command with the linkagg param-
eter. For example:
-> erp-ring 1 port1 linkagg 1 port2 linkagg 2 service-vlan 500 level 1
-> erp-ring 1 enable
4
Repeat Steps 1 through 6 for each switch that participates in the ERP ring. Make sure to use the same
VLAN ID and MEG level for the service VLAN on each switch.
Use the
show erp
command to verify the ERP ring configuration. For more information about this
command, see the OmniSwitch CLI Reference Guide.
Removing an ERP Ring
To delete an ERP ring from the switch configuration, use the no form of the erp-ring command. For
example:
-> no erp-ring 1
Note. Administratively disable ring ports before deleting the ring to avoid creating any network loops.
Once a ring is deleted, then administratively enable the ports under Spanning Tree protocol.
Adding VLANs to Ring Ports
ERP allows a single VLAN or a number of VLANs to participate in a single ERP ring. The
untagged
command is used to tag the ring ports of the ERP ring with a VLAN ID.
