• 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.
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 will become the ring ports. For example, ports 1/2 and 3/1.
2 Administratively disable the VLAN that will serve as the default VLAN for the ring ports if the switch
is operating in the flat Spanning Tree mode without MSTP. For example, if VLAN 10 is the default
VLAN for ports 1/2 and 3/1, before configuring 1/2 and 3/1 as a ring ports, disable VLAN 10.

VLAN for ports 1/2 and 3/1, before configuring 1/2 and 3/1 as a ring ports, disable VLAN 10.
-> vlan 10 disable
3 Disable Spanning Tree on the ports that will become the ring ports if the switch is operating in the flat
Spanning Tree mode and using RSTP. For example, disable the Spanning Tree for the VLAN 10 port 1/2
instance and VLAN 10 port 3/1 instance:
Spanning Tree mode and using RSTP. For example, disable the Spanning Tree for the VLAN 10 port 1/2
instance and VLAN 10 port 3/1 instance:
-> bridge 10 1/2 disable
-> bridge 10 3/1 disable
4 Determine which VLAN on the switch will become the ERP service VLAN for the ring. If the VLAN
does not exist, create the VLAN. For example:
does not exist, create the VLAN. For example:
-> vlan 500
5 Determine the APS Management Entity Group (MEG) level number to assign to the service VLAN. If
the ERP switch participates in an Ethernet OAM MaintenanceDomain(MD), configure the MEG level
with the same number used for the Ethernet OAM MD.

with the same number used for the Ethernet OAM MD.
6 Create the ERP ring configuration on each switch using the
command. For example the
following command configures an ERP ring with ring ID 1 on ports 1/2 and 3/1 along with service VLAN
1001 and MEG level 2.
1001 and MEG level 2.
-> erp-ring 1 port1 1/2 port2 3/1 service-vlan 500 level 2
-> 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:
eter. For example:
-> erp-ring 1 port1 linkagg 1 port2 linkagg 2 service-vlan 1001 level 2
-> erp-ring 1 enable
7 Repeat Steps 1 through 6 for each switch that will participate in the ERP ring. Make sure to use the
same VLAN ID and MEG level for the service VLAN on each switch.
same VLAN ID and MEG level for the service VLAN on each switch.
Use the
command to verify the ERP ring configuration. For more information about this
command, see the OmniSwitch CLI Reference Guide.
