Configuration Process

Configuration Process

The key to configuring Ethernet ring protection switching (ERPS) for an Ethernet ring network is creating Ethernet ring protection (ERP) instances.

Figure 4-1 Process of configuring ERPS
Table 4-1 Procedure for configuring a ERPS
Step Operation Description
1 Creating Ethernet Ring Protection Instances

Required. Set the major parameters as follows:

  • Set ERPS ID, East Port, West Port, ERP Ring Node Flag, Flag Port, and Control VLAN according to the network plan.
  • When setting ERP Ring Node Flag, note the following:
    • An ERP ring has only one ring protection link (RPL) owner node.
    • For an ERPS V1 protection instance, set ERP Ring Node Flag to RPL Port for the RPL owner node on an ERP ring and to None for other nodes on the ring.
    • For an ERPS V2 protection instance, you also need to set the neighbor port and the next neigbor port.
  • Set Control VLAN to a value different from the VLAN IDs of Ethernet service packets.
2 Setting Protocol Parameters for an ERPS Instance


  • ERPS V1-based instance required. Set Compatible_Version to ver1.
  • If ring automatic protection switching (R-APS) virtual channels are required by sub-ring instance, set Virtual Channel Status to Enable (default) and set Virtual Channel VLANs according to the network plan. If R-APS virtual channels are not required, set Virtual Channel Status to Disable.
3 Setting Global ERPS Protocol Parameters


It is recommended that you set parameters to default or planned values.

4 Creating a Virtual Channel VLAN Forwarding Table


Set parameters according to the network plan.

  • The control VLAN ID of an R-APS virtual channel must be different from the VLAN IDs of the services carried by the same ERP ring.
  • The control VLAN ID of an R-APS virtual channel must be different from the control VLAN ID of the R-APS channel on the same ERP ring.
