Configure the Ethernet Protection Ring (ERP) to ensure reliable and efficient operation of Ethernet networks in ring topologies.

This task configures the Ethernet Ring Protection (ERP) to ensure reliable and efficient operation of Ethernet networks in ring topologies.

The Ethernet Ring Protection (ERP) ensures reliable and efficient operation of Ethernet networks in ring topologies. Follow the procedure given here to configure ERP.

Procedure

1.

Use the ethernet ring g8032 ring-name command to specify the Ethernet ring and enter Ethernet ring port configuration mode.

Example:

Device(config)# ethernet ring g8032 g8032_ring
2.

Use the port0 interface type number command to connect port0 of the local node to the Ethernet ring and enter Ethernet ring protection mode.

Example:

Device(config-erp-ring)# port0 interface GigabitEthernet1/3

Use the exit command to enter the Ethernet ring port configuration mode.

Example:

Device(config-erp-ring-port)# exit
3.

Use the port1 interface type number command to connect port1 of the local node of the interface to the Ethernet ring and enter the Ethernet ring protection mode.

Example:

Device(config-erp-ring)# port1 interface GigabitEthernet1/4

Use the exit command to enter the Ethernet ring port configuration mode.

Example:

Device(config-erp-ring-port)# exit
4.

Use the instance instance-ID command to assign the Ethernet service instance to monitor the ring port (port0) and detect ring failures.

Example:

Device(config-erp-ring)# instance 1

(Optional) Use the profile profile-name command to specify the Ethernet ring profile.

Example:

Device(config-erp-inst)# profile g8032-profile

The default profile is automatically applied, if no profile is specified.
5.

Use the RPL {port0 | port1}{owner | neighbor } command to specify the Ethernet ring port on the local node as the RPL owner or neighbor.

Example:

Device(config-erp-inst)# rpl port0 owner

Specify the RPL port connected to both the owner and neighbor nodes. These nodes must be adjacent and directly connected by a single link. RPL port configuration is required for both the owner and neighbor nodes, while it is not needed for a normal node. By default, each node is considered a normal node.
6.

Use the inclusion-list VLAN-ids VLAN-ID command to specify the VLANs that are managed (traffic management) by the Ethernet ring protection mechanism.

Example:

Device(config-erp-inst)# inclusion-list vlan-ids 10, 100-200

For VLAN-ID, use a list or individual VLAN IDs in the format a-b or c, where a-b denotes a range and c represents a single VLAN ID.
7.

Use the APS-channel command to enter Ethernet ring instance APS-channel configuration mode.

Example:

Device(config-erp-inst)# aps-channel

The APS channel allows control and coordination messages to flow between nodes or devices to ensure the protection mechanism operates correctly and efficiently.
8.

(Optional) Use the level level-value command to specify the APS message level for the node on the Ethernet ring.

Example:

Device(config-erp-inst-aps)# level 1

The APS message level ranges from 0 (lowest) to 7 (highest).
9.

Use the control VLAN VLAN-ID command to define a control VLAN dedicated to carrying APS messages within the network.

Example:

Device(config-erp-inst-aps)# control vlan 10

The control VLAN should not be used for any other purpose.

The valid VLAN-ID range is 1 to 4094.
