Configuring Redundant Ethernet Interfaces for Layer 2 Transparent Mode Chassis Clusters

On a device in a Layer 2 transparent mode chassis cluster, the redundant Ethernet interface is configured as a Layer 2 logical interface. Physical interfaces are bound to the parent redundant Ethernet interface. This topic describes how to configure the redundant Ethernet interface as a Layer 2 logical interface and how to bind physical interfaces (one from each node in the chassis cluster) to the redundant Ethernet interface.

In this example, you create a redundant Ethernet interface reth0 for redundancy group 1 and configure reth0 as an access interface with the VLAN identifier 1. Physical interfaces are then bound to reth0.

Note: Spanning-tree protocols are not supported for Layer 2 transparent mode in this release. You are responsible for ensuring that there are no loop connections in the deployment topology.

You can use either the J-Web or CLI configuration editor to configure a redundant Ethernet interface for a device in Layer 2 transparent mode.

This topic covers:

• J-Web Configuration
• CLI Configuration

J-Web Configuration

To configure a redundant Ethernet interface as a Layer 2 logical interface:

1. Select Configure>CLI Tools>Point and Click CLI.
2. Next to Interfaces, click Configure or Edit.
3. Next to Interface, click Add new entry.
4. In the Interface name box, enter reth0.
5. Next to Redundant ether options, click Configure.
6. In the Redundancy group box, enter 1.
7. Click OK to return to the Interface page.
8. Next to Unit, click Add new entry.
9. In the Interface unit number box, enter 0.
10. Under Family, click the Bridge check box, then click Configure.
11. For Interface mode, select Access.
12. From the VLAN ID list, select 1.
13. Click OK.

To assign a child physical interface on a chassis cluster node to the redundant Ethernet interface:

1. Select Configure>CLI Tools>Point and Click CLI.
2. Next to Interfaces, click Configure or Edit.
3. For the physical interface, click Edit.
4. Next to Gigether options, click Configure.
5. Next to Redundant parent, click Configure.
6. In the Parent box, enter reth0.
7. Click OK.
