Configuring the Ring Ports

Each node on the ring connects to the ring through two ring ports. The ports that you choose on each switch should be tagged and added to the control VLAN and all protected VLANs. For information on adding tagged ports to a VLAN, see VLANs.

On the master node, one ring port must be configured as the primary port, and the other must be configured as the secondary port.

We recommend that you keep the loop protection warning messages enabled. If you have considerable knowledge and experience with EAPS, you might find the EAPS loop protection warning messages unnecessary.

To configure a node port as primary or secondary, use the following command:
configure eaps name [primary | secondary] port ports
If you attempt to add an EAPS ring port to a VLAN that is not protected by EAPS, the default switch configuration prompts you to confirm the command with the following message:
```
Make sure <vlan_name> is protected by EAPS. Adding EAPS ring ports to a VLAN could cause a loop in the network. Do you really want to add these ports (y/n)
```
When prompted, do one of the following:
- Enter y to identify the switch as a transit node.
- Enter n or press [Return] to cancel the command.
