Configuring the STP Protected VLAN as an EAPS Protected VLAN

Configure the data VLAN (currently protected by STPas an untagged VLAN) as an EAPS protected VLAN.
  1. Assign an 802.1q tag to the data VLAN, as this might not be required with the previous STP configuration.
  2. Next, the data VLAN is added to the EAPS domain as a protected VLAN.
  3. Configure the VLAN port changes at the end to prevent any broadcast loop from forming during the transition from STP to EAPS protection.
    A warning message is displayed on the CLI, but this can be ignored, as it is just a reminder that the ring ports have not been added to the protected VLAN yet.
  4. Change the port membership for the data VLAN from untagged to 802.1q tagged trunk ports.
