Configuring the STP Protected VLAN as an EAPS Protected VLAN
- Assign an 802.1q tag to the data VLAN, as this might not be required with the previous STP configuration.
- Next, the data VLAN is added to the EAPS domain as a protected VLAN.
-
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.
-
Change the port membership for the data VLAN from untagged
to 802.1q tagged trunk ports.
