TitleWhat is the easiest way to add additional vlans to existing EAPS rings?
Question
What is best practice when adding additional vlans to existing EAPS domains?
Environment
Summit
Black Diamond 8810 / X8
EXOS All
EAPS
Answer
The following procedure is based on avoiding accidental loops that can be created when adding the vlans to existing rings:

1) Create the new vlans and add a 802.1q tag to the vlan (Do NOT add eaps rings ports to these vlans yet)
2) Add the newly created vlans to the EAPS domain(s) as protected. (Ignore warning message)
3) Once all the vlan(s) are added to the nodes in the EAPS domain, add the EAPS ring ports to the vlan as tagged starting first on the Master node in the ring.
4) If there is an EAPS shared port implemented, add the segment ports to vlans as tagged on the controller and partner.  Skip this step if no shared port / common link involved.
5) Confirm that the protected vlan is added in the domain on each EAPS node, the ring is complete from the Master node, the secondary port on the EAPS master is in "blocking" state, and that there is no looping in the network via the "top" command.
