Configuring EAPS Shared Ports
ExtremeWare XOS 11.1 Concepts Guide
285
Creating and Deleting a Shared Port
To configure a common link, you must create a shared port on each switch belonging to the common
link. To create a shared port, use the following command:
create eaps shared-port <ports>
where ports is the common link port.
NOTE
A switch can have a maximum of two shared ports.
To delete a shared port on the switch, use the following command:
delete eaps shared-port <ports>
Defining the Mode of the Shared Port
The shared port on one end of the common link must be configured to be the controller. This is the end
responsible for blocking ports when the common link fails thereby preventing the superloop.
The shared port on the other end of the common link must be configured to be the partner. This end
does not participate in any form of blocking. It is responsible for only sending and receiving health-
check messages.
To configure the mode of the shared port, use the following command:
configure eaps shared-port <ports> mode <controller | partner>
Configuring the Link ID of the Shared Port
Each common link in the EAPS network must have a unique link ID. The controller and partner shared
ports belonging to the same common link must have
matching link IDs. No other instance in the
network should have that link ID.
To configure the link ID of the shared port, use the following command.
configure eaps shared-port <ports> link-id <id>
Configuring the Shared Port Segment Timer
To configure the segment timer, use the following command:
configure eaps shared-port <ports> segment-timeout expiry-action [segment-down | send-
alert]
Where the following is true:
●
segment-down
—If the controller or partner switch’s segment timer expires, that segment is set to
“down,” and a query is not sent through the ring.
