Redundant Link Control
The Redundant Link Control menu allows configuring up to 24 pairs of
redundant links. A redundant pair consists of any two physically linked
ports in the stack, where one is the primary link port and the other is the
secondary link port. The primary link is the active link between two
devices and the secondary is a backup and is set to inactive to prevent
looping. In the event that the primary link fails, the secondary link
becomes active. The secondary link stays active even if the primary link
recovers. You must manually reset the primary link status to active in
order to re-instate the redundant pair.
Redundant Link Control
You configure a primary link by assigning a specific port on a specific
hub to a Link Pair Index. You assign a secondary link by assigning a
specific port on a specific hub to the same Link Pair Index.
Link Pair Index: The number identifying the redundant link
pair. (1 to 24)
Primary Link Group: This object identifies the hub ID of the
primary link for a given redundant link pair.
