Smart Pair Configuration
A Smart Pair consists of two ports which are paired to provide layer 2 link
redundancy, The pair consists of a primary port and a backup port. All traffic is
forwarded through the primary port and the backup port will be set to standby. If
the primary port link goes down, the backup port is activated and all traffic is
forwarded through it. If the primary port recovers, all traffic will again be forwarded
through the primary port after a configured delay. (wait-to-restore delay).
Under the Administration > Smart Pair menus you can configure the Smart Pair
ports and set the wait to restore delay for a globally configured Smart Pair.
Additionally you can show the Smart Pairs configured on the switch and in the
show menu restore traffic manually to a configured Smart Pair.
Usage Guidelines
Spanning-Tree must be disabled on the port in order to configure it as part of a
Smart Pair.
A configured backup port can only be a member of a single Smart Pair.
Dynamic trunk ports cannot be configured as a Smart Pair port (only static
trunk ports).
When a trunk group is identified as a backup port of a Smart Pair, any members
removed from the trunk group will not retain the Smart Pair settings.
When all members of trunk group set as a backup port are removed, the
backup port is also removed.
The VLAN mode of the backup port should not be changed after it is
configured otherwise the behavior becomes unpredictable.
