Assigning Backup Ports and Port Priority to the Circuit

Each circuit contains one primary port and several additional ports that serve as
backups. If the primary port fails, the redundancy path will switch to the first
backup port specified, and as necessary, switch to subsequent backup ports in the
order in which they were specified. The maximum number of ports that can be
configured for a circuit is eight.
As noted above, you will use the altered Chassis View display to assign ports to
your redundant circuit. The port you designate as primary will turn green; the
remaining backup ports will display in gray. Once redundancy is enabled,
whichever port is the current active link in the redundant circuit will display in
green.
To select the primary and backup paths for the designated circuit:
1. In the altered Chassis View window
2. Select Primary. The port will be designated as "PRI," and the port box will turn
3. Click on the port that you wish to specify as the first backup port. Again, the
4. Select Backup. The port will be designated as "BKP," and will remain gray.
5. To specify further backup ports, repeat steps 3 and 4. Be sure to specify each
The first port you specify will remain the default active link, even if you designate
that port as a backup and designate a different port as primary. If you wish to
ensure that the primary port will be the first active port in the circuit, you can use
the Activate command from the port menu to override the firmware default. See
