Field Action/Description
Trunk Name Enter a unique alphanumeric name to identify the trunk.
Trunk Type Select the type of trunk backup services this trunk provides from
the pull-down list. Options include:
• Normal – Indicates that this trunk offers no backup service.
• Primary – Indicates that this trunk will act as the main trunk
connection in a backup service.
• Backup – Indicates that this is the trunk to which traffic will
be diverted in the event of primary trunk failure.
If you are configuring APS trunk backup for a CBX 500 or GX
550 switch, follow the instructions in “Configuring APS Trunk
Backup and Fast APS 1+1 for ATM Direct Trunks” on
page 7-29.
Administrative Cost
(1-65534)
Enter a value (from 1 - 65534) that defines the cost of using this
trunk for a VC when a VC is being dynamically created on the
switch.
Note: Modifying the value for this attribute does not bring down
the trunk or the associated logical port.
Keep Alive Error
Thresh (3-255)
Enter a value between 3 and 255 seconds to define the Keep
Alive (KA) error threshold. The default is 5 seconds. Service is
disrupted if you modify this value once the trunk is online.
