The primary and all of its backup DLCIs in the non-initiating
node must be on the same RLP.
Switchover Timer
is the time the initiating node will wait after detecting a primary DLCI failure before
it checks for available backups.
Switchback Timer
is the time the initiating node will wait before switching from the backup to the
primary DLCI after the primary becomes active again. If set to the maximum of
65565
,
the backup will not switch to the primary unless it (the backup) fails.
Time to Hold Data While Waiting
is the time the node will queue data while waiting for a backup DLCI to become
active. If neither a backup nor the primary has not become active when this timer
expires, the data will be discarded.
Configuring Frame Relay PVCs Across the Node
An FRX4000 or FRX6000 PVC is a "permanent" connection between two physical
ports in a node. This allows communication between the attached devices as soon as
they are powered up, without the need to first establish a connection.
To display a list of current PVCs, press
[A]
at the PVC Configuration Menu (or
[A], [D],
[E], [A]
from the Main Menu). The display will list PVCs of all supported types: frame
relay, X.25, async, and async-to-X.25.
To add or change a PVC, press
[B]
at the PVC Configuration Menu and enter a 1–4
digit
Connection ID
, which is simply a number unique to this connection, that identifies
the PVC.
