Auto PVC Search
The overall operation of the auto-sensing PVC feature relies on end-to-end OAM
pings or packet discovery to defined PVCs. There are two kinds of PVCs: customer
default PVCs which are defined by the OEM/ISP and the backup PVCs. The backup
list of PVCs is of the following VPI/VCI:
0/35
,
8/35
,
0/43
,
0/51
,
0/59
,
8/43
,
8/51
, and
8/59
. We can add/delete VPI/VCI into the backup list. By clicking “Apply” button, the
auto-search mechanism can be enabled.
During connection establishment, the PVC module will first search the first customer
default PVC. If the first default PVC is found, the PVC module will stop this search. If
not found, the backup PVC list is used. If a PVC is found, the PVC module will update
the particular PVC as the first default PVC. If no PVC is found again, the module will
let the end-user know that no available VCC was found
.
With the connection established, the PVC is stored in flash as the connection default
PVC. Therefore upon reboot, this PVC is automatically chosen as the PVC for that
connection.
