AIS-RDI settings
Enable AIS-RDI
Detection
When selected, alarm indication signal (AIS) cells and remote defect
indication (RDI) cells are used to report connectivity failures at the ATM
layer of the PVC.
When deselected, AIS/RDI cells are disabled.
AIS cells notify downstream devices of the connectivity failure. The last
ATM switch then generates RDI cells in the upstream direction towards the
device that sent the original failure notification.
Down Count The number of consecutive AIS/RDI cells that cause the PVC to go down.
Valid values range from 1 to 60. The default is 1.
Up Count The number of seconds after which a PVC is brought up if no AIS/RDI cells
are received. Valid values range from 3 to 60 seconds. The default is 3.
Segment Continuity Check settings
Enable Segment
Continuity Check
When selected, OAM F5 continuity check (CC) activation and deactivation
requests are sent to a device at the other end of a segment.
When deselected, segment CC activation and deactivation requests are
disabled.
Note If Configure Continuity Check is deselected in the OAM-PVC tab,
these settings are saved in the device configuration but are not
applied.
Activation Count The maximum number of times that the activation request is sent before the
receipt of an acknowledgement. Valid values range from 3 to 600. The
default is 3.
Deactivation Count The maximum number of times that the deactivation request is sent before
the receipt of an acknowledgement. Valid values range from 3 to 600. The
default is 3.
Retry Frequency The interval between activation/deactivation retries, in seconds. The default
is 30 seconds.
