Clearing Local Fdl Statistics For A Channel; Changing Atm Pvc Oam Parameters; Enabling Oam Loopback - Nortel Versalar 15000 Troubleshooting Manual

Managing and Troubleshooting the Versalar Switch Router 15000

Clearing Local FDL Statistics for a Channel

To reset the FDL statistics to 0, go to the T1 test prompt (for example,
t1-test/t1-2/1/4
clear-fdl-stats {no-action
no-action
clear-stats
The following example shows how to reset the FDL statistics to 0 on slot 2,
connector 1, FT1 channel 5:
t1-test/2/1/5#
t1-test/2/1/5#

Changing ATM PVC OAM Parameters

On the Versalar 15000, Operations and Management (OAM) provides a
mechanism by which ATM devices can receive prompt notification of permanent
virtual circuit (PVC) failures. OAM uses special loopback cells or alarms to detect
PVC failures. These mechanisms decrease the amount of time between an actual
PVC failure and when the router is aware of this failure. When using OAM
loopback cells, the time can decrease to only a few seconds; when using OAM
alarms, the detection is almost instantaneous.

Enabling OAM Loopback

To enable OAM loopback, you must enable loopback on the PVC and define the
interval and thresholds for loopback detection and control.
Note: For OAM loopback to function properly, you must configure it on all
PVCs on an interface. Link status is based on the OAM loopback status of all
PVCs on the interface.
The OAM loopback feature specifies whether or not the ATM PVC sends OAM
loopback cells. By default, OAM loopback is disabled. However, you can enable
and disable OAM loopback at any time.
