OAM Alarms and Loopbacks
Checklist
Use the following as a checklist of information or processes needed to perform OAM
ATM-layer loopback tests:
•
Pre-configure all Avidia systems and ATM switches with an OAM Location ID.
•
Ensure that all links and loops under test are operational.
•
Ensure that the PVC(s) under test are correctly defined and operational at every hop in the
test path.
•
When originating the OAM loopback test from an Avidia system, know the slot, port, VPI,
and VCI values.
•
Have values identified for the OAM cell count, timeout, and delay.
These optional values you can set up for the OAM ATM-layer loopbacks are:
–
count which is the total number of OAM cells to be sent
–
timeout value which is how long the source waits for a cell to be returned from the
destination before indicating a failure
–
delay which is the number of seconds the system waits between transmitting
OAM cells
•
Determine if an SNMP Trap should be sent when the OAM loopback test is completed.
Run the OAM loopback using the section
page 342
(command-line interface) or
page 558
(Web interface).
