OAM Alarms and Loopbacks
60 Avidia System Configuration and Management User Manual
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 “Configuring and Initiating OAM Loopbacks” on
page 342 (command-line interface) or “Configuring and Initiating OAM Loopbacks” on
page 558 (Web interface).
