ADC SWD4573I1 Manuale Utente

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 

 (command-line interface) or 

 (Web interface).
