20.1.5 Running the OAM Ping Test

The Operation and Maintenance (OAM) ping test checks the status of a Virtual Channel
(VC) of the Asynchronous Transfer Mode (ATM) connection to the remote Network Access
Concentrator (NAC). Each of the ATM's virtual channels has an address that consists of a
Virtual Path Indicator (VPI) and Virtual Channel Indicator (VCI). The OAM ping test sends a
request, either a VP loopback (F4) or a VC loopback (F5), and receives a reply from the
NAC at the other end of the ATM connection.
The procedure below describes how to run an OAM Ping test in the 'Diagnostics' screen.
This test is done under the OAM Ping group.

To run an OAM ping test:
1. From the 'Type' drop-down list, select the type of OAM ping to run:
•
F4 End-to-End
•
F4 Segment
•
F5 End-to-End
•
F5 Segment
2. In the 'VPI' field, enter the channel's VPI value.
3. In the 'VCI' field, enter the channel's VCI value. This is applicable only if you are
checking the VC loopback (F5).
4. In the 'Count' field, enter a number of the ping packets sent to the destination address.
5. Click Go; in a few moments, diagnostic statistics is displayed. If no new information is
displayed, click Refresh.
