4.8.2 ATM Loopback

In order to isolate the ATM interface problems, you can use ATM OAM loopback cells to verify

connectivity between VP/VC endpoints, as well as segment endpoints within the VP/VC. ATM

uses F4 and F5 cell flows as follows:

í F4: used in VPs

í F5: used in VCs

An ATM connection consists of a group of points. This OAM implementation provides

management for the following points:

í Connection endpoint: the end of a VP/VC connection where the ATM cell are

terminated

í Segment endpoint: the end of a connection segment.

This page allows you to use ATM ping, which generates F5 segment and end-to-end

loop-back cells to test the reach-ability of a segment endpoint or a connection endpoint.
