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:
z
F4:
used in VPs.
z
F5:
used in VCs.
An ATM connection consists of a group of points. This OAM implementation
provides management for the following points:
z
Connection endpoint:
the end of a VP/VC connection where the ATM
cell are terminated.
z
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.
Select PVC:
Select the PVC channel you want to do the loop-back diagnostic.
Flow Type:
The ATM OAM flow type. The selection can be F5 Segment or F5
End-to-End.
Loopback Location ID:
The loop-back location ID field of the loop-back cell. The
default value is all 1s (ones) to indicate the endpoint of the segment or connection.
