Reset – Resets the ATM Destination Segment ID for the VCC. When selected, all octets in this segment are set to FF, as shown in the screen example.
Select or Enter . . .
From the VCCs configured for the ATM link.
EndtoEnd – For Operations, Administration, and Maintenance (OAM) functions.
The device defaults to this type of loopback.
Segment – For OAM functions, a segment loopback will be performed on the selected VCC on the link.
￿ATM Segment ID for the loopback destination – The ID must be entered in 16 byte values, 2 hexadecimal characters each, separated by colons.
– The first byte must be 00, 01, 02, 03, or FF.
– If the first octet is FF, octets 2–16 must also be FF.
– If the first octet is 00, octets 2–16 must also be 00.

￿NOTE: Destination Segment ID and Reset do not appear if Loopback Type is EndtoEnd instead of Segment.

ATM PingStart or Stop commands begin or end the test.

The following messages can appear on line 24:

If an ATM Location ID has not yet been configured, Loopback Type is set to

￿Segment, an ATM Ping is started, and an ATM Location ID must be configured message is displayed.

If the device is already performing an ATM Ping, an Invalid – Was Already Active message is displayed.

If any physical test is active on the interface when the ATM Ping was started,

￿the Invalid Test Combination message is displayed.

If the ATM link is not active when the ATM Ping is started, the Link Inactive message is displayed.

This test cannot be run when a physical test is already active on the interface, and no physical test can be run on the interface when the ATM Loopback is active on the interface.
