Managing Loopbacks
Step 3 Enter the stopimalnktst <group> command to stop the IMA link test that was started with the
startimalnktst command.
Step 4 Replace <group> with the number of the IMA group that owns the link that is being tested, in format
bay.group.
In the following example, the user stops an IMA link test that is running on bay 1, group 1:
MGX8850.2.AXSME.a> stopimalnktst 1.1
Modifying an IMA Link Test
To modify an IMA test link or IMA test pattern after the test has been started, enter the cnfimalnktst
command as follows:
cnfimalnktst -grp <group> -lnk <link> -pat <testPat>
Replace <group> with the number of the IMA group that owns the link whose test you want to modify,
in format bay.group. Replace <link> with the number of the IMA link whose test you want to modify,
in the format bay.link. Replace <test Pattern> with the number of the transmit test pattern you want to
modify, in the range from 0 through 254.
In the following example, the user changes the link to 3 and the test pattern to 2 on IMA group 1.1:
MGX8850.2.AXSME.a> cnfimalnktst 1.1 3 2
Managing Loopbacks
The AXSM cards support line and channel loopbacks.
Line loopbacks can be enabled by:
• Manually placing the line in loopback mode using AXSM CLI commands
• Enabling loopback code detection using AXSM CLI commands
Channel loopbacks are enabled through use of the following CLI commands on the AXSM cards:
• addlnloop—Add local or remote loopback, or remove loopback from a line.
• dellnloop—Delete local or remote loopback.
For more information on the use of these commands, see Chapter 5, “AXSM Command Reference.”
