Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Configuration Guide
Release 5.0.10, OL-3845-01 Rev. B0, August 16, 2004
Chapter 3 Provisioning PXM1E Communication Links
General PXM1E Configuration Procedures
Note
Modifying any of the attributes causes the IMA group to restart.
In the following example, the user modifies the transmit frame length, the IMA group uptime, and the
IMA group downtime:
M8830_CH.1.PXM.a >
cnfimagrp
-grp 2.1 -txfl 128 -uptim 100 -dntim 100
Step 5
To verify IMA group configuration changes, enter a dspimagrp command for the appropriate IMA
group.

-mode <autoRestart>
The -mode parameter is optional and configures the IMA autorestart feature.
The parameter options and the numbers that select them are:
•
Disable autorestart for this IMA group = 1
•
Enable autorestart for this group and relearn the receive IMA ID during
autorestart = 2
•
Enable autorestart for this group and use the previously learned receive
IMA ID during autorestart = 3
Note
Before configuring the -mode option, you must enable IMA
autorestart for the card using the cnfimaparms command.

Chapter 9, “Switch Operating Procedures.”
-rxid
<rxImaIdExpected>
This optional parameter defines the receive IMA ID expected. This number
should match the transmit IMA ID (txid) configured at the far end of the IMA
link. A configured value of -1 (minus one) specifies that the IMA group
should learn the far end ID on restart. The range is -1 to 255.

in
Chapter 9, “Switch Operating Procedures.”
