Step 4 To configure an IMA group, enter the cnfimagrp command, as shown in the following example:
M8830_CH.1.PXM.a > cnfimagrp <-grp <group> [-ver <version>] [-txm <minLinks>] [-txid
<txImaId>] [-txfl <txFrameLen>] [-dd <diffDelayMax>] [-uptim<groupUpTime>] [-dntim
<groupDownTime>] [-vfb <verFallback>] [-mode <autoRestart>] [-rxid <rxImaIdExpected>]

describes the parameters for the cnfimagrp command.
cnfimagrp Command Parameters
Enter the group number for the IMA group you are configuring. To display
the available IMA groups, enter the dspimagrps command.
The protocol version of the IMA group.
IMA version 1.0 = 1
•
IMA version 1.1 = 2
•
The minimum number of links that will allow the IMA group to be
operational (Range: 1-16).
The IMA ID number transmitted in the IMA ID field (Range: 0-255). The
transmit IMA ID should be different at each end of the IMA link. When the
transmit ID is different at each end, the switch accurately detects link
loopbacks. If the same transmit ID is configured at both ends of an IMA link,
the switch will incorrectly determine that the link is in loopback state.
This field cannot be changed while the IMA group is up.
Note
The length of transmitted IMA frame in cells. This frame length is described
as M consecutive cells for each Tx frame.
The txFrameLen value is configurable ONLY for IMA version 1.1. For IMA
version 1.0, the txImaFrameLength value is always 128. For IMA version
1.1, the txImaFrameLength value can be 32, 64, 128, or 256 bytes.
The maximum differential delay in milliseconds. Enter a number in the range
for the appropriate link type:
• T1 range = 1 through 275 msec
E1 range = 1 through 220 msec
•
Defaults: T1 = 275, E1 = 220
0-400000 milliseconds
0 and 100000 milliseconds
Version fallback enable. The available options are:
• True = 1
• False = 2
