Note
If a line you want to add to the IMA group is up, enter the dnln <x.line> command to bring that
line down. A line must be down before you add it to an IMA group.
Step 3
Enter the addimagrp command to create the IMA group, as shown in the following example:
MGXswitch.7.PXM.a >
addimagrp
<
group> <version> <minLinks> <txImaId> <txFrameLen>
<txclkMode> <diffDelayMax>
describes the parameters for the addimagrp command.
Table 3-4
addimagrp Command Parameters
group
Enter an IMA group number using the format bay.line. On a
PXM1E, the bay number is always 2 and the range for lines is
1-16.
version
IMA version. Enter one of the following values:
•
Version 1.0 = 1
•
Version 1.1 = 2
minLinks
Minimum number of links required for group operation. For
example, if you create an IMA group of 4 lines and specify a
minimum number of 3 lines, then three of the four specified
lines must be operational before the IMA group can be used.
The range for this value is from 1 to n, where n represents the
number of lines that are dedicated to the group.
txImaId
Transmit IMA ID, which is 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.
