Configuring IMA is a 3-step process, which is described in the following sections:
1. Creating an IMA Group
2. Adding an IMA Link to an IMA Group
3. Adding an IMA Port to an IMA Group
Note Both ends of an IMA connection must support IMA, and the IMA configuration must match on both
ends.
Creating an IMA Group
To create an IMA group and add it to an ATM port, use the following procedure:
Step 1 Establish a configuration session with the active AXSM-32-T1E1-E.
Step 2 Enter the dsplns command to display all configured lines on the current card.
Note If a line you want to add to the IMA group is up, enter the dnln <x.line> command 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 a new IMA group:
addimagrp <group> <version> <minLinks> <txImaId> <txFrameLen> <txclkMode> <diffDelayMax>
Table 3-4 describes the parameters for the addimagrp command.
