Configuring ATM IMA
Creating the IMA Groups (ATM Interfaces)
The following shows the configuration for IMA groups on ATM interfaces:
[edit chassis]fpc fpc-slot {pic pic-slot {aggregated-devices {ima {device-count count;}}}}
The PIC is automatically rebooted when a configuration that changes the IMA group count is committed.
