Configuring IMA Group Functions
To configure IMA group functions on an ATM switch router, perform the tasks in the following sections:
Creating an IMA Group Interface, page 21-6
Adding an Interface to an Existing IMA Group, page 21- 8
Deleting an Interface from an IMA Group, page 21 -10
Deleting an IMA Group, page 21-11

Creating an IMA Group Interface

To create an IMA group interface, first link a physical interface to the IMA group. After configuring t he
physical interface as part of an IMA group, you can then create the IM A group interface. An IMA group
interface is identified by its card, subcard, and IMA group number. For example, IMA group 1
configured on the physical interface card0 and subcard 0 is identified as 0/0/ima1. IMA group numbers
range from 0 to 3.
Note You must create the IMA group at both ends of the connection.
To create an IMA group interface at both ends of the connection, perfor m the following steps, beginning
in global configuration mode:
Command Purpose
Step1 Switch(config)# interface atm card/subcard/port
Switch(config-if)#
Specifies the ATM port and enters interface
configuration mode.
Step2 Switch(config-if)# shutdown Shuts down the interface prior to configuring
the IMA group.
