Chapter21 Configuring IMA Port Adapter Interfaces
Configuring IMA Group Functions
Note The IMA group numbers on each end of the interfa ce can differ. For example, you can configure the
interfaces in IMA group 1 on Switch A and in IMA group 2 on Switch B.
Example
The following example shows how to create the IMA group interface 0/0/ima1 shown in Figure21-1
starting with SwitchA, ATM interface 0/0/1:
SwitchA(config)# interface atm 0/0/1
SwitchA(config-if)# shutdown
SwitchA(config-if)# ima-group 1
SwitchA(config-if)# no shutdown
SwitchA(config-if)# exit
SwitchA(config)# interface atm 0/0/ima1
SwitchA(config-if)# no shutdown
The following example shows how to create the IMA group interface 4/1/ima1 shown in Figure 21-1 on
SwitchB, ATM interface 4/1/4:
SwitchB(config)# interface atm 4/1/4
SwitchB(config-if)# shutdown
SwitchB(config-if)# ima-group 1
SwitchB(config-if)# no shutdown
SwitchB(config-if)# exit
SwitchB(config)# interface atm 4/1/ima1
SwitchB(config-if)# no shutdown
Step3 Switch(config-if)# ima-group number Assigns the interface to an IMA group
number.
Step4 Switch(config-if)# no shutdown Reenables the interface.
Step5 Switch(config-if)# exit
Switch(config)#
Returns to global configuration mode.
Step6 Switch(config)# interface atm card/subcard/imagroup
Switch(config-if)#
Specifies the IMA group 0 to 3 and enters
interface configuration mode.
Step7 Switch(config-if)# no shutdown Creates the IMA group.
Step8 Repeat this procedure on the other end of the
connection.
