Configuring the IMA Interface

To configure the IMA interface, follow this procedure:
Command
Step 1
Router> enable
Password: password
Router#
Step 2
Router# configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
Router(config)#
Step 3
Router# ip routing
Router# appletalk routing
Router# ipx routing
Step 4
Router(config)# interface atm 1/0
Router(config-if)#
Step 5
Router(config-if)# ima-group 2
Step 6
Router(config-if)# no shutdown
Step 7
Router(config-if)# interface atm2/ima3
Step 8
Router(config-if)# ima clock-mode common
Step 9
Router(config-if)# ima
differential-delay-maximum 75
Step 10
Router(config-if)# ima active-links-minimum

Configuring Inverse Multiplexing for ATM Interfaces
Purpose
Enter enable mode. Enter the password.
You have entered enable mode when the prompt
changes to .
Router#
Enter global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Enter interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Assign the ATM interface to an IMA group
(numbered from 0 to 3). The interface is now
assigned to a group and ATM functionality is no
longer available for the individual link.
Enable the individual link by canceling the
shutdown state.
The no shutdown command at this point
Note
activates the individual ATM link. If this
command is omitted, the ATM link is
added to the group but is "inhibited" at the
IMA protocol level. This would prevent it
from carrying network traffic.
Repeat Step 4 through Step 6 if your router has
more than one interface that you need to
configure.
Create the IMA group interface.
The group interface is deleted with the no
Note
interface atm 2/ima 3 command.
Select the transmit clock mode for the selected
IMA group. The choices are common or
independent.
Enter the maximum differential delay in
milliseconds for the selected IMA group.
Enter the minimum number of links that need to be
operational for the selected IMA group.
