Chapter 3 Configuring with the Command-Line Interface
Configuring Inverse Multiplexing for ATM Interfaces
Configuring the IMA Interface
To configure the IMA interface, follow this procedure:
Command Purpose
Step 1
Router> enable
Password: password
Router#
Enter enable mode. Enter the password.
You have entered enable mode when the prompt
changes to
Router#.
Step 2
Router# configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
Router(config)#
Enter global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Step 3
Router# ip routing
Router# appletalk routing
Router# ipx routing
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Step 4
Router(config)# interface atm 1/0
Router(config-if)#
Enter interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Step 5
Router(config-if)# ima-group 2
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.
Step 6
Router(config-if)# no shutdown
Enable the individual link by canceling the
shutdown state.
Note The no shutdown command at this point
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.
Step 7
Router(config-if)# interface atm2/ima3
Create the IMA group interface.
Note The group interface is deleted with the no
interface atm 2/ima 3 command.
Step 8
Router(config-if)# ima clock-mode common
Select the transmit clock mode for the selected
IMA group. The choices are common or
independent.
Step 9
Router(config-if)# ima
differential-delay-maximum 75
Enter the maximum differential delay in
milliseconds for the selected IMA group.
Step 10
Router(config-if)# ima active-links-minimum
2
Enter the minimum number of links that need to be
operational for the selected IMA group.
