Chapter 3 Configuring with the Command-Line Interface Configuring Inverse Multiplexing for ATM Interfaces 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 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. 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. 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 2 Step 11 Router(config-if)# ima test link 4 Step 12 Router(config-if)# ip address 192.168.74.3 255.255.255.0 Repeat Step 4 through Step 6 if your router has more than one interface that you need to configure. Create the IMA group interface. Note The group interface is deleted with the no 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. Select the test port for the selected IMA group. The link number is one of the physcial ports on the network module. Assign an IP address and subnet mask to the interface.
