Configuring IMA Port Adapter Interfaces
Configuring the T1/E1 IMA Port Adapter
Example
The following example shows how to change the clock source to free running:
Switch(config)#
interface atm 0/0/3
Switch(config-if)#
clock source free-running
Displaying the T1/E1 IMA Interface Configuration
To display the physical T1/E1 IMA interface configuration, use the following EXEC command:
Example
The following example shows a T1 IMA ATM interface 0/0/3 configuration, including the change to the
clock source configuration from the previous section:
Switch#
show controller atm 0/0/3
ATM0/0/3 is up
PAM State is UP
Firmware Version: 1.6
