Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
You can change the mode of a controller only when there are no subinterfaces defined for the controller. For
example, if you previously defined channelized T1 subinterfaces on a T3 interface and now you want to
change this to E1 subinterfaces or a clear channel interface, you must first clear the subinterfaces. To do this,
use the no controller t1 command for all defined T1/E1 subinterfaces. If you have defined serial parameters,
you also need to use the no interface serial command.
For channelized SPAs, you must use the mode command before you can configure any channelized controllers.
