exclude | include } regular-expression ]
Available in any view.
Display the configuration and state
of a serial interface formed on a
CE3 interface.

view.
Shut down an E1 line. e1 line-number shutdown
Available in CE3 interface
view.
Bring up an E1 line. undo e1 line-number shutdown
Available in CE3 interface
view.
Shutting down/bringing up a CE3 interface also shuts down/brings up the E1 lines demultiplexed from
the CE3 interface, the serial interfaces formed by the E1 lines, and the serial interfaces created on E1
lines by means of timeslot bundling.
Shutting down/bringing up an E1 line also shuts down/brings up the serial interface formed by it and
the serial interface created on it by means of timeslot bundling.
To shut down/bring up only a serial interface formed by E3 or E1 lines, or by timeslot bundling on an E1
line, run the shutdown/undo shutdown command in the view of the corresponding serial interface.
