To verify correct operation of a channelized E1 IQ interface, use the following commands:
To view the interface names of the physical channelized E1 IQ interface and the resulting interfaces configured on the channelized IQ interface, use the show interfaces controller command:
user@RouterA> show interfaces controller
ce1-1/2/3
Controller Admin Link
ce1-1/2/3 up up
# This is the physical channelized E1 IQ interface.
ds-1/2/3:1 up up
ds-1/2/3:2 up up
# These are the resulting N xDS0 interfaces.
user@RouterA> show interfaces controller ce1-1/2/6
Controller Admin Link
ce1-1/2/6 up up
# This is the physical channelized E1 IQ interface.
e1-1/2/6 up up
# This is the resulting E1 interface.
To view information about the physical channelized interface, include the ce1-fpc / pic / port (interface name) option with the show interfaces command:
user@RouterA> show interfaces ce1-1/2/3
