Checking Your Work

To verify correct operation of a channelized E1 IQ interface, use the following commands:

show interfaces
show interfaces controller
show interfaces interval (for E1 and channelized E1 channels)

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 NxDS0 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:
