Configuring Serial Interfaces for E1- and T1-Carrier Lines
Viewing Information about the Serial Interface
Viewing Information about the Serial
Interface
You can view information about the E1- and T1-carrier line associated with
the serial interface, and you can view the configuration settings that have been
entered for the serial interface.
show interfaces serial Command
To view information about the serial interface and the carrier line associated
with it, enter the following command from the enable mode context:
Syntax: show interfaces serial <slot>/<port>
You can also use the do command to enter this command from any context
(except the basic mode context). For example, from the global configuration
mode context, enter:
ProCurve(config)# do show interfaces serial 2/1
This command displays information about the serial interface in slot two. (See
Figure 5-7.)

The first line reports the status of the interface. The status will be one of the
following:
■ up
■ administratively down
■ down
