7. Activate the serial interface.
ProCurve(config-ser 1/1)# no shutdown
By default, the ProCurve Secure Router immediately notifies you that the
interface is administratively up. It will take a few moments to establish
the serial connection, however. When the connection goes up, the
ProCurve Secure Router displays another message at the command line
interface (CLI), reporting that the line is up. If you want to disable this
reporting function, enter no events from the enable mode context.
8. View the status of the serial interface.
ProCurve(config-ser 1/1)# do show interface ser 1/1
The do command enables you to enter enable mode commands (such as show
commands) from any context (except the basic mode context).
You must now configure the Data Link Layer protocol for the serial interface
as explained in Chapter 6: Configuring the Data Link Layer Protocol for E1,
T1, and Serial Interfaces.
