Configuring the Data Link Layer Protocol for E1, T1, and Serial Interfaces
Configuring the Logical Interface
The router prompt indicates that you have entered the appropriate interface
configuration mode context:
ProCurve(config-hdlc 1)#
From this configuration mode context, you can enter the
? help command to
display the commands available from this configuration mode context.
ProCurve(config-hdlc 1)# ?
Table 6-9 shows the main settings that you must configure for an E1, T1, or
serial interface that uses HDLC.
