Parameter
number: Serial interface number.
Description
Using the display interface command, you can view the LAPB or X.25 interface
information. After configuring PVC of X.25, users can use the command to obtain
the status information on one interface.
Example
Encapsulate Serial0/0/0 with LAPB protocol and view the encapsulated interface
information using the following commands.
<3Com> system-view
[3Com] interface Serial1/0/0
[3Com-Serial0/0/0] linl-protocol lapb
