Parameter
dte: Set DTE as operating mode of the interface.
dce: Set DCE as operating mode of the interface.
ip: Set the IP as the network-layer protocol supported by LAPB.
Description
Using the link-protocol lapb command, you can configure the link layer protocol of the
interface to LAPB.
By default, LAPB interface works in DTE mode. IP is the default protocol.
Though a layer-2 protocol of X.25, LAPB can act as an independent link-layer protocol
for simple data transmission on serial interface. Generally, LAPB can be used when two
routers are connected directly with a dedicated line. Now one end works in DTE mode,
and the other in DCE mode.
For related commands, see display interfaces.
Example
# Set the operating mode as DCE and specifies LAPB on Serial0.
