Configuring the Data Link Layer
Protocol for E1, T1, and Serial Interfaces
This section explains how to configure the Data Link Layer protocol for an
E1, T1, or Serial interface. You should configure the physical interface to use
the same Data Link Layer protocol that your public carrier is using:
■ For PPP, see “Configure PPP as the Data Link Layer Protocol” below.
■ For Frame Relay, see “Configure Frame Relay as the Data Link Layer
Protocol” on page 14-68.
■ For HDLC, see “Configure HDLC as the Data Link Layer Protocol” on page
14-74.
If you need additional information about any of the options, see Chapter 6:
Configuring the Data Link Layer Protocol for E1, T1, and Serial Interfaces.
Configure PPP as the Data Link Layer Protocol
The following steps explain the initial configuration of PPP as the Data Link
Layer protocol. It is assumed that you have configured the Physical Layer—
the E1, T1, or serial interface—and you have selected PPP as the Data Link
Layer protocol. As a result, the PPP Configuration window is displayed.
