About This Chapter

The High-level Data Link Control (HDLC) is a bit-oriented link layer protocol. HDLC features

transparent transmission of any type of bit flow. A trunk can aggregate multiple interfaces into

an aggregation group to implement load balancing on member interfaces for received and sent

packets. At the same time, the connectivity can be of higher reliability.

3.1 HDLC and IP-Trunk Interface Overview

The High-level Data Link Control (HDLC) is a typical bit-oriented synchronization data control

protocol. It adopts the full-duplex mode and CRC check. Its transmission control function is

independent of the processing function, and thus it features control capabilities and can be

flexibly used.

3.2 Features of HDLC and IP-Trunk interfaces on the switch

The protocols in the standard HDLC suite operate on synchronous serial lines. An IP-Trunk

consists of POS links only. The link layer protocol of the interfaces joining an IP-Trunk interface

must be HDLC.

3.3 Configuring HDLC

This section describes how to configure basic HDLC functions. Detailed operations include

configuring the data link protocol of an interface as HDLC, an IP address for an interface, and

the polling interval.

3.4 Configuring an IP-Trunk Interface

This section describes how to configure an IP-Trunk interface. Detailed operations include

creating an IP-Trunk interface and adding interfaces to the IP-Trunk interface, and configuring

an IP address for the IP-Trunk interface, the lower threshold of Up links.

3.5 Maintaining HDLC and IP-Trunk Configuration

This section describes how to maintain HDLC. Detailed operations include clearing the statistics

about the HDLC interfaces.

3.6 Configuration Examples

This section provides several examples for HDLC and IP-Trunk. These configuration examples

explain the networking requirements, configuration roadmap, data preparation, configuration

procedure, and configuration files.
