Configuring HDLC Interfaces
HDLC is a protocol developed by the International Organization for Standardization (ISO) under standards
ISO 3309 and 4335. Originally created for the mainframe environment, HDLC has become popularly used
in many network environments because of its flexibility and ease of configuration. HDLC provides
synchronous data transmission regardless of the physical layer access. Because HDLC is totally unaware
of the physical layer access, it supports both half duplex and full duplex communication lines, can work in
both point-to-point and multi-point network configurations, and can be transmitted over switched or
non-switched channels. The SROS supports HDLC transmission over T1, E1, and serial interfaces.
HDLC configuration in SROS products consists of creating the HDLC interface and assigning an IP
address. There are no protocol-specific configuration parameters for HDLC.
The following commands specify the configuration parameters required for a standard HDLC interface:
ProCurve>enable
ProCurve#config terminal
ProCurve(config)#interface hdlc 1
ProCurve(config-hdlc 1)#ip address 172.22.15.2 /30
ProCurve(config-hdlc 1)#no shutdown
ProCurve(config-hdlc 1)#exit
ProCurve(config)#
