Chapter 8 - Internetworking and Management Overview
APPLICATION
The Campus-REX2 must be installed into a Campus-RS or Campus-HRS desktop unit or with a Campus-RS or Campus-HRS line unit. It cannot be installed in an older Campus desktop unit or with an older Campus line unit.
The Campus system, implementing Campus-REX2 interface cards, provides a connection between geographically distributed Ethernet Local Area Networks (LANs) in a campus environment. The Campus-REX2 performs transparent 802.3 MAC bridging or IP routing. You can use existing telephone-grade copper wiring as the HDSL transmission medium.
When installed in a Campus-RS desktop unit or Campus-Star chassis, the Campus-REX2 functions as a remote bridge or IP router. You can use the Campus-REX2 to extend subnetworks to remote sites within a campus. Or, for sites separated by greater distances, you can use the Campus-REX2 to connect them through a public T1/E1 Wide Area Network (WAN). See “Point-to-Point LAN Extension” and “LAN Connections Over a WAN” on page 123 for more information.
Campus-REX2 software provides complete main bridging tasks of learning, forwarding, filtering, and hashing/buffer management, 802.1d Spanning Tree protocol, 802.3 drivers, packet sequencing, segmentation and reassembly, and other local tasks.
The Campus-REX2 10/100Base-T interface operates in either half- or full-duplex mode which is determined by autosensing its network connection. Both the LCD menu and console menu displays the mode.
The Campus-REX2 performs full-bandwidth filtering on the 10/100Base-T port and forwarding at the selected transmission rate.
