Overview

This chapter introduces the key features of the XSR-3150 and briefly describes hardware installation.

System Description

The XSR is a networking device designed for enterprise regional offices that provides IP routing over GigabitEthernet LAN and T1/E1, Serial (RS232, X.21, V.35, RS422/530, RS449), Dial Services via POTS, ISDN (BRI/PRI) or Frame Relay WAN connections. Virtual Private Network (VPN) support is also provided in Site-to-Site or Remote Access applications.

The router can be managed using the Command Line Interface (CLI) and monitored using SNMP v1, v2c/v3 (with standard MIB-II and proprietary MIB support). The XSR also provides Web access to display device data.

The XSR-3150 can be configured to support the following applications:

•Regional Router - The XSR serves as a router with multiple WAN link support. It is also capable of providing the same VPN support as the full-featured VPN Gateway for customers who wish to integrate both applications in the same system.

•Full-Featured VPN Gateway - The XSR supports more than 5000 simultaneous VPN tunnels at 300 Mbps using 3DE. The VPN Gateway supports the same functionality as the Aurorean Network Gateway series but without local hard disk support.

•Firewall platform - The XSR provides a stateful inspection firewall. Processing is performed on the dual MIPS core at 300 Mbps.

A typical deployment of the XSR might be in two branch offices connected to a regional office, as illustrated in Figure 1-1. In this example, one XSR with its associated sub-network has an E1/T1 or high-speed serial WAN connection as its primary link to the Public Service Telephone Network (PSTN) with an asynchronous modem connection in a backup capacity.
