This chapter introduces the key features of the XSR-3020 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-3020 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 up to 1000 simultaneous VPN tunnels at 100
Mbps using 3DES. 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
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.
