Overview

This chapter briefly describes the functionality of the XSR. Refer to the following chapters in this manual for details on how to configure this functionality and the XSR CLI Reference Guide for a description of associated CLI commands and examples.

The following functionality is supported on the XSR:

•System Management - The XSR’s resources can be managed via four methods: the Command Line Interface (CLI) for full configuration, performance and fault management; the Simple Network Management Protocol including SNMP v1/v2c/v3 agent, for remote monitoring; the NetSight Atlas Router Services Manager application for firewall and ACL configuration; and the Web to gather version information. These tools control the XSR’s many hardware and software facilities. Also supported: memory management, SSH v2 server, full configuration backup and restore, EOS Fallback for reliable image upgrades, Simple Network Time Protocol (SNTP v3) client and server (unicast mode) external source synchronization, login banner, and a host of proprietary and standard MIBs including Download, Syslog, Configuration Management, Configuration Change, Timed Reset, Chassis, Persistence, Host Resource, Enterprise Firewall and VPN, and Protocol MIBs (OSPF, RIP, Frame Relay, and PPP), SNMP Informs and Service Level Agreement (SLA) agents. The XSR’s SNMP MIBs support readable checksums on XSR configurations and the Enterasys Configuration Management MIB will TFTP a file on-the-fly to the XSR Flash, load the file to running config and save it to startup-config. The XSR also supports placing a hostname in the Syslog message header and configuring multiple Syslog servers.

•Remote Auto Install (RAI) - automatically retrieves a centrally managed configuration specifically created for a remote XSR by one of three methods: over a Frame Relay network using the lowest numbered serial port, a PPP connection using the lowest numbered serial port, or over an ADSL connection.

•Ethernet Interfaces - The XSR 1800 Series’ two 10/100 Base-T FastEthernet interfaces and XSR 3000 Series’ three 10/100/1000 BaseT GigabitEthernet interfaces handle the router’s LAN traffic stream, with support for alarms and events, diagnostics, packet filtering and statistics gathering, and Ethernet backup.

•T1/E1 & T3/E3 Interfaces - The XSR’s T1/E1 and T3/E3 subsystem on NIM-based I/O cards handle the router’s WAN traffic with support for alarm detection and signaling, diagnostics, line encoding, the Drop & Insert NIM, and a host of other functionality.

•Serial Interface - The XSR’s NIM serial interface typically supports PPP providing both asynchronous and synchronous protocol support. The XSR’s Console port can also be used as a Serial connection to the router for remote or backup dialin.

•PPP (WAN) -The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP defines procedures for the assignment and management of network addresses, asynchronous and synchronous encapsulation, link configuration, link quality testing, network protocol multiplexing, error detection, and option negotiation for such capabilities as network-layer address negotiation
