Utilizing the Command Line Interface

Managing the Session

A first-time CLI session is set up with default attributes; e.g., the session is set to time out after 1800 seconds of idle time. You can reconfigure session values such as create users, passwords, and login banners, and set Telnet and Web access. Refer to the XSR CLI Reference Guide for details about these commands.

Remote Auto Install

The Remote Auto Install (RAI) feature automatically retrieves a centrally managed configuration specifically created for the node’s operation in your network. Basically, RAI sends a configuration file from a TFTP server for configuring the remote XSR. This file is then placed in the Flash: directory as the startup-configand run via the normal startup process. RAI can be performed by one of three methods: over a Frame Relay network using the lowest numbered serial port, a

PPPconnection using the lowest numbered serial port, a PPPoE connection using the ADSL network, or over an LAN connection using the lowest number Ethernet port.

RAI simplifies management and deployment of the XSR. Because device configurations are stored centrally on the TFTP server, re-configuring the XSR requires only a remote reboot. Installing the device at a new location involves deploying a new startup-configfile with a corresponding name (based on the serial number or hostname) and rebooting the XSR.

Described in further detail, these choices are:

•RAI over Frame Relay is performed over a Frame Relay network. The RAI central site includes a Bootp server on a DLCI to deliver the local IP address for the branch (remote) site in order to communicate with the configuration management server.

•RAI over PPP can be performed over either leased or dial-up lines. Leased line RAI operates similar to Frame Relay RAI in that it is perfomed over a serial link via a leased Telco line. Dial- in RAI occurs where a designated port is configured and waiting for the central site to dial in. Dial in can utilize a modem attached to the XSR’s serial or switched BRI/ PRI interfaces.

•RAI over ADSL can be performed over the ADSL network. XSR uses the auto discovery mechanism to identify an existing PVC on the ADSL line and tries to retrieve the startup configuration using PPPoE and TFTP over that PVC.

•RAI over Ethernet utilizes a DHCP client/server methodology to quickly retrieve a particular file from a TFTP server that will be used to configure the remote XSR.

Refer to the “Software Configuration” chapter of the XSR Getting Started Guide for a RAI configuration examples and phased output from the program.

RAI Features and Requirements

At the branch site, the XSR supports the following Frame Relay IETF features:

•Operates on Serial NIM interfaces only - lowest slot/card/port only.

•Standard physical Serial media-types.

•DTE LMI type ANSI, ILMI, Q933 supported.

•Up to 30 DLCIs supported on Frame Relay (FR) connection.

•Bootp client.

•Reverse DNS client.

•TFTP client.
