Managing The Session; Remote Auto Install; Rai Features And Requirements - Enterasys Security Router X-PeditionTM User Manual

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
directory as the
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, 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
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

• DTE LMI type ANSI, ILMI, Q933 supported.
• Up to 30 DLCIs supported on Frame Relay (FR) connection.
• Bootp client.
• Reverse DNS client.
• TFTP client.
