Managing the XSR

CAUTION

When you enable the Console port as a WAN port, you can no longer

directly connect to it because is in data communication mode. Your only

access to the CLI will be to Telnet/SSH to an IP address of a configured

port. Also, if

startup-config does not set up any of the ports properly

and sets up the console port as a serial port, you will no longer be able to

Terminal Commands

If you want to display identification information about the current terminal

connection, issue the

show whoami command. Refer to the XSR Getting Started

Guide for more information on commands.

Connecting via Telnet

Once the XSR is properly configured with a valid IP address, you can

remotely connect to the CLI via Telnet using the default user admin with no

password. Later, you can create users with the

username command.

NOTE

The XSR supports a maximum of 25 users.

Although up to five concurrent Telnet/SSH and one Console sessions are

supported, if more than one session is running simultaneously (including the

Console session), only one session permits configuration changes. Any other

session could only view configuration settings. This prohibition applies to all

commands that make changes to the configuration and is limited to Global

mode. For example, if a user is in Global mode and another user tries to enter

Global mode, the second user will get the following error message:

XSR#config

Configuration is currently locked by user admin. Please try later.

Also, in order to ensure that an administrator can always login to the router,

one of the five permitted Telnet or SSH sessions is always reserved for the

administrator.
