Managing the Switch
• Download software updates and upgrades. For more information, see Appendix A, “Software
Upgrade and Boot Options.”
The switch supports up to the following number of concurrent user sessions:
• One console session
— Two console sessions are available if two management modules are installed.
• Eight shell sessions
• Eight Telnet sessions
• Eight Trivial File Transfer Protocol (TFTP) sessions
• Eight SSH2 sessions
Understanding the ExtremeWare XOS Shell
When you log in to ExtremeWare XOS from a terminal, you enter the shell with a shell prompt
displayed. At the prompt, you input the commands to be executed on the switch. After the switch
processes and executes a command, the results are relayed to and displayed on your terminal.
The shell supports ANSI, VT100, and XTERM terminal emulation and adjusts to the correct terminal
type and window size. In addition, the shell supports UNIX-style page view for page-by-page
command output capability.
Up to eight active shell sessions can access the switch concurrently.
For more information about the line-editing keys that you can use with the XOS shell, see “Line-Editing
Keys” on page 30.
Configuring the Number of Active Shell Session
You can change the number of simultaneous, active shell sessions supported by the switch. By default,
eight active shell sessions can access the switch concurrently. If you configure a new limit, only new
incoming shell sessions are affected. If you decrease the limit and the current number of sessions
already exceeds the new maximum, the switch refuses only new incoming connections until the number
of shell session drops below the new limit. Already connected shell sessions are not disconnected as a
result of decreasing the limit.
To configure the amount of shell sessions, use the following command:
configure cli max-sessions
Configuration File Management
The configuration is the customized set of parameters that you have selected to run on the switch.
Table 9 describes some of the key areas of configuration file management in ExtremeWare XOS.
