34 ExtremeWare XOS 10.1 Concepts Guide
Managing the Switch
Understanding the XOS Shell
When you login to ExtremeWare XOS from a terminal, you enter the XOS shell and the XOS shell
prompt is displayed. At the shell 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 XOS shell supports ANSI, VT100, and XTERM terminal emulation, and the shell adjusts to the
correct terminal type and window size. In addition, the XOS shell supports UNIX style pageview 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 24.
Configuring the Number of Active Shell Sessions
You can change the number of simultaneous, active XOS 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 XOS 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 will not be
disconnected as a result of decreasing the new limit.
To configure the amount of XOS shell sessions, use the following command:
configure cli max-sessions
Using the Console Interface
The CLI built into the switch is accessible by way of the 9-pin, RS-232 port labeled console, located on
the front of the modular switch management module.
NOTE
For more information on the console port pinouts, see the hardware installation guide that shipped with
your switch.
After the connection has been established, you will see the switch prompt and you can log in.
Using the 10/100 Ethernet Management Port
The MSM provides a dedicated 10/100 Ethernet management port. This port provides dedicated remote
access to the switch using TCP/IP. It supports the following management methods:
• Telnet using the CLI interface
• SNMP access using EPICenter or another SNMP manager
