Chapter 3.  Managing the Switch  
NETGEAR 8800 User Manual 
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 XCM8800 Shell
When you log in to XCM8800 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. 
By default, up to eight active shell sessions can access the switch concurrently; however, you 
can change the number of simultaneous, active shell sessions supported by the switch. You 
can configure up to 16 active shell sessions. Configurable shell sessions include both Telnet 
and SSH connections (not console CLI connections). If only eight active shell sessions can 
access the switch, a combination of eight Telnet and SSH connections can access the switch 
even though Telnet and SSH each support eight connections. For example, if you have six 
Telnet sessions and two SSH sessions, no one else can access the switch until a connection 
is terminated or you access the switch via the console. 
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 number of shell sessions accepted by the switch, 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
On a modular switch, the console port is located on the front of the management module 
(MSM/MM). On a stand-alone switch, the console port is located on the front panel.
