The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

To disconnect Telnet or SSH sessions, use the clear line Privileged EXEC Mode command.
clear line {ssh | telnet}
ssh—Disconnects SSH sessions.
telnet—Disconnects Telnet sessions.
N/A
Privileged EXEC Mode
switchxxxxxx# clear line telnetTo set the session idle time, during which the switch waits for user input before automatic logoff, use the exec-timeout Line Configuration mode command.
To revert to the default setting, use the no form of this command.
exec-timeout minutes
no exec-timeout
minutes—The number of minutes. (Range: 0 to 65535, 0 means no timeout)
The default idle time is 10 minutes.
Line Configuration mode
The following example sets the idle time for Telnet sessions to 20 minutes:
switchxxxxxx(config)# line telnet
switchxxxxxx(config-line)# exec-timeout 20To identify a specific line for configuration and enter the Line Configuration command mode, use the line Global Configuration mode command.
line {console | ssh | telnet}
console—Specifies the terminal line mode.
telnet—Specifies the switch as a virtual terminal for remote access (Telnet).
ssh—Specifies the switch as a virtual terminal for secured remote access (SSH).
Global Configuration mode
The following example configures the switch as a virtual terminal for remote access (Telnet):
switchxxxxxx(config)# line telnet
switchxxxxxx(config-line)#To set the login password intrusion threshold, use the password-thresh Line Configuration mode command.
password-thresh value
value—The number of allowed password attempts. (Range: 0 to 120, 0 indicates no threshold)
The default threshold value is 0, which indicates no threshold.
Line Configuration mode
switchxxxxxx(config)# line console
switchxxxxxx (config-line)# password-thresh 10To show the line parameters, use the show line Privileged EXEC mode command.
show line [console | telnet | ssh]
console—(Optional) Displays the console configuration.
telnet—(Optional) Displays the Telnet configuration.
ssh—(Optional) Displays the SSH configuration.
If the line is not specified, all line configuration parameters are displayed.
Privileged EXEC mode
The following example displays all line configuration parameters:
switchxxxxxx# show line
Console ==============================
Baudrate : 9600
Session Timeout : 10 (minutes)
History Count : 128
Password Retry : 3
Silent Time : 0 (seconds)
Telnet ===============================
Telnet Server : enabled
Session Timeout : 0 (minutes)
History Count : 128
Password Retry : 3
Silent Time : 0 (seconds)
SSH ==================================
SSH Server : disabled
Session Timeout : 10 (minutes)
History Count : 128
Password Retry : 3
Silent Time : 0 (seconds)To set the login fail silent time, use the silent-time Line Configuration mode command.
silent-time value
value—The number of seconds to disable the console after login failure. (Range: 0 to 65535. 0 indicates no silent-time)
No silent time
Line Configuration mode
switchxxxxxx(config)# line console
switchxxxxxx (config-line)# silent-time 10To set the console port baud rate, use the speed Line Configuration mode command.
To revert to the default setting, use the no form of this command.
speed bps
no speed
bps—The baud rate in bits per second (bps). Possible values are 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps.
The default console port baud rate is 9600 bps.
Line Configuration mode
The configured speed is applied when autobaud is disabled. This configuration applies to the current session only.
The following example sets the console baud rate to 115200 bps:
switchxxxxxx(config)# line console
switchxxxxxx(config-line)# speed 115200
