Setting Timeout for EXEC Privilege Mode
EXEC timeout is a basic security feature that returns Dell EMC Networking OS to EXEC mode after a period of inactivity on the
terminal lines.
To set timeout, use the following commands.
● Set the number of minutes and seconds. The default is 10 minutes on the console and 30 minutes on VTY. Disable EXEC
time out by setting the timeout period to 0.
LINE mode
exec-timeout minutes [seconds]
● Return to the default timeout values.
LINE mode
no exec-timeout
The following example shows how to set the timeout period and how to view the configuration using the show config
command from LINE mode.
DellEMC(conf)#line con 0
DellEMC(config-line-console)#exec-timeout 0
DellEMC(config-line-console)#show config
line console 0
exec-timeout 0 0
DellEMC(config-line-console)#
