“logging synch”, and “exec-timeout”

Back>
Most Cisco Routers and some Cisco Switches support console-line commands include the "exec-timeout" and "logging synchronous".

The video teachs how to enable cursor following and set idle time-out time on Cisco layer 2 switch.
By default, when we enter a command, it will be interrupted by some log information or debug commands. By Enabling cursor following, our command entry will not be interrupted.
To enable cursor following, use command "logging synchronous" in the line console configuration mode.

If the keyboard has no action for some amount of time, the IOS should automatically exit the user mode. We use command
"exec-timeout minutes seconds" to set the idle time-out time. command "exec-timeout 0 0" disables time out.

As an example, the following configuration is tested on Packet Tracer 5.1 with 2950-24 switch.
-----------------------------------------------------------------------
Switch>enable
Switch#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#line console 0
Switch(config-line)#logging ?
synchronous Synchronized message output
Switch(config-line)#logging synchronous
Switch(config-line)#exec-timeout 0 10
Switch(config-line)#^Z
