Disable ports from CLI interface on 24 port 1920G Switch

Hi everyone from Italy !

I'm trying to disable the port state of some of my 24 ports 1920G switch, but I don't find the commands that can do it from CLI interface. Obviously I see how to do it from web interface, but I have to do this function from CLI interface because I'd like to enable, for example, port 1 from a batch file that will be executed prior a backup job on a NAS connected to that port and then, when backup is ended correctly, execute another batch file to disable the same port 1, to automate the connection/disconnection of the NAS and prevent in this way any issue and danger from virus like cryptolocker & C.

I see there is a "_cmdline-mode on" mode for enabling many others command from CLI interface, but I still haven't found what I'm looking for (thank you U2)

Can anyone help me ?

Thank you in advance for the attention !

Hi Robymos,

Here's how to enable/disable ports using the 1920 CLI...

The current configuration will be written to the device. Are you sure? [Y/N]:y
Please input the file name(*.cfg)[flash:/startup.cfg]
(To leave the existing filename unchanged, press the enter key):
flash:/startup.cfg exists, overwrite? [Y/N]:y
Validating file. Please wait............
The configuration file flash:/startup.cfg will be automatically backed up as flash:/_startup_bak.cfg for a future version downgrading.
Active main board:...
Backup done.
All backups completed.....
The current configuration is saved to the active main board successfully.
Configuration is saved to device successfully.


To 'enable' a port, the command is 'undo shutdown' ('undo' is the equivalent of prefixing a command with 'no' on cisco)


Hope that helps,
