Tutorial HP Switch - Configure Trunk using the command line
First, you need to access the console of your HP Switch.
In our example, we are going to use a Opensource software named Putty and a computer running Windows.
The Putty software is available on the putty.org website.
After finishing the download, run the software and wait for the following screen.
To access the console of an HP Switch model 1910 or 1920, you will need to select the Serial Connection category and use the following options:
• Connection type: Serial
• Serial line: COM1
• Speed: 38400
If COM1 does not work you will need to try to use COM2, COM3, COM4 or the next.
On the prompt screen, enter the administrative login information.
Factory default access information:
• Username: admin
• Password: (No password)
After a successful login, the console command-line will be displayed.
HP Switch models like 1910 and 1920 usually hide the complete list of commands available.
Use the following command to enable the Secret access mode.
The secret mode offers access to all the commands available.
You will be asked for the Factory password to enable the secret command line access.
• HP Switch 1910: 512900

Use the system-view command to enter the configuration mode.

Vlan 1 is the default native VLAN of HP Switches.
Don't forget to save your HP switch trunk configuration.

You have successfully configured a Switch port as a trunk.
