The HP V1910 switches are powerful and economical switches. By default, you can only manage them through the web interface. Even if you enable SSH or Telnet, the commands available are minimal. Here is how to configure SSH or Telnet, enable it for your user account, and enable the full range of commands that are disabled by default. The model in this example is an HP V1910-48G:

Log into the web interface, and go to Network > Service. Enable SSH or Telnet and click apply (please don't enable telnet, really, just use SSH...):

Go to Authentication > Users. Enable SSH or Telnet for the user account you will be connecting with:

You can now log into the switch using your favorite SSH or Telnet client. As you see, there are only 7 command available, and none of them are going to help you configure the switch:

HP V1910 series switches are capable of performing "one-to-one" or "many-to-one" port mirroring. This means you can choose to have one or several ports mirrored to another port. In my example, I am using an HP V1910-48G switch.

• Log into the web interface of the switch. Click on Device > Port Mirroring > Create > Enter 1 for the Mirroring Group ID > Click Apply

• Click on Modify Port > Select Mirroring Group ID > Set Port Type to Monitor Port > Select a single port for the Monitoring Port > Click Apply (In my example, I chose port 2):

• Change the Port Type to Mirror Port > Choose Inbound, Outbound, or Both for Stream Orientation > Select 1 or more ports to be mirrored > Click Apply (In my example, I chose ports 1 & 3):
