Hello,

There is an HP 1920 switch with 24 ports, and it needs to be divided into two separate virtual switches. For example, port 1-8 is vlan 1, and port 9-24 is vlan 21. Both Vlans must use the same subnet, for example 10.0.0.1/24. Gateway 10.0.0.1 is plugged into port 1, computer 10.0.0.21 is plugged into port 21. Access of computer 10.0.0.21 to gateway 10.0.0.1 should appear only if both vlan-based virtual switches are connected via port 8 - 9.

Hi

So, you want to split a switch in 2, and have a "physical" interconnect between them ?

Strange (1920 is capable of routing) but nevermind :

the only way to do it is :

• disable spanning-tree (if you need STP, you're quite dead) or any other loop protection function.
• don't use hybrid ports for 1/0/8 and 1/0/9 : only access (untagged)
  • 1/0/8 access vlan 1
  • 1/0/9 access vlan 21

Hi frmeunier.

That's what I tried to do. I managed to do it on HP 1920S. But I can't do it on 1920. It looks like there are some configuration features in the old firmware. Any ideas on what to do?
