Answer : HP Switch L3 Configuration VLAN, trunking ?

Keep in mind that in the HP world, the term "trunk" refers to bundling ethernet links (what Cisco calls "etherchannel". What you want to do is what HP calls "tagging".

Also, you're using public IP addresses on your accounting VLAN. This could cause problems trying to connect to public addresses on the internet. I would suggest using a private address for the new (and existing accounting VLAN)

With what you're calling a trunk, you'll need a native VLAN. In this example, I'm using VLAN 1 but you could use any VLAN as native.
