VLAN plan/implementation help?

Hello everyone,

This is my first experts-exchange post, but I'm hoping all of your expertise can help me.

I'm fairly green when it comes to VLAN implementation, especially on HP Procurve hardware (there isn't nearly the documentation out there compared to Cisco).

I'll try and give you the goal of the project, as well as provide as much information as possible.


This scenario is an old K-12 school, so the cabling to the individual rooms isn't ideal. There's usually just one uplink to each classroom. We're looking to separate the traffic of all of our computer labs from the rest of our network. However, we still need those computers to talk to our server stack (AD, DNS, Fileserver, etc) for various reasons. I know this should be possible using inter-vlan routing, but after a few unsuccessful days of trying I'm looking for some guidance.

So, I'm pretty sure that all of the ports are connected to the computer labs need to be "untagged" in VLAN10, and all of the interconnecting links need to be "tagged" in VLAN 10. But perhaps I'm understanding it wrong. I'm sure this will come quite simple to you folks, so if you could just give me a configuration from one switch to another, I can probably figure it out for the rest of the labs.

Other things to consider: The Procurve 2910al is a Layer 3 switch. The 10.0.0.0/19 network is addressed via DHCP. The 10.0.32.0/19 network (for VLAN 10), we're prepared to statically assign (since they're desktops anyways).

If you need more information, I will be more than happy to provide. I may not be able to test this again until Wednesday, but will make sure to give credit where it's due.

Thank you very much for your help.
