VLAN config between data and voice...HELP!!!

[mstrmp3]

I am trying to connect a number of switches to separate voice from data. This is not in production yet, but it needs to be soon. here is a layout of the system now. Basically we have rewired the entire building and are trying to setup a new VOIP system and vsphere setup. There are 5 switches ranging from 4210's to 5210. I thought I knew what I was doing, but alas, some of the configuration setups between the swwitches are baffling. I basically want only two VLANs (101 for data and 102 for voice). Do I setup the voice ports as tagged? or is that just for the trunk port (and by trunk port, I'm assuming the port that connects the variuos switches together) I can add a vlan-interface to the 1910, but not the 4210's. How will the vlans know where to go if I can't setup vlan-interface IP's to the 4210's?

Vlan 101 has ip 10.10.1.0/24

Vlan 102 has ip 10.10.2.0/24

any info you can give me will be greatly appreciated!!!!!!!

Hi mstrmp3,

The 4210 definitely supports VLANs, so i'm not sure what the cause of your issue is there.

In answering your first question - yes, normally voice ports are set up with the voice VLAN tagged and the data VLAN untagged. If you don't have any other VLANs, you could set up the trunks between the switches the same way, and it should all work. (If you have other VLANs, GVRP is a better way of doing this if all your switches support it.)

Note that not every switch needs an IP address on its VoIP VLAN interface - you only need them on the router (if any) and the phones themselves. The switches only need 1 IP address for management.

Thanks for the info, however I have two questions.

1. It says that the 4210 can only have one vlan-interface IP set and that it must be on the management vlan. So how can I set the VOIP vlan interface ip?

2. I really need some idiots guide to setting trunks/vlans. do you know of a good reference for setting these up?

thanks again!

Hi mstrmp3,

1. Do you really need an IP on the VoIP VLAN on the 4210 switch? If my memory serves me correctly, the 4200 series do not support routing, so there's really not much value in having an IP on that VLAN. You should have another device (e.g. a 5400 series switch or an external router of some description) doing any necessary routing to your VoIP VLAN.

2. Try the 4200 series Advanced Traffic Management guide, which can be found at http://www.hp.com/rnd/support/manuals/4200vl.htm - VLANs are chapter 2 and GVRP is chapter 3.

Good luck.
