Netgear GS728TP VLANs and Cisco 7960 Phones

First off, let me say I am pretty new to VLANs so thank you for your patience and assistance.

I have 2 Netgear GS728TP switches that I need to configure to work with my data network as well as a new Cisco IP phone system.  The phones are Cisco 7960 series and my understanding is they can be configured for a specific VLAN.

My question is, how do I configure my switches for both VLANs?  The phones will be plugged into the data outlet in the offices and the computers plugged into the back of the phones, so each port on the switch will need to pass both VLANs.  The switches will be daisy chained together as well.

I also need my data traffic to be passed to my data Internet connection while my phone traffic is passed to the router for my T1.

Any help in configuring these switches would be very helpful

Thank you!

If you use vlan 10 for data, it doesn't matter that vlan1 is allowed as there isn't any vlan1 traffic except the switch management (careful as you can lock yourself out of management). Just set all the pvid to 10 (leave one as 1 to manage from). The pvid is what untagged traffic coming in becomes.

Don't forget to set port 23 on the second switch the same as the first, tagged both vlans.

Traffic on each vlan needs to be on different subnets. If you need to cross vlans you use a vlan aware router, but I don't thing you need this in your setup.
Here is the configuration guide:

With that said, you will need to set up some type of voice vlan/data vlan configuration on each switch ports. In Cisco world you can add a voice vlan on the same port as a data vlan. I don't know if these switches are capable of that or not.

In regard to directing traffic to your internet and voice traffic to your T1 you will need to set up some type of policy based routing. You didn't  provide any routing information regarding your network, so that is all I can tell you thus far.

The high level version is that you need to figure out tagged and untagged packets from the phone. On other VoIP phones I've done, setting a vlan means that VoIP packets are tagged with that vlan but packets from a computer on the extra port stay untagged.

Let's call normal LAN 10 and VoIP 20
So each port with a phone/computer should be pvid 10, untagged 10, tagged 20.

Somewhere needs to be a vlan aware router that can do the out to the Internet stuff.

Thanks for the replies.  I was hoping for a little more descriptive information on configuring the netgear GS728TP switches.  I understand the basics of a VLAN for the data and a separate for the voice.  I have VLAN 1 Data (default VLAN) and VLAN2 Voice.  I have ports 1-22 on the switches untagged for 1 and tagged for 2.  I have port 23 on the first switch tagged for 1 and 2 as it connects to port 23 on the second switch.  Configured for untagged 1 and tagged 2.

On switch 1, I have port 24 untagged for VLAN 1 and not a member of any other VLAN.  This is connected to my data firewall.  I also have port 24 on switch 2 untagged for VLAN 2 as this is connected to my voice T1 router.  I am unable to remove this from VLAN 1 as i get a message that VLAN 1 is not editable.

I tried changing the Data to VLAN 10, but I am unable to remove ports from VLAN 1 as I get the message that it is uneditable.

I am stuck in some netgear policy that I can't figure out.

Thanks.  Ok, so if I set the PVID to 10 on all ports except 1 for management, then the computer traffic will be tagged with 10 since that is the PVID?

On another note, here is what I have done.

Sorry for all the posts, but I am trying my best to get this tonight so I can go home, which is 5 hours away.

I decided to make things a bit easier and start with getting things working on one switch.  I have ports 1-22 untagged for VLAN 1 (Data) and tagged for VLAN 2 (Voice) all with PVID of 1.  I have port 23 only a member of VLAN 1 and untagged with PVID of 1.  I have port 24 only a member of VLAN2 and untagged.  I was able to remove it from VLAN 1 by setting the PVID for port 24 to 2.

I set the VLAN on the Cisco phone to 2 and now the phone no longer looks for my data firewall as the DHCP server, but it does not find the voice T1 router, which I know is a DHCP as I have connected directly to it successfully in the past.  For some reason, my IP phone is still not seeing the router on port 24.

Sounds right to me.

If you set another port as pvid 2 and plug a laptop into it do you get dhcp from the t1 router? If not, give it a static and ping the t1 router.

Ok, I got it fixed.  I had the config right on my last post.  I am not sure of the reason I was not getting an IP address from the T1 router, but I rebooted it and immediately got an IP on the phone.  It seems as though the router was not responding for some reason.

Nice to know I was doing it right, with your help, but frustrating to have beat my head against a wall.  hey, learning experience, huh?

Thanks for your help.
