VLAN opinion

Hi all.

I'm considering 3 vlan's for my environment to reduce broadcast traffic and improve network performance. As an engineering firm, the workstations are pulling cad drawings and working live across the network. There are times we experience latency.

There are about 55 workstations, 16 servers, and voip on 1 broadcast domain. My thought is to create 3 vlan's: 1 for workstations, 1 for servers, and 1 for voip. My thought is to purchase 2 - layer 3 managed switches. I'm currently running with 4 Netgear GS748T's for data and 2 Avaya 4550 PWR's for voip.

I'm not well rehearsed with vlan's but am quickly relearning.

Any thoughts?

I thought 2 managed switches for redundancy. Will trunking be needed between 2 - layer 3 switches?

Yes, without a doubt you will want trunking between them. I don't know what vendor you plan to go with, but I assume you will be using an HSRP/GLBP/VSS type of setup for the two switches?

Huh? I don't understand "HSRP/GLBP/VSS ". I don't want to break the bank.  What do you suggest as an L3 switch? The Profsafe L2 Netgear switches work great in my shop but I don't know how an L3 Netgear switch will perform.

I am not familiar with Netgear switches, but in regards to redundancy, what did you have in mind?

I'd like to have 2 - L3 switches for redundancy and failover. If one dies, the other will pick up the pace and not miss a beat. I have the rest of my network built with redundancy and would like to see the switch fabric similar.

Okay, that said, the Netgear switches should have some type of gateway redundancy feature/protocol to server you purpose. Make sure it does. Most likely a VRRP feature.

I jsut determined there are 2 Dell Powerconnect 7024 L3 switches on the network and that'll do what I need for this project. Have you had any experience or have any knowledge using these for vlan routing?

Yes I have used these in the past. They should serve your purpose.  I believe they should have vrrp.

The do have VRRP. Already checked. Thanks Soulja!
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Glad to help!
