Layer 3 Switching to Subnet Network

By mmiller ·
I am trying to subnet our network into smaller networks to reduce traffic. I have two Layer 3 switches (Netgear) and several Layer 2 Switches. I can get the Subnets to get Internet Access, but cannot get them to communicate between them. The Plan is have the following Networks. 1-Office, 2-Marketing, 3-VOIP, 4-Plants, 5-Security Cameras, 6-Security - Card Access. I have all the Vlans set up on the switches. Any help would be appreciated.

Vlan Communications accross Vlans

by PC Medic In reply to Layer 3 Switching to Subn ...

I am a bit rusty with vlans, but have done some in past jobs. Depending on which Vlans you want to communicate with each other you need to set up an access list, I believe is the terminology, that would allow the different ones to communicate. Also, depending on the network physical layout, you may program specific ports for the vlans to access muliple vlans. When I worked with Cisco 2900, and 3800 series switches, we were able to segment the network in a similar way for the different locations we supported using the VLAN PORT ACCESS from the command mode. I would think that the netgear cbos would be similar to the cisco one as they are the same company now. Hope this gives you some ideas. Mean while I will dust off some off my old cisco manuals and see if I can come up with something not so vague...
