Making a PC a member of more than one VLAN
I'm sorry to post this here as it should go in the enterprise forums. I am considering purchase of a GP724 switch and cannot get access to these forums until I purchase. Hence my general question on v...
- Think of it this way - you have two separate networks - completely separate - separate switches, separate servers, separate clients - two physically separate LANs.
Now put them on a single switch, separated logically into two virtual LANs - or VLANs.
If you need to communicate between the physically separate LANs, you need to link them with a router, with each LAN being connected to a different interface.
If you need to communicate between your two virtual LANs you need to link them with a router, either one with physically separate interfaces, or one that supports VLANs - this router can also be a "route switch", or layer 3 switch.
It's quite unusual to have a client system connected to two VLANs simultaneously, the norm would be to have it on one VLAN and access the other VLAN through the router linking the two - it is however possible to have a server connected that way, especially if you're running virtualization on that server.
You could configure a switch port as a trunk port or tagged port so that it passes the VLAN tags, but if the PC does not know how/what to do with the VLAN tags, it won't work.
Thank you fordem.
"If you need to communicate between your two virtual LANs you need to link them with a router, either one with physically separate interfaces, or one that supports VLANs - this router can also be a "route switch", or layer 3 switch."
I have a Draytek 2820v that supports VLANS. Im not sure if it will link two if them though so will investigate this further. It has four ports that can each become a seperate VLAN connection.
I have a NAS and a network printer that I want all devices to see. I could leave these connected to the router and then run off two trunk connections to a Switch with two VLANS.
One secure and one for my wireless that I am trying to seperate for PCI compliance reasons.
Im I right in thinking that each of the two VLANs will see the printer and NAS on the router?
