What is VLAN and HOW............

[AV1611]

What is VLANing and how does it work. If I have machines on my network that need access to A and C networks but A and C don't need to see each other, could I use VLAN?

Thanks, AV

Yes. It creates Virtual LANs, hence the term V-LAN. They will reside on the same switch, but will not be able to see each other... Here's a good link,

Thanks a lot.

Is it possible to setup a VLAN that has computers connected to it that also connect to another network?

Yes, as long as you have your routes set up correctly...

Following is a path to help understand Vlan:

1. You may connect hosts to ports of switch. Basically all of them belong to one Vlan. If you connect 2 switches, you can reach hosts connected to the second switch if they are ine the same Vlan. So hosts are in the same 'broadcast domain'.

2. You may create Multiple Vlan and assign ports to those Vlan. Hosts attached to ports belonging to SAME Vlan can reach each other.

3. Between Vlans, if you route the traffic, so one host in one Vlan can reach another one hooked in another Vlan.

A lot of ISPs will offer VLAN based solutions, especially when it comes to dedicated ADSL links for businesses ( and we talking in the 200-400 buck range per connection here ).
