Vlan security

Hi,

I just got my hands on a Nortel Baystack 350T-16 and i have never setup a VLAN before. I was wondering what kind of security can i get if i had my servers on one VLAN and a few clients on another VLAN? Can this pose a security issue or would this really be like two seperate networks? Also does each VLAN need it's own uplink or can one be used? If anyone could tell me that would be great, if not i'm sure i'll figure it out.

Thanks

You are correct on the basic of vlan. In basics it is like have seperate switches. Niether vlan can see the other unless configurations are enabled. Never used a baystack before so cannot help on configuration between vlans. Pretty much the interfaces work on a lower level of the tcpip stack.

Hope this helps.

Yes you can have multiple VLANS on a single port, but this then becomes whats known as a trunk or I believe in nortel terminology a tagged port. If two switches are connected via tagged ports you can have vlans on multiple swiches while maintaining layer 2 separation.
