Re: usg50, vlans, switch

Good question.
What is efficient when comparing VLANs vs subnets wrt comparing a smart switch and a router. If you have two or three distinct groups of users that can be handled by subnets and router ports..... why buy a managed switch and use VLANs.

For multiples of groups I can see VLANs being advantageous. Also if there is a lot of traffic between units within a VLAN (more internal than internet traffic) and this can be separated from the Router it is more efficient use of router CPU?

What is done with lets say a common device that two VLAN groups need access too (aka a shared printer)? In a subnet scenario, would simply create firewall rules allowing one way access to print...... either hosting the printer in either subnet (or put these common devices in their own subnet and use firewall rules). What is the VLAN equivalent?

You would just let the port the Printer is connected to, be a member of both VLANs

Well there ya go........ The advantage of VLANs is that you can overlap devices KEWL.
