Dear all,

I need advice please.

I plan to buy HP v2920-24G, but consider for the following:

1. can the switch stacked with different model (v2920 with v1910, v2920 as a main switch)
2. can I do Setting:

-          Socket 1 =  internet source

-          Socket 2, 3 = for guest

-          Socket 4 – 8 = Manager level

-          Socket 9 – 12 = Marketing level

-          Socket 13 - 24= staff officers include for Facilities (servers, NAS, network printers, etc) .

1. Socket 2,3 only can communicate with Socket 1, (if possible: only for port 80, 443, 587, 110, 25, 465, 995)
2. Socket 4-8 can communicate with Socket 1, 4 – 24.
3. Socket 4 – 8 only can communicate with socket 1
4. Socket 13 – 24 only can communicate each other.

I don’t know for that requirement, whether router can handle or not, or I need a firewall to do that.

3. Does the switch support multi-vlans to run simultaneous ?

4. what is the difference between v2920-24G and v1910-24G?

thanks
