Nub, cisco, aerohive networking question.

I am relativly ignorant but looking to learn. I am hoping for some guidance.
We have a cisco small business router RV042 and several Aerohive switches and AP's. We have identified the need for 7 vlans: employees, guests, QA, support, voice, and a few more.
My understanding is that the RV042 only does port based vlans and since it only has 4 ports I cannot integrate it very well with our aerohive stuff. We are using the Cisco router for its load balancing abilities (and someone more important than me does not want to change it).

My question is, should I configure one of the aerohive switches as a router with DHCP services for each VLAN subnet and use the cisco router to feed that aerohive switch router? Basically:
(cisco router)----(aerohive switch/router) ----s APs).
Or should I do something else?

From my perspective
A switch should switch
A router should route

Not saying you shouldn't, just saying that a switch as a DHCP server and a router would work for small enviornments, but it is not scalable. You will also need to pay attention to memory usage of these devices.

So for me
I would do intervlan routing
but would build dhcp and dns servers separately
Depending on the environment and skill level and budget
Ubuntu servers or Freebsd boxes work well and can provide some redundancy

Hi Abe,

You can turn the SR series switches into a Router, but I would recommend using an external box for DHCP.

Yeah, we are running into issues with DHCP using the current switch in router mode. I think we are going to set this up now. Thank you.
