Community VLAN or Isolated VLAN (determine type)

Hello,

How to determine if a VLAN should be Community or Isolated ?

I know what they are and do, but not sure how to choose for one to another.

VLAN for students...Isolated or Community ?

VLAN for Teachers...Isolated or Community ?

VLAN for administration...Isolated or Community ?

VLAN for Servers (mail, backup, etc...)

etc...

I am new as a network IT and need some help for a school project.

TOPO:

School = Private VLAN; segmentation = secondary VLANs (Isolated or Community...what to choose ?)....

 

TY,

Hi Bhastiann It entirely

Hi Bhastiann

 

It entirely depends on your requirements :)

 

Admins are generally considered to have access everywhere so maybe best as promiscuous.

If the other groups need to connect to each other then they need to be in a community.

Infrastructure generally do, and you could say they are trusted so why not place them in a single community.

If you don't want students to connect directly, place them in an isolated. I'd trust teachers even less :) The method to share files should be by file server.

Don't forget, subnetting and access control. I wouldn't recommend placing all devices in a single subnet. depends on how many you have, but certainly a subnet for end users (teachers, students) and infrastructure would be a good idea.
