vlans design

[Joli Martinez]

I am new to to vlans.  I am the admin of a small setup with aprox 100 nodes. Including servers, printers, and workstations.  How should implement vlans.  Should i do servers on one, printers on another and workstations on another or put the fileserver on the same vlan as the workstations and then separate the printers or put them all on the same vlan.  What is the best setup for something like this?

[Reza Sharifi]

For that amount of nodes, you can simply put all the printers and workstations in one vlan and put all your servers in a different vlan.

Example

vlan 10 ip 10.10.10.0/24 wk and printers

vlan 20 ip 10.10.20.0/24 servers

I have three server. A file server, web and an email server.  should i put all the servers on one vlan or place each server on a separate vlan?

[Jon Marshall · Accepted solution]

Generally speaking you would have one server vlan for that number of servers.

As Jon also noted, one vlan for all servers.  You don't need one vlan per server.  That will cause too much unnecessary admin work

For 100 hosts, only 3 being servers, you can also just leave everything in one VLAN/subnet.

Splitting your network will generally require routing between the subnets.  L3 switches are also generally more expensive than pure L2 switches.  (NB: a small router generally doesn't support full LAN bandwidths.)

Perhaps one major reason for splitting such a small network, if you see the need to implement security between the two VLAN/subnets.
