I have 400 Pcs (Servers, desktops and Laptops), one core switch, multiple access switches and a few wireless access points. Can i have some recommendations or configuration examples for configuring vlans for my network and how many vlans should i have?
Thanks!
How long is a piece of string?
As a general rule, I apply a distinct VLAN for each purpose - one for servers (no DHCP), one for workstationed 9DHCP enabled), one for printers etc. But this doesn't always work - for example, my current $POE has multiple building levels and more workstations than I am comfortable having in a single broadcast domain - so I have a couple of workstation VLAN's per floor, absed on georgaphic location (which half of the floor) as well as function for workstations, which limits the size of the broadcast domain to something more reasonable.
You don't mention switch types or machine, so this is very generic, however I'd do the following.
1) Configure your core switch with as many VLAN's as you want/need based on your location, and configure all SVI's on this core switch to allow for intra-VLAN routing.
2) Enable 802.1Q trunking between your core switches and access switches, but don't put any SVI's on these (except maybe for management of the switch itself). If your access switches are purpose-specific (I.E. they only have workstations plugged into them), then just trunk the workstation and switch management VLAN's to this switch. If you have multiple device types plugged into a given switch, then trunkt he appropriate VLAN's to that switch - try to avoid trunking VLAN's which aren't used by a particular access switch.
NB: VLAN NUMBERS must match between switches - and, unless you have VTP turned off (transparent), the names must match as well, or things will get flakey. VTP use is up to you - if you don't understand it, then don't use it - set it to mode transparent on all switches and forget about it.
Without some hard numbers, there's not much more that can be said, really.
Good luck!
