Hi guys a very easy question:
what is better? or if exist another best-practices please tell me.
consider the fact only 1 ssid, 2000 user on same building (4 areas, not separete areas, they are very close)
1.- one network mask /21? for whole building?. effect: I think this generate too much traffic, broadcast etc.
2.- 4 network mask /24 each one. using vlan id group and assign one vlan x area?, effect: roming wil be at layer 3, and will be experience renewal ip and a lot conect/disconect problem?
thanks and regards
You will get difference answers from different folks, for sure.
I manage a large WLAN and have 3,000 client in the same subnet and its a voice vlan at that. I dont have any issues. The WLC will proxy the broadcast, so broadcast are never on the wireless medium. However, if I were to have deisgned this network, I would have done /22 and ap groups or a dynamic vlan.
I hope this helps
Just like what George said, you'll get different answers from different people.
We have couple of networks all are /20. All are fine (all are data).
I would study it carefully about how many users would possibly roam from an area to another before choosing. But if everything is OK I think I will end up using one subnet.
I will implement using one subnet, what version is your WLC and if the broadcast is enable for default or must be disabled?.
If there are no applications that needs broadcast then I prefer to keep it disabled.
This is also a good solution to make smaller subnets on same WLAN rathe than mapping the WLAN to same big subnet/VLAN.
