Cisco – 802.1Q VLAN Tagging over WiFi (Meraki)

ciscomerakivlanwireless

I've recently inherited an all wireless network that has every single client in the native VLAN, at multiple sites. The site in question currently has around 550 clients on a /22, which I feel is causing issues during peak times with an alarming number of broadcasts.

So my question is:
Will splitting this up into separate VLANs while allowing every VLAN to be passed along the trunk ports (All AP switchports are setup as Trunk ports), and placing certain clients on their preferred VLAN, improve performance?

With Cisco Meraki APs you can create group policies that will tag an individual client to a particular VLAN

I would segment the VLANs based on the local structure. e.g.:

  • Floor Level1 => VLAN101
  • Floor Level2 => VLAN102

This is a quite static approach in segmenting your network and much more simple to implement than using group policys. In my opinion troubleshooting is also simplified in this approach.

Group policys are great for an organisation-based segmentation of your network, but in my opinon unnecessary if only the size of your broadcast-domain is your aim.
