Hi
We have 2 Named Vlan Pools each with 3 vlans assigned to them. We have preserve client vlan enabled on the VAPs.
Upon implimentation we noticed that clients weren't being balanced across the vlans that well. Clients would join the vlans randomly and in no presice order or ballanced (this was when we had aproximately 60 clients) - when we reached our peak of around 900+ clients, 2 of the DHCP scopes (2 vlans) in the one named pool was full - in the other pool the one DHCP scope filled up.
The scopes that werent full in both the pools were utilised only 50%.
Looking at a clients vlan history - it shows that the client has had 3 different vlans (if I am reading it correctly) -- does this mean the presrve isn't working or how do I change the frequency of the VLAN resets seen below.
