WLC question
HI
I have 4 different subnets and they all belong to vlan 99
192.168.0.1/24
192.168.1.1/24
192.168.2.1/24
192.168.3.1/24
My question is how I must setup the dynamic interface on wlc for vlan 99 as I can only have one vlan assign to an interface.
Basically I want to use different subnets with same vlan on wlc as each building has a different subnet.

Ahh okay I will use flex connect so basically I will remove the ip from my dynamic interface as I will have multiple subnets and I cannot create different dynamic interface on my wlc with same vlan .
Is this correct.

No leave the IP on the interface - it won't be used but the WLC will complain if you delete it.
You will need to configure the ports on the switches where the APs connect as trunks though, instead of access ports.

ok so they dynamic interface ip can be any ip in the range of my 4 subnets

thanks craigbeck
last question when i use flex connect the dynamic interface ip address is basically not used

Yes when you use FlexConnect the traffic for whichever WLAN you use in FlexConnect mode doesn't come back to the WLC, so the interface at the WLC isn't required. You can mix it though, so you can set a WLAN to use FlexConnect, but if the AP you publish the WLAN on isn't in FlexConnect mode it will use the dynamic interface at the WLC on that AP.

perfect thanks
If you want to separate the client traffic at each site using the same VLAN ID you need to use FlexConnect to enable the client traffic to be terminated at the switch at the site where the user actually is.
You'd configure the WLAN for FlexConnect in the Advanced tab, then change the mode on the AP to FlexConnect. That will allow you to detach the IP addressing from the VLAN on the WLC.
However this can affect your network design if you've already accounted for the fact that wireless user traffic doesn't terminate at the local site (meaning potentially less firewalls or firewall rules).
