Enable DHCP scope on WLC for particular WLAN (SSID)

[gilbilenilesh]

Hi Team,

my setup consist of below infra

We have fortigate firewall for gateway & internet access.

five access point & one WLC for them to Manage.(AIR-CT2504-K9)

These five access point are having three different WLAN (different SSIDs) 

20 Laptop users which access internet through wifi.

DHCP server configured on fortigate firewall. all clients are getting IP address directly from fortigate firewall.

Requirement

We want to setup dhcp server on cisco WLC (AIR-CT2504-K9) for only one SSID so that when user connect to that SSID they will get particular IP Address range & I can restrict those user internet access.

rest of the SSIDs will keep on continue to release IP from fortigate firewall.

Please let me know how can I achieve these without conflicting rest of the setup.

Yes its possible.

1. Create DHCP scope of specific network Which you are using for specific WLAN.

2. Assign DHCP server "WLC Mgmt INterface IP" under the dynamic interface of that wlan for whcih you are having a local dhcp scope on WLC.

You can do that, just make sure that your DHCP range is within the IP range of the virtual interface on the WLC.
Please note that later WLC will drop the DHCP server feature. You can also create ACLs on the WLC to restrict the internet traffic, regardless of the DHCP server.

Sorry for trouble.
I am very new to WLC setup & doing for the first time if you can provide me document or link that will be useful.

There are many docs available online about how to configure internal DHCP on WLC:
