Need help to Connect 10 FortiAps to cisco Switch which is Connected to my Firewall Fortinet 100F

[Tazio4436]

Hi,

I am trying on my own to figure out how to replace my existing Aps with FortiAps 431F. I am planning to replace all the Switches which are Cisco and some are HP in the short run but for now am just replacing the APs.

It is a live network and I am very cautious as each time I am trying something I am doing a backup.

I can see the SSID on my phone and laptop but I cannot connect.When I try to connect it shows connecting and then Couldn't get an IP address.

Can any one guide me where to start checking and what to check please.

Thanks

Tazio

So, you meant the DHCP server is located at the root Cisco switch, not at the FGT? (You should have told us at the beginning)
Then, IP assignement by the DHCP server wouldn't work if the SSID is tunnel mode. You need to consider changing SSID to bridge mode, or putting SSID interface and the VLAN to reach the DHCP server together in a software switch (I haven't tried it before so not sure if it's feasible though).
