Am connecting my fortiap directly to fortigate interface (vlan switch) with name of Data and vlan 5, the interface have dhcp sever enabled, and I have created ssid with vlan 5 so it will be on data vlan and assign ip from dhcp server,

I have the fortiap authorized and had an ip from vlan 5 dhcp, but when a client connected to ssid it will not obtain an ip and instead had apipa address, any ideas on how to get it fixed?

Hi @qsosan

 

Good day! 

 

According to the issue description, I understand you are having trouble obtaining an IP address from your DHCP server via VLAN5. 

 

When a DHCP server is unavailable, a machine system is typically assigned an APIPA address. 

 

Please see the documentation below to perform some dhcp debug commands to diagnose the problem.

Thank you,

Hello navellano ,

 

Thanks for your reply ,

DHCP server is available and assigning address , as i mentioned AP itself assigned an ip from same DHCP pool , however client is not assigning an IP . 

I will run some debugs and write it here ,

Hi @qsosan,

 

Is your SSID in tunnel or bridge mode? Have you set the 'Optional VLAN ID' to 5?

Hello hbac ,

 

Yes its in bridge mode and optional vlan was set to 5 ,

The issue resolved after i had set the vlan on data interface to 0 along with optional vlan on SSID to 0 .
