From log i know that 802.1x passed, while dhcp don't send ip address. It seems that the local vlan id is 0 while in reality is 3... WHY ? i don't understand.

Someone can help me to find the problem? i think the problem is on the network, the dhcp ( the corporate router) is directly connected to the ap.

Re: client not receive ip address - dhcp_reqd

you are using internal or external dhcp server ???

did you enabled dhcp proxy ??

if not :

via GUI:

Controller->Advanced->DHCP 

via the CLI:

Config dhcp proxy enable

we use an external dhcp (the router of AP) ,dhcp proxy is disabled, work in bridge mode.

Re: client not receive ip address - dhcp_reqd

did you used this command on layer 3 device.

Switch#conf t
Switch(config)#interface vlan 
Switch(config-if)#ip helper-address

the other wlan client receive ip address from dhcp. WLAN 103 is mapped with vlan 3 but on log appear vlan 0:

IPv4 ACL ID = 255,

client not receive ip address - dhcp_reqd

Are you setting your FlexConnect native vlan and the wlan to vlan mapping?  You also need to make sure you have the ip helpers setup and that dhcp is working.  I would configure a switch port to a vlan that the wireless users is suppose to be on locally at that site and connect a laptop to that port and make sure that the laptop gets an address.

Yea to add to Scoots response. Flex connect local, all your DHCP happens at the switch not the controller.

client not receive ip address - dhcp_reqd

HI

the strange thing is that the VLAN is mapped correctly on the configuration of the AP:

WLAN 103 > VLAN 3

but on log appear vlan 0 !!!

my dhcp is the router directly connected, so do not use ip helper address, other WLAN work....

i must test a wired client...

client not receive ip address - dhcp_reqd

If the AP and the users are on the same vlan, vlan 3, then you can have that switchport as an access vlan 3,  IF they are different, then you need to set the switchport as a trunk.  Test with a wired PC to verify that it works... test on the same switch as the AP also.

Thanks,

Scott

client not receive ip address - dhcp_reqd

The ap is not a 1600 but a 1242 bgn (flex connect local switching). I tested one client on a wired side and receive all the time ip address from dhcp. After reboot the switch, router and ap the problem occurs on another WLAN. The problem is not systematic on the same wlan. For testing purpose i turned off the secondary switch/router and the problem persist. I removed the flag to deny static addressing, and the problem persist.

someone can help me ?

client not receive ip address - dhcp_reqd

i checked the trunk on ap side, switch side and router side, is configured correctly, one vlan is native (for management) and the other tagged.

client not receive ip address - dhcp_reqd

SOLVED

This is a bug with flexconnect and native vlan 2 for management (only), with other vlan i can't find that problem.

DON'T USE VLAN 2 WITH FLEXCONNECT ON AP 1242 WITH RELEASE MINOR TO 7.6, ON 7.4 WAS SOLVED ON BETA RELEASE.

this is a bug:
