Sir,
I have a simple setup of a switch(3524) and a stand alone AP(1210).
The AP is configured as DHCP server.
The problem is my wireless devices cannot get IP from it and the following messages will prompt up. It cannot receive an IP from DHCP server.
=================
*Mar 1 00:38:24.979: %DOT11-6-ASSOC: Interface Dot11Radio1, Station 5426.960f.9225 Associated KEY_MGMT[NONE]
*Mar 1 00:39:26.060: %DOT11-6-DISASSOC: Interface Dot11Radio1, Deauthenticating Station 5426.960f.9225 Reason: Sending station has left the BSS
=================
However, my PC connected to the switch CAN get IP from the DHCP server without any issue.
The config files of switch and AP are attached for your reference.
Any idea?
Thank you.

Hi, The DHCP is not working via wireless (vlan 10), because there is an no IP address associated with this vlan (BVI10) ... DHCP working via switch, because there is IP address associated with BVI1 (for native vlan), so you are connecting AP to the switch for fa0/1 or fa0/13? Right?
Unfortunately, you can not just type the command:
int bvi10
ip add x.x.x.x x.x.x.x
bridge 10 route ip
If I'm not mistaken, route ip only allowed on bridge group 1... So you need to turn the situation around... Turn VLAN 10 in bridge group 1 and make it a native.
On the AP:
interface Dot11Radio1.10
encapsulation dot1Q 10 native
bridge-group 1
interface FastEthernet0.10
encapsulation dot1Q 10 native
bridge-group 1
interface BVI1
ip address 192.168.102.34 255.255.255.224
bridge 1 route ip
On the switch, on the interface where AP is connected:
interface FastEthernet0/x
switchport trunk native vlan 10
switchport mode trunk
I hope you will understand me, unfortunately English is not my native language, and I can not describe it more easy to understand ...

Hello
Looks like you have specified vlan 10 on the switch and not on the AP -
On the Ap - try chaning the BVI and the bridge-group to 10
no int bvi 1
int bvi 10
ip add 192.168.102.34 255.255.255.224
interface Dot11Radio1
bridge-group 10
bridge 10 protocol ieee
bridge 10 route ip

Hi Paul,
I would assume that he will not be able to remove the BVI1 interface as such. The AP by default may not allow this. So he could remove the ip address from BVI1 interface with "no ip address" command try assigning the same ip address to BVI10.
Hi Joseph,
Which switch port you have your AP connected to? Please configure the switch port where AP is connected as trunk port as i dont see any trunk configuration on your switch port.
Hope that helps.

Najaf

On the AP which is set up as a DHCP server make sure you specify the command, "ip dhcp server" in global configuration mode....

Thank you. You solve the problem for me.
Well, I decide to use the detaul vlan 1 instead of 10 to simpliy the setting. Now it works.
Thank you again.
