VWLC DHCP Issue
« on: January 19, 2016, 06:33:51 PM »
When I join the AP, get an IP from the DHCP scope of the VLAN my AP is in not of the vlan I have set to the interface associated to WLAN. Under the clients tab I see this...



So my first thought was it wasn't picking up the VLAN tag.  So I went into the flex connect options on the AP and checked the vlan support box.

Now it looks like it's getting the vlan info, but DHCP won't work.



Has anyone else run into this?

Are you running FlexConnect with local switching on the WLAN? Who is the DHCP server? What VLAN is mapped to the WLAN and what does you switchport config looks like?

Flex connect with local switching is enabled.
The DCHP server is the Switch. I have the DHCP server on the interface set to the SVI of the switch.
VLAN mapped is vlan 64

Assuming your WLAN is mapped to VLAN64, you interface fa0/3 should be a trunk port allowing vlan 70 (assuming for AP mgmt) and vlan 64.
