Title: VWLC DHCP Issue
Post by: Mikep 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?

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

Post by: MC on January 26, 2016, 09:26:54 PM: 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.
