Flexconnect, branch and central site have same VLAN's

[Thomasvdk]

Is anyone familiar with a flexconnect deployment where on the central and branch site the same VLAN's are in use?

On both sites the following VLAN's are in place:

VLAN 32 = BYOD

VLAN 31 = USER

VLAN 40 = VOICE

On the branch site I want to deploy Flexconnect. When creating the VLAN mapping in the AP configuration all the VLAN's are instantly assigned. For local branch DHCP ip-helper addresses are configured on the branch switch. When a client connects to the Flexconnect AP it doesn't get an IP address. Suggestions?

7 days and still no response, this must be quite unique :)

Have you configured AP management vlan as native vlan on the trunkport where AP connected ? As long as vlan mapping is correct you should able to get IP.

Hi Thomas,

On the WLC location, your clients get IP? How did you setup the DHCP Server: on interface level or DHCP Override?

For the FlexConnect sites:

 - enable Vlan Support?

 - specify Native Vlan for the AP mgmt Vlan

 - add Vlan Mapping: Wlan to sites's Vlan

 - finally: configure accordingly the switchport:

 switchport mode trunk

 switchport trunk native vlan ...

 switchport trunk allowed vlan all
