The AP does not tag packets with the management interface VLAN. The AP encapsulates the packets from the clients in Lightweight AP Protocol (LWAPP), and then passes the packets on to the WLC. The WLC then strips the LWAPP header and forwards the packets to the gateway with the appropriate VLAN tag. The VLAN tag depends on the WLAN to which the client belongs. The WLC depends on the gateway to route the packets to their destination. In order to be able to pass traffic for multiple VLANs, you must configure the uplink switch as a trunk port.
When the management interface on the controller is configured as part of the 'native vlan' on the switchport to which it connects, the controller should NOT tag the frames. Therefore, you must set the VLAN to be zero (on the controller).
Thanks htarra for the write-ups above. appreciate it.
The uplink of the switch to the controller is already configured as a trunk port with a native vlan set as 3 on the switchport, allowing also the vlan's needed to pass through(Clients & CCTV). And all along it was running with the wlan clients with DHCP. It's just that when we do Vlan Tagging and Ethernet bridging on the RAP's and with static IP's on the camera(cctv)
The Failover to the 2nd WLC seems to be working Fine, but when HA is tweaked(Change the Controller name to point to the 1st WLC) on the 2xRAP's it will cut off the clients(WGB&2xCCTV's).
Correct me if I'm wrong are you suggesting to replace the native vlan (3) and set the VLAN to be zero(0) on the controller? Then that would entail a Downtime on all the WLAN Clients considering it is in production right now.
In Cisco Documentation below they are now using CAPWAP from LWAPP on their version 5.2 software code of the WLC.
