WLC & Swich vlan-int communication issues

Hello,

I have a Cisco-Switch configured with 3-VLANs (1,3 & 6) .  im using VLAN-1 as the management vlan for communication between WLC & Switch.

I have 1-management interface and 2-dynamic interfaces created on WLC.  management-int is using untagged vlan.  and from the Cisco-Switch i can ping WLC Management-int ip.  but i can not ping other WLC Dynamic-interfaces,  while all the subnets-ips are configured properly.  also wifi clients can not connect through those dynamic-interfaces ssids

can any one help please,  here is some config outputs from my WLC >>>>>>>>>>>>>>>>>

WLC & Swich vlan-int communication issues

You are configuring the port as acces port:

>> switchport mode access

remove the above command and replace it with:

>> switchport mode trunk.

Show us the switchport config.

You must have a trunk with all VLANs on the WLC allowed.

I noticed that you are not enabling LAG. it is recommended to enable it.
