VLAN problems on managed Cisco switch.

So, I'm having a weird issue with a Cisco switch. I am using Aerohive APs and they use different SSIDs that communicate over several VLANS. For some reason, they are only able to communicate over one SSID on one VLAN. It doesn't even recognize the others. It appears as though the ports on the switch are setup the same as other switches that also have those VLANS/APs. Has anyone else experienced this?

Here is an example of the configuration of an AP port:

switchport mode trunk
switchport trunk allowed vlan (lists VLANs allowed here)
switchport trunk native vlan (VLAN number here)

The VLANs themselves are also configured on the switch along with the helper IP addresses that correspond to them.

The switch is using VTP version 2 with the correct domain listed. The switch is showing that it was configured by the correct VTP server, but not since March.

Model: WS-C2960S-24PS-L

Anyone have any thoughts?

When you are trunking you are making sure the equipment on the other side of the trunk is accepting and passing VLAN tags.

My first suggestion is to draw this out on visio and post it here. This will give us some things to work with. Also get more techincal with the description of the network layout.

Are the AP's connecting to 1 VLAN per node? Is each node set to a specific number of SSID's that are set in the controller with the appropriate VLAN?

Try this.

switchport mode general
switchport general allowed vlan add (vlans here) untagged.
switchport general native vlan add (should be your management VLAN)

Here is an example of a trunk port I build the other day

interface ethernet 1/24
switchport allowed vlan add 1 untagged
switchport native vlan 1
switchport acceptable-frame-types tagged
switchport allowed vlan add 4-5,10,16,18,20,4093 tagged

 

create vlan interface using command line

Sorry, I thought this was a spelling error.

Since I have no experience with this subject, I suggest you ask Google like so:
