Traffic getting tagged with unexpected VLAN id

I'm having trouble with configuring a Cisco WS-C3560V2-24PS-S. Traffic is being tagged with an unexpected VLAN id.

 

I have the following VLAN config on the Switch: 

 

interface Vlan1
 no ip address
 shutdown
!
interface Vlan110
 ip address 192.168.11.254 255.255.255.0
 ip helper-address 192.168.1.25
!
interface Vlan111
 ip address 10.0.1.254 255.255.255.0
 ip access-group 100 in
 ip helper-address 192.168.1.25
!
interface Vlan510
 description Data_Subnet
 ip address 192.168.1.254 255.255.255.0
!
interface Vlan511
 description Voice_subnet
 ip address 172.17.3.254 255.255.255.0

VLAN 111 has an access list, as it is used for a Guest Wifi network:

access-list 100 remark GAST-WIFI
access-list 100 permit ip any host 192.168.1.252 <---(Meraki MX84)
access-list 100 permit udp any any eq bootpc
access-list 100 permit udp any any eq bootps
access-list 100 deny   ip any 192.168.0.0 0.0.255.255
access-list 100 deny   ip any 172.0.0.0 0.240.255.255
access-list 100 permit ip any any

I have a UbiQuiti AP attached to port 23 on the switch. It sends out 2 networks in 2 different VLAN's:

- Corporate Wifi (VLAN 110)

- Guest Wifi (VLAN 111)

 

Clients can connect to the Guest Wifi, and get an IP address. However they do not have internet access, in the logging of our Meraki I see that the traffic is getting taged with VLAN 510:

 

Time (CET) [Sorting down]
Client Event type Details
Nov 5 16:48:14 10.0.1.129 Source IP and/or VLAN mismatch source_client_ip: 10.0.1.129, source_client_mac: E8:40:40:05:15:41, source_client_assigned_vlan: 510  more »

 

The switchport has the following config:

interface FastEthernet0/23
 description WIFI_ZENDERS_UBI
 switchport access vlan 110
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport nonegotiate
 spanning-tree portfast

Any idea why the traffic is getting tagged with 510 ?

Hello

Is vlan 510 residing on the MX?

Does your MX lan port allow all vlans?

The Meraki resides in VLAN 510. His LAN port is tagged in 510

I just changed it to trunk, and allowed all vlans's to no avail.
