9800 controller with point to point bridge will not pass multiple VLAN

[srandolph1]

I am setting up a new 9800 controller. I have followed the Configure Mesh on Catalyst 9800 Wireless
LAN Controllers guide. I have the Bridge configured and functioning. However it will only pass VLAN 10 traffic, it is not passing VLAN 20 or 30. I have enabled VLAN Transparent and ethernet bridging. I have also spent hours reviewing 9800 configuration guide but can not get the other VLAN traffic to pass over the point to point bridge. At this point any help would be great.

 - You can also have the current configuration on the 9800 validated by using  the CLI command : show  tech   wireless , have the output analyzed by  https://cway.cisco.com/tools/WirelessAnalyzer/  , please note do not use classical show tech-support (short version) , use the command denoted in green for Wireless Analyzer.               Checkout all advisories!

1. Check your config as advised by @marce1000 

2. What version of software are you using and what AP?

@rrudrapa  I am running 17.3.5B and using 1562D APs. I will run the config through the analyzer shortly and let both of you know what is finds.

Hello,

To clarify you mentioned you have VLAN Transparent enabled , this enabled will prevent the AP from passing multiple VLANs, this is enabled by default and should only be enabled if you are only using a single vlan.

Please disable this if you want to pass multiple vlans and try again !

I think @Prince.O means disabled by default - but yes well spotted, I agree.

So the solution was that even though I had set the Configuration / Access points / Mesh / Mode to trunk with a native VLAN the APs were not updating correctly. I had to issue the command ap name (XXX) mesh vlan-trunking native 10, from the controller to both APs in the bridge. As soon as I issued that command the bridge started working perfectly.

Had a similar issue and this worked for me:

===============RAP SWITCHPORT CONFIGURATION=============
conf t
int xxx
switchport mode trunk
switchport trunk native vlan x
switchport trunk allowed vlan X, Y
end
wr

==========MAP SWITCHPORT CONFIGURATION================

conf t
int xxx
switchport mode trunk
switchport trunk native vlan x
switchport trunk allowed vlan X, Y
end
wr

=========WLC RAP CONFIGURATION======================
===> ON the WLC
-> Configuration Access Points RAP:
Mesh tab,
Mode Trunk
Native VLAN ID* X
Allowed VLAN IDs Y
VLAN Trunking Native Select Checkbox X
Role Root
Update & Apply to Device

=========WLC MAP CONFIGURATION====================
===> on the WLC:
Mesh tab:
Mode: Trunk
Native VLAN ID*: X
Allowed VLAN IDs: Y
VLAN Trunking Native: Leave Unchecked
Role: Mesh
Update & Apply to Device

==================END=================================
This is working with "VLAN Transparent" and "Ethernet Bridging" Enabled on the Mesh Profile, Advanced tab
