We have a building with the WAN link etc. There is a separate building which is connected via a point to point wireless link.
We have Cisco 2960 switches at either end of the wireless link. The switch is divided into 2 vlans one for telephony and one for data. with links in the main building going into a netgear switch.
In the separate building we can access the data vlan but not the voice. The ports connecting to the wireless link are trunked and if I create a vlan in the main building it replicates to the separate building and the ports are a member of the correct VLAN.
I tested with the switches connected directly together and was fine so presuming something related to the wireless link, any thoughts welcome!!
In the case I would connect 2 building with routers, I mean running /29 subnet for inter-builing routing. This won't allow you to have single L2 subnet between building, but this might be not an issue in your case.
PS: otherwise you need to enable your wireless to transfer several VLANs; not sure if your AP supports this.
1. Your data VLAN is the native VLAN on the trunk ports
With that in mind you probably have an MTU issue:
In trunk ports your native VLAN (Default VLAN 1, probably your data VLAN) will not be tagged so MTU=1500,
your voice VLAN will be tagged so MTU > 1500 and your wireless equipment can't handle >1500 MTU so it drops the packets. You can confirm this by changing the native VLAN on your trunk ports to the voice VLAN and see if it works. If that's your case then either change the MTU on your wireless equipment or use 2 wireless links in non trunk ports 1 for each VLAN.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
