Confusing VLAN Tagging with multiple cisco Switches

[s3itesser]

Hello,

may someone can help me. I'm struggeling since 3 days with our VLAN configuration. I don't know where is my error in reasing.

Attached is out networktopolgy. Problem: I've no connection to the WLAN APs on Switch 1 and 4. WLAN on Switch 2 (where also the routers connected) works perfectly) Whats wrong with the configuration/Tagging?

Hopefully someone can help me!

Regards HES

Hi

Pls share switches configurations and also network diagram with switches names.

Names are from up to down 1-4. What configuration do you need? All Ports marked as trunks.

oh man I've found my fault: I had a second cable from switch 2-->3 both ports where untagged -.-

Thanks!

Have you looked into VTP at all as of yet? Also, are the ports to the APs trunked as well? If you can provide the switch configs that would be helpful.
