C3650 when switched from access port to trunk port AP loses Vlan1

rick lancaster
Level 1
Level 1

I am having issues with C3650's in MDF's (4) that when I change from an access port to a trunk port the ap will lose access to VLAN 1 native. when in trunk mode I can access Vlan 60 guest wifi and not Vlan 1 secure wifi. What is crazy is the 2960's that link up to the 3650's are working giving access to VLAN 1 and VLAN 60 in truck mode.

I have talked to TAC support for 4 hours and nothing. I have talked to wifi support for 6 hours and nothing.

 

here is the config for 3650

I see in the 3650 you have the line:
vlan dot1q tag native
