What should be ideal AP connected swich port configuration? We have configured below config in our environment but sometimes facing issues due to same. Please confirm if there is any issue with below config.

Access point Interfaces

Local model Access points

interface GigabitEthernet <interface id>

description wireless_ap

spanning-tree portfast

switchport

switchport mode access

switchport access vlan 90

logging event link-status

logging event power-inline-status

service-policy output AutoQos-4.0-Output-Policy

no shutdown

Flex connect Access points (with Local Switching)

description wireless access point

switchport

switchport trunk encapsulation dot1q

switchport trunk native vlan 90

switchport trunk allowed vlan 90,40, 50-59,78

switchport mode trunk

logging event link-status

logging event power-inline-status

spanning-tree portfast trunk

service-policy input AutoQos-4.0-CiscoPhone-Input-Policy

service-policy output AutoQos-4.0-Output-Policy

no shutdown

That should be ok - personally i remove auto QOS and test it

what kind of problem ?

Also you have some other VLAN other than 40, in the trunk what are that VLAN for ?

make sure layer 2 spanning  correctly (if you have STP root some where ?)

Agree to @balaji.bandi by removing AutoQoS line if you don't have end-2-end QoS configured from endpoint to the WAN router, and giving us additional information about the issues you are facing.

Those configurations are the basic ones for APs in local and Flexconnect mode so no problem on that.

I will recommend you to review the IOS code the switch is running (seems to be pretty old switch due to the fact tha you need to set the encapsulation piece) and the trunk port oversubscription. Additionally, as you are not mentioning the AP model you are using, and supposing you are using a mid/high-end enterprise model, check whether your switch do support PoE+, otherwise you can notice weird behaviours like disconnections, or low performance due to AP disabling some radios/streams.
