Spanning-Tree Portfast Trunk for APs

allanhedegaard — Mon, 05 Jul 2021 15:07:44 GMT

I have 8 mobility express enabled AP's that are running on my network. They are of course configured on trunk ports (Management, SSID 1, SSID 2 etc.)

Currently we seeing some general client connectivity issues (short disconnects)

I have a feeling that this issue, is due to a lot of interference and noise in the environment - and that this pollution is causing my clients to roam a lot between the eight APs.

Something tells me that I should configure the switch uplink ports with switchport portfast trunk in order for clients to onboard quickly. Can anyone confirm this theory?

I dont think it will resolve your issue.

as far my knowledge... If you want to make a trunk port become Forwarding imediately after coming up, you need the spanning-tree porfast trunk command.

Rather you should do the proper site survey and check the cause of noise and interference.

Hi,

Switchport fast would help only for the AP registration.

For client roaming issues you need to focous on the AP cell coverage, AP/WLC configuration and the coverage requirments of the client equipments.

I would suggest these articles:
