i was looking quickly into spanning tree integration of the 440x with a wired switches but did not set a test yet. Maybe you already know if it's a vlan stp or port based spanning tree what they coded. Have you got any experience in the operation of the STP? Thanks in advance for your feedback.
Your best bet is to leave the STP settings on the WLC as the defaults. You will config the switch ports that connect to the WLC as 802.1q trunks. The 4402 & 4404 both support LAG which will allow you to use etherchannel between the switch and the WLC.
Do you have a need for the WLC to participate in STP?
thank you for your feedback according stp in 440x switches. Indeed the feature is not critical but i checked it again by mirroring the ports and it is not 'talking' with per vlan STP of 3560 or 3750. From the integration point of view you're right and we'll usually have LAG in place. Thanks for your input.
