what is native vlan for FlexConnect Mode AP ?

[sh-door]

For flex mode, I understand that i use the 802.1q trunking method to tag specific vlan.

I understand that when I use the ap as flexmode, I need to set the port to native vlan trunk.

When I set up a native vlan on an ap connection port, I wonder what vlan I should set up.

Most documents say that management vlan should be set to native vlan, but I don't know what management vlan is

 statically give a ip to the ap, and that ip band is the vlan 20 band on the backbone and the gateway is the backbone hsrp.

The management band of the WLC is the vlan 10 band, The user SSID band to be used in ap is vlan 30.

What is the basis for designating the native vlan ? 

I think it's vlan 20 or 10, but I don't really understand this clearly.

I found the answer to this question

When ap mode  flexconnect, setting the native vlan to the ap was based on the ip address band of the AP !

When they say management, typically folks create a subnet just for the wireless ap's.  That is what they call management "for wireless" network.  It would be the same for servers, you might have dedicated vlans for them, dedicated vlans for your switches and routes, etc. AP's just require no vlan tagging, which of course in a trunk means Native vlan.
