IF RouteBorad's switch port can do PVID ?

I do the wifi , 8AP 1AC

1AC+6AP—SWITCH------TRUNK----RB750Gr3—2AP

I want vlan2 to do the management-vlan (for AP and AC)
so I set the switch’s ports (which conn with AP&AC) mode trunk and pvid 2 ,and , AC can find the AP ,this is no problem

but the ap (conn -to rb750g) can’t be found, because i dont know how to set the rb750g’s port PVID…

the end , i give up to use vlan 2 for management ,switch’s ports set PVID vlan 1, then AC can find all the AP, network is ok

SO anybody mis this question, or if the rb750g can set port PVID ? tell me thanks

rb750g - switch - port
show this

name switch vlan-mode vlan-header default-vlan-ID
ether1 switch1 disabled leave as is 0
ether2 switch1 disabled leave as is 0
ether3 switch1 disabled leave as is 0
ether4 switch1 disabled leave as is 0
ether5 switch1 disabled leave as is 0

and i set ether3 (conn to AP) default-vlan-id 2
but it is not working, AC cant find the AP

rb750g - switch - port
show this

name switch vlan-mode vlan-header default-vlan-ID
ether1 switch1 disabled leave as is 0
ether2 switch1 disabled leave as is 0
ether3 switch1 disabled leave as is 0
ether4 switch1 disabled leave as is 0
ether5 switch1 disabled leave as is 0

and i set ether3 (conn to AP) default-vlan-id 2
but it is not working, AC cant find the AP

solved

must use the bridge

bridge ports add the ether

on bridge vlans add the vlan

and set the vlan taget on the bridge

and set the vlan untaget on which ether port ,or taget on which ether port
