USG+edgeswitch+UAP=troubles

my configuracion:

usg:

• defalut ip(192.168.0.1/24)

• create vlan_10 (teachers) as 10.0.10.1/24

• create vlan_20 (students) as 10.0.20.1/24

edgeswitch:

• vlan_1 default vlan
• vlan_10
• vlan_20

first:

interface 0/23 description 'trunk to USG' vlan participation include 10,20 vlan tagging 1,10,20 exit 

and:

interface 0/21 description 'UAP library' vlan participation exclude 20 vlan participation include 10 vlan tagging 1,10 poe opmode passive24v exit 

also for testing purposes:

interface 0/16 vlan pvid 10 vlan participation exclude 20 vlan participation include 10 exit 

UAP:

• conected to 0/21

currently if a connect my laptop to 0/16 got an 10.0.10.x ip range(works!!), also can see the status of my USG(works!!!) but UAP connected to 0/21 cant be adopted, got an adoption failed. UAP is already adopted and previously configured(same USG).

SOLVED!!!!

update the firmware from 1.0.1 to 1.8 and got "switchport mode trunk" and now the damn thing is working.
