I understand that it is Possible to permit 1 Data VLAN and 1 Voice VLAN per Access Port. Would be willing to learn other wise.
Out of curiosity May i request you to show me the Output for
sh int GigabitEthernet1/0/19 trunk
Is there a reason why you want to have the connection to switch BF-TL-SW03 be an access connection?
It would be best to have that as a trunk link.
I guess that you would want to setup dot.1q mode(QinQ) in this interface, do you? If yes, you can configure this interface like the below:
interface GigabitEthernet1/0/19 description daisy-chain Connection to switch BF-TL-SW03 switchport access vlan 20 switchport mode dot1q-tunnel storm-control broadcast level 2.00 1.00 storm-control action trap
And you also need configure interface connected to G1/0/19 ON BF-TL-SW03
interface GigabitEthernet x/x/x switchport mode trunk switchport trunk allowed vlan 10,11,15,20,25,30,100
