My configuration is: Avaya, core swtch and small TP-Link switch
Avaya is connected to the core, tp-link connected to to the core - port on core is setup as TRUNK
I have two VLAN - VLAN 3 for computers and VLAN116 for AVAYA
Computers are connected to the phones, phones connected to core and got IP for VLAN 3, phones got IP for VLAN 116

First port on TP-Link is setup asTRUNK, two VLAN 3 and 116 are created.
I have no idea how to setup this small switch for voice vlan similar like cisco. Tried random configuration and always desktop and phone have the same ip range.

interface gigabitEthernet 1/0/6
switchport mode general
switchport general allowed vlan 3,116 untagged
switchport pvid 116

On core switch I have configured some ports like below and there is no problem with two diffrent IP's, one for phone another IP for desktop from other VLAN

interface GigabitEthernet1/0/38
description ### PC's & IP PHONES ###
switchport access vlan 3
switchport mode access
switchport voice vlan 116

Any ideas?
