know what tag should be added to the sent packet so that the vlan of the packet is the voice vlan configured for the interface connected to it? This is achieved through the LLDP protocol. The ip Phone Number communicates with the switch through LLDP. The switch sends the voice vlan of the interface to the ip phone number through LLDP protocol. 2. The voice device that does not support tags, for example, Huawei's EchoLife ET65 ip phone sends/receives packets without tags. In this case, the OUI f
