Configuring Operation Modes Of Voice Vlan According To Voice Stream; Supporting Information Of Voice Vlan On Various Ports - Huawei Quidway S3900 Series Operation Manual

Operation Manual – Voice VLAN

1.1.1 Configuring Operation Modes of Voice VLAN according to Voice
Stream
A voice VLAN can operate in two modes: automatic mode and manual mode. You can
configure the operation mode for a voice VLAN according to data stream passing
through the ports of the voice VLAN.
I. Processing mode of untag packets sent by IP voice devices
In automatic mode: S3900 series switches automatically add a port connecting a
IP voice device to the voice VLAN through learning the source MAC address in the
untag packet sent by the IP voice device when it is powered on. When the aging
time of a port expires, voice ports on which the OUI addresses are not updated (no
voice stream passes) will be automatically removed from the voice VLAN; voice
ports can not be added into or removed from the voice VLAN through manual
configurations.
In manual mode: you need to execute related configuration commands to add a
voice port to the voice VLAN or remove a voice port from the voice VLAN.
II. Processing mode of tag packets sent by IP voice devices
For tag packets sent by the IP voice devices, processing modes in the two modes are
the same, that is, a packet will be forwarded in the corresponding VLAN according to
the VLAN ID attached in the packet.
Note:
An untag packet refers to the packet without VLAN tag.
A tag packet refers to the packet with VLAN tag.

1.1.2 Supporting Information of Voice VLAN on Various Ports

Voice VLAN packets can be forwarded by trunk ports and hybrid ports in voice VLAN.
You can enable a trunk port or a hybrid port belonging to other VLANs to forward voice
and service packets simultaneously by enabling the voice VLAN function for it.
As multiple types of IP voice devices exist, you need to match port mode with types of
voice stream sent by IP voice devices, as listed in Table 1-2.
