Security Mode And Normal Mode Of Voice Vlans - HP V1910 Switch Series User Manual

 In manual mode, you need to manually assign an IP phone accessing port to a voice VLAN. Then,
the system matches the source MAC addresses carried in the packets against the device's OUI
addresses. If a match is found, the system issues ACL rules and configures the packet precedence.
In this mode, assigning ports to and removing ports from a voice VLAN are performed manually.
Both modes forward tagged packets according to their tags.
Table 59 lists the relationships between the voice assignment VLAN mode, the voice traffic type of an IP
phone, and the port link type.

NOTE:
If an IP phone sends tagged voice traffic and its accessing port is configured with 802.1X authentication
and guest VLAN, you must assign different VLAN IDs for the voice VLAN, the port VLAN ID (PVID) of
the accessing port, and the 802.1X guest VLAN.
If an IP phone sends untagged voice traffic, to implement the voice VLAN feature, you must configure the
PVID of the IP phone's accessing port as the voice VLAN. As a result, 802.1X authentication cannot be
implemented.

Security mode and normal mode of voice VLANs

Depending on their inbound packet filtering mechanisms, voice VLAN-enabled port can operate in the

ensure that the PVID of
the port has been
created and is not the
voice VLAN and the
traffic of the PVID can
pass through the port.

configure the PVID of
the port as the voice

port to allow the traffic
of the voice VLAN to
pass through.

configure the PVID of the port
as the voice VLAN and
configure the port to allow
the traffic of the voice VLAN
to pass through untagged.
