Vlan Settings - D-Link DIR-100 User Manual

DIR-100 Triple Play Router

VLAN Settings

The ports labeled VLAN on the Router, ports 1 and 2, are pre-configured for VLAN and 802.1p priority
settings intended to support value added service like VoIP/Video streaming. The VLAN ports, ports 1 and 2,
can also be configured separately for priority and VLANs if desired. The NAT ports 3 and 4 are configured
in tandem, they have identical PVID (Port VLAN Identifier) and 802.1p priority settings.

The port VLAN identifier or PVID is used to indicate membership of the port-based VLAN. VLAN
membership in conjunction with priority setting can be used to expedite time sensitive data frames such as
video or audio streaming from media servers etc. If the DIR-100 is used on a network with other VLAN
supporting devices, such as 802.1Q VLAN switches, it is important to make certain that all the ports on these
switches used for VoIP or streaming video are on the same VLAN, that is use the same PVID, and have
identical 802.1p priority settings.
The 802.1p Priority setting for the VLAN ports are used to give high priority to properly 802.1p tagged data
frames passing through the port. Since the primary function of these ports is to support voice, audio and
video network applications and hardware, the priority setting should be high. Priority tags are given values
from 0 to 7 with 0 being assigned to the lowest priority data and 7 assigned to the highest.
The Management PVID is used to identify the VLAN from which management instructions are sent. For
example, management of a multicast VLAN set up on the network might have a designated management
VLAN. This is where IGMP snooping and other broadcast/multicast control and information packets will
originate when properly configured on switches that support such management.
