Using VLANs
The TigerCard 1000 network card supports the IEEE 802.1Q VLAN
standard and can be configured to participate in a network with
other devices that use VLANs.
An IEEE 802.1Q VLAN is a group of ports that can be located
anywhere in the network, but communicate as though they belong
to the same physical segment. VLANs help to simplify network
management by allowing you to move devices to a new VLAN
without having to change any connections. VLANs can be easily
organized to reflect departmental groups (such as Marketing or
R&D) or usage groups (such as e-mail or video conferencing).
VLANs provide greater network efficiency by reducing broadcast
traffic, but also allow you to make network changes without having
to update IP addresses or IP subnets. VLANs inherently provide a
high level of network security, since traffic must pass through a
router or a Layer 3 switch to reach a different VLAN. Usually VLANs
are configured within IEEE 802.1Q VLAN-enabled switches in the
network where ports are assigned to specific VLAN IDs.
Note:
The VLAN ID configured within the card must match one of
those in the IEEE 802.1Q-compliant switches throughout the
network.
Traffic Priority
The TigerCard 1000 network card supports the IEEE 802.1p Quality
of Service standard with eight levels of priority. Defining priority
levels in the network card allows it to work with other network
devices to deliver higher priority packets first. Note that the IEEE
802.1p standard must be supported by the other devices in the
network. Refer to the documentation of your network devices for
configuration options on handling frames with priority tags.
