CONFIGURING THE NETWORK CARD

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.
