Support Tag-based VLAN (IEEE 802.1Q VLAN)
Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a
VLAN across devices from different switch venders. IEEE 802.1Q VLAN uses a technique to insert
a “tag” into the Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the VLAN
numbers.
Support Protocol-based VLAN
In order for an end station to send packets to different VLANs, it has to be either capable of tagging
packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable of classifying
and tagging the packets with a different VLAN ID based not only on the default PVID but also other
information about the packet, such as the protocol.
The NP2624M switch will support protocol-based VLAN classification by means of built-in
knowledge of layer 2 packet formats used by selected popular protocols, such as Novell IPX and
AppleTalk’s Ether Talk, and some degree of programmable protocol matching capability.
