Protocol Vlan - D-Link xStack DES-3800 Series User Manual

Protocol VLAN

The DES -3800 Switch Series incorporates the idea of protocol-based VLANs. This standard, defined by the IEEE 802.1v
standard maps packets to protocol-defined VLANs by examining the type octet within the packet header to discover the type of
protocol associated with it. After assessing the protocol, the Switch will forward the packets to all ports within the protocol-
assigned VLAN. This feature will benefit the administrator by better balancing load sharing and enhancing traffic classification.
The Switch supports fourteen (14) pre-defined protocols for configuration. The user may also choose a protocol that is not one of
the fourteen defined protocols by properly configuring the userDefined protocol VLAN. The supported protocols for the protocol
VLAN function on this switch include IP, IPX, DEC LAT, SNAP, NetBIOS, AppleTalk, XNS, SNA, IPv6, RARP and VINES.
The following is a list of type headers for each protocol listed for VLAN configuration.
In configuring the user-defined protocol, the administrator must make sure that the pre-defined user type header does not match
any other type header. A match may cause discrepancies within the local network and failure to define the VLAN to which to
forward packets.
