Protocol Vlans - D-Link DGS-3324SRi User Manual

Protocol VLANs

The xStack family of switches 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 fifteen (15) pre -defined protocols for configuration. The user may also choose a
protocol that is not one of the fifteen defined protocols by properly configuring the userDefined protocol VLAN. The
supported protocols for the protocol VLAN function on this switch include IP, IPX, DEC, 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
forward packets to.
