Vlan And Trunk Groups; Protocol Vlans - D-Link Xstack DGS-3300 Series User Manual

xStack DGS/DXS-3300 Series Layer 3 Stackable Gigabit Ethernet Switch User Manual

VLAN and Trunk Groups

The members of a trunk group have the same VLAN setting. Any VLAN setting on the members of a trunk group will
apply to the other member ports.

Protocol VLANs

The xStack DGS/DXS-3300 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 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.
NOTE: In order to use VLAN segmentation in conjunction with port trunk
groups, first set the port trunk group(s), and then the user may configure
VLAN settings. If changing the port trunk grouping with VLANs already in
place, the user does not need to reconfigure the VLAN settings after
changing the port trunk group settings. VLAN settings will automatically
change in conjunction with the change of the port trunk group settings.
