VLAN Operation
The VLAN’s are setup by programming the VLAN Mask Registers in the “EEPROM Memory Map” section. The
perspective of the VLAN is from the input port and which output ports it sees directly through the switch. For example
if port 1 only participated in a VLAN with ports 2 and 8 then one would set bits 0 and 6 in register 13 (Port 1 VLAN
Mask Register). Note that different ports can be setup independently. An example of this would be where a router is
connected to port 8 and each of the other ports would work autonomously. In this configuration ports 1 through 7
would only set the mask for port 8 and port 8 would set the mask for ports 1 through 7. In this way the router could
see all ports and each of the other individual ports would only communicate with the router.
All multicast and broadcast frames adhere to the VLAN configuration. Unicast frame treatment is a function of
register 2 bit 0. If this bit is set then unicast frames only see ports within their VLAN. If this bit is cleared unicast
frames can traverse VLAN’s.
VLAN tags can be added or removed on a per port basis. Further, there are provisions to specify the tag value to be
inserted on a per port basis.
The table below briefly summarizes VLAN features. For more detailed settings see “EEPROM Memory Map” section.
