Egress rule
The egress rules stipulate how outgoing data is to be handled by the
Switch.
VLAN identifier
The assignment to a VLAN is effected via a VLAN ID. Every VLAN exist-
ing in a network is identified by an ID. This ID must be unique, i.e. every
ID may only be assigned once in the network.
Port VLAN identifier (PVID)
The management assigns a VLAN ID for every port. This ID is therefore
known as the port VLAN ID. The Switch adds a tag to every data packet
received without a tag. This tag contains a valid VLAN ID. When a data
packet is received with a priority tag, the Switch adds the port VLAN ID.
Member set
The member set is list of the ports belonging to a VLAN. Every VLAN has
a member set.
Untagged set
The untagged set is a list of the ports of a VLAN which send data packets
without a tag. Every VLAN has an untagged set.
GARP - Generic Attribute Registration Protocol

ample, how GVRP information is distributed.

This allows switches to learn VLANs.
