The following table describes the labels in this screen for each VLAN port type.
14.10.3 Introduction to Port-based VLANs
Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port.
Therefore, if you wish to allow two subscriber ports to talk to each other, for
example, between conference rooms in a hotel, you must define the egress (an
egress port is an outgoing port, that is, a port through which a data packet leaves)
for both ports.
Port-based VLANs are specific only to the switch on which they were created.
The port-based VLAN setup screen is shown next. The CPU management port
forms a VLAN with all Ethernet ports.
