Table 46 VLAN Port Type Descriptions
LABEL DESCRIPTION
Egress Ports A port that is in the egress list in a VLAN. Only select this if the subscriber's
DSL modem or router supports 802.1Q VLAN.
Forbidden Ports A port that is blocked from joining a VLAN group. No frames are transmitted
through this port.
Untagged Ports A port that does not tag all outgoing frames transmitted.
Normal Tagged Port A port that joins a VLAN group using GVRP. Outgoing frames are tagged on
this port.
12.2.2 Removing a VLAN
In the VLAN screen, select a VLAN and click Delete.
12.3 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.
