8.2.3 VLAN Port
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.
Use this screen to view the Switch’s VLAN port settings. Click Monitor > VLAN > VLAN > VLAN

Each field is described in the following table.
Accept Frame
Type
This field displays the type that is accepted by the frame.
Specifes the type of frames allowed on a port. Choices are All, Tag Only and Untag
Only. All accepts all untagged or tagged frames on this port. This is the default
setting. Tag Only accepts only tagged frames on this port. All untagged frames will be
dropped. Untag Only accepts only untagged frames on this port. All tagged frames will
be dropped.
Ingress Filter If set, the Switch discards incoming frames for VLANs that do not have this port as a
member.
VLAN Trunks Enable VLAN Trunking on ports connected to other switches or routers (but not ports
directly connected to end users) to allow frames belonging to unknown VLAN groups to
pass through the Switch.
