Configuring the Switch

48-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet
Ingress filtering Determines how to process frames
tagged for VLANs for which the ingress port is not a
member. (Default: Disabled)
Ingress filtering only affects tagged frames.
If ingress filtering is disabled and a port receives frames
tagged for VLANs for which it is not a member, these
frames will be flooded to all other ports (except for those
VLANs explicitly forbidden on this port).
If ingress filtering is enabled and a port receives frames
tagged for VLANs for which it is not a member, these
frames will be discarded.
Ingress filtering does not affect VLAN independent BPDU
frames, such as GVRP or STP. However, they do affect VLAN
dependent BPDU frames, such as GMRP.
Fill in the required settings for each interface, then click
Save Changes.
VLAN Management > Ports to VLAN
Use the Ports to VLAN screen to configure port members
for the selected VLAN index. Assign ports as tagged if
they are connected to 802.1Q VLAN compliant devices,
or untagged they are not connected to any VLAN-aware
devices.
VLAN Management > Ports to VLAN
Switch Port Mode Indicates VLAN membership mode
for an interface. (Default: Access)
Access Is the default setting for all ports. The port is a
member of a single, untagged VLAN.
Trunk Specifies a port as an end-point for a VLAN
trunk. A trunk is a direct link between two switches,
so the port transmits tagged frames that identify
the source VLAN. Note that frames belonging to the
port’s default VLAN (that is, associated with the PVID)
are transmitted as untagged frames. If the PVID is
associated with a VLAN ID other than 1, then the
frames are tagged.
General Specifies a hybrid VLAN interface. The port
may transmit tagged or untagged frames.
Membership Select VLAN membership for each interface
by selecting the appropriate option for a port or LAG:
Excluded The interface is forbidden from joining the
VLAN.
Untagged The interface is a member of the VLAN. All
packets transmitted by the port will be untagged, that
is, not carry a tag and therefore not carry VLAN or CoS
information. Note that an interface must be assigned
to at least one group as an untagged port.
Tagged The interface is a member of the VLAN.
All packets transmitted by the port will be tagged,
that is, carry a tag and therefore carry VLAN or CoS
information.

selected interface.
