IEEE 802.1Q VLANs
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.
Membership Type – Select VLAN membership for each interface by
◆
marking the appropriate radio button for a port or trunk:
Tagged: 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.
Untagged: 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.
Forbidden: Interface is forbidden from automatically joining the
■
VLAN via GVRP. For more information, see "Automatic VLAN
Registration" on page 177.
None: Interface is not a member of the VLAN. Packets associated
■
with this VLAN will not be transmitted by the interface.
VLAN 1 is the default untagged VLAN containing all ports on the
N :
OTE
switch.
Edit Member by Interface
All parameters are the same as those described under the preceding
section for Edit Member by VLAN.
Edit Member by Interface Range
All parameters are the same as those described under the earlier section
for Edit Member by VLAN, except for the items shown below.
Port Range – Displays a list of ports. (Range: 1-12)
◆
Trunk Range – Displays a list of ports. (Range: 1-12)
◆
The PVID, acceptable frame type, and ingress filtering parameters
N :
OTE
for each interface within the specified range must be configured on either
the Edit Member by VLAN or Edit Member by Interface page.
