identify the source VLAN. Note that frames belonging to the port's default
VLAN (i.e., associated with the PVID) are also transmitted as tagged frames.
◆
PVID – VLAN ID assigned to untagged frames received on the interface.
(Default: 1)
When using Access mode, and an interface is assigned to a new VLAN, its PVID
is automatically set to the identifier for that VLAN. When using Hybrid mode,
the PVID for an interface can be set to any VLAN for which it is an untagged
member.
◆
Acceptable Frame Type – Sets the interface to accept all frame types,
including tagged or untagged frames, or only tagged frames. When set to
receive all frame types, any received frames that are untagged are assigned to
the default VLAN. (Options: All, Tagged; Default: All)
◆
Ingress Filtering – Determines how to process frames tagged for VLANs for
which the ingress port is not a member. (Default: Enabled)
■ 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.
◆
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 cannot be included as a member of the VLAN.
■
None: Interface is not a member of the VLAN. Packets associated with this
■
VLAN will not be transmitted by the interface.
Note: VLAN 1 is the default untagged VLAN containing all ports on the switch
using Hybrid mode.
