IEEE 802.1Q VLANs
34
• 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: 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.
• 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
721 .
• 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.
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)
NOTE
The PVID, acceptable frame type, and ingress filtering parameters for each interface within the
specified range must be configured on either the Edit Member by VLAN or Edit Member by Interface
page.
