IEEE 802.1Q VLANs
•
Port – Port Identifier. (Range: 1-12)
•
Trunk – Trunk Identifier. (Range: 1-12)
•
Mode – Indicates VLAN membership mode for an interface. (Default: Hybrid)
•
Access - Sets the port to operate as an untagged interface. The port transmits and
receives untagged frames on a single VLAN only.
Access mode is mutually exclusive with VLAN trunking (see
If VLAN trunking is enabled on an interface, then that interface cannot be set to access
mode, and vice versa.
•
Hybrid – Specifies a hybrid VLAN interface. The port may transmit tagged or untagged
frames.
•
1Q 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 (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: 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
750
.
•
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.
