C HAPTER 6 | VLAN Configuration
IEEE 802.1Q VLANs
– 97 –
ES-2000 Series
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.
■
None: Interface is not a member of the VLAN. Packets associated
with this VLAN will not be transmitted by the interface.
N OTE : VLAN 1 is the default untagged VLAN containing all ports on the
switch using Access mode.
