IEEE 802.1Q VLANs

PARAMETERS
These parameters are displayed in the web interface:
Edit Member by VLAN
◆ VLAN – ID of configured VLAN (1-4093).
◆ Interface – Displays a list of ports or trunks.
◆ Port – Port Identifier. (Range: 1-24)
◆ Trunk – Trunk Identifier. (Range: 1-32)
◆ Mode – Indicates VLAN membership mode for an interface.
(Default: Hybrid)
â–
Hybrid – Specifies a hybrid VLAN interface. The port may transmit
tagged or untagged frames.
â–
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)
If an interface is not a member of VLAN 1 and you assign its PVID to
this VLAN, the interface will automatically be added to VLAN 1 as an
untagged member. For all other VLANs, the PVID must be defined first,
then the status of the VLAN can be configured as a tagged or 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)
â–
Ingress filtering only affects tagged frames.
â–
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).
â–
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.
