Description
Trunk Identifier. (Range: 1-12)
Indicates VLAN membership mode for an interface. (Default: Access)
Access: Sets the port as an Access VLAN interface. The port transmits
and receives untagged frames on a single VLAN only.
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 untagged frames.
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 and tagged member.
Sets the interface as 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,
Untagged; Default: All)
Acceptalbe Frame Type not supported under access mode.
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.
