IEEE 802.1Q VLANs

Parameters
These parameters are displayed:
Edit Member by VLAN
◆ VLAN – ID of configured VLAN (1-4094).
◆ Interface – Displays a list of ports or trunks.
◆ Port – Port Identifier. (Range: 1-12/28)
◆ Trunk – Trunk Identifier. (Range: 1-8/12)
◆ 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 “VLAN
Trunking” on page 131). 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).
