Chapter 5 | VLAN Configuration
IEEE 802.1Q VLANs
– 142 –
■
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
137.
■
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.
Edit Member by Interface
All parameters are the same as those described under the preceding section for
Edit Member by VLAN.
Edit Member by Interface Range
All parameters are the same as those described under the earlier section for Edit
Member by VLAN, except for the items shown below.
◆ Port Range – Displays a list of ports. (Range: 1-12/28)
◆ Trunk Range – Displays a list of ports. (Range: 1-8/12)
Note: The PVID, acceptable frame type, and ingress filtering parameters for each
interface within the specified range must be configured on either the Modify VLAN
and Member Ports or Edit Member by Interface page.
