• Isolated
An isolated port has complete Layer 2 isolation from the other ports within
the same PVLAN, but not from the promiscuous ports. Isolated ports can
communicate with promiscuous ports.
In the factory default configuration, all ports are designated as Access ports,
and are associated with the default VLAN.
Acceptable Frame Type
The acceptable frame type can be set on a port to accept all frames (tagged
and untagged), tagged only, or untagged only. This setting takes precedence
over all other settings, so that if the acceptable frame type is tagged only,
incoming untagged frames are silently discarded, even if the port has a valid
PVID.
VLAN Membership
The device supports up to 2-4094 VLANs.
Ports are assigned to a VLAN in the Port Settings pages.
To view the ports in a VLAN, and assign various parameters:
1 Click Switching > VLAN > VLAN Membership in the tree view to
display the VLAN Membership: Summary page.
The ports in the selected unit/VLAN are displayed along with their
statuses.
Each port/LAG is labeled with one of the following codes, regarding its
membership in the VLAN:
–
T — Tagged. The interface is a member of a VLAN. All packets
forwarded by the interface are tagged. The packets contain VLAN
information.
– U — Untagged. The interface is a member of a VLAN. Packets
forwarded by the interface are untagged.
– F — Forbidden. The interface is denied membership to a VLAN.
– Blank — The interface is not a VLAN member. Packets associated
with the interface are not forwarded.
