• Selected Secondary VLANs—For promiscuous ports, move all secondary VLANs that
are required for normal packet forwarding from the Available Secondary VLANs.
Promiscuous and trunk ports can be members in multiple VLANs.
Click Apply. The parameters are written to the Running Configuration file.
Port to VLAN
The Port to Vlan and Port VLAN Membership
ports in various presentations. You can use them to add or remove memberships to or from the
VLANs.
When a port is forbidden default VLAN membership, that port is not allowed membership in
any other VLAN. An internal VID of 4095 is assigned to the port.
To forward the packets properly, intermediate VLAN-aware devices that carry VLAN traffic
along the path between end nodes must either be manually configured or must dynamically
learn the VLANs and their port memberships from Generic VLAN Registration Protocol
(GVRP).
Untagged port membership between two VLAN-aware devices with no intervening VLAN-
aware devices, must be to the same VLAN. In other words, the PVID on the ports between the
two devices must be the same if the ports are to send and receive untagged packets to and from
the VLAN. Otherwise, traffic might leak from one VLAN to another.
Frames that are VLAN-tagged can pass through other network devices that are VLAN-aware
or VLAN-unaware. If a destination end node is VLAN-unaware, but is to receive traffic from
a VLAN, then the last VLAN-aware device (if there is one), must send frames of the
destination VLAN to the end node untagged.
Use the Port to VLAN page to display and configure the ports within a specific VLAN.
To map ports or LAGs to a VLAN:
Click VLAN Management > Port to VLAN.
Select a VLAN and the interface type (Port or LAG), and click Go to display or to change the
port characteristic with respect to the VLAN.
