Displays the membership type for each VLAN. The possible field values are:

 

 

 

z Untagged: Indicates the interface is an untagged member of the VLAN.

 

 

 

z Tagged: Indicates the interface is a tagged member of a VLAN. VLAN

 

 

 

tagged frames are forwarded by the interface. The frames contain VLAN

 

 

 

information.

 

 

 

z Not A Member: Indicates the interface is not a member of the VLAN

 

 

 

Each port on the switch is capable of passing tagged or untagged frames.

 

 

 

The following describes how the switch will handle tagged and untagged

 

 

 

frames.

 

Membership type

 

z When a port receives a tagged frame with a VLAN ID and the port is a

 

 

member (untagged or tagged) of that VLAN, the frame is accepted.

 

 

 

Otherwise if the port is not a member of that VLAN, the frame is

 

 

 

discarded.

 

 

 

z When a port receives an untagged frame and the port is an untagged

 

 

 

member of a VLAN, the frame is accepted and assigned to that VLAN ID.

 

 

 

Otherwise if the port is not an untagged member of any VLAN, the frame

 

 

 

is discarded.

 

 

 

The switch will only forward a frame to ports that are members (tagged or

 

 

 

untagged) of the VLAN to which the frame is assigned. If the port is an

 

 

 

untagged member, the egress frame will be stripped of the VLAN tag and

 

 

 

forwarded as untagged. However, if the port is a tagged member, the egress

 

 

 

frame is forwarded as tagged.
