Membership type 

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. 

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.
