z 

Do not set the voice VLAN as the default VLAN of a port in automatic voice VLAN assignment 

mode. For information about voice VLAN, refer to 

z 

You are recommended to set the same default VLAN ID for the local and remote ports.  

z 

Ensure that a port is assigned to its default VLAN. Otherwise, when the port receives frames 

tagged with the default VLAN ID or untagged frames (including protocol packets such as STP 

BPDUs), the port filters out these frames.  

 

Ports of different link types handle frames as follows:  

Access 

Tag the frame with the 
default VLAN tag. 

z 

Receive the frame if its 
VLAN ID is the same as 
the default VLAN ID. 

z 

Drop the frame if its 
VLAN ID is different 
from the default VLAN 
ID.  

Remove the default VLAN 
tag and send the frame. 

Trunk 

z 

Remove the tag and send 
the frame if the frame 
carries the default VLAN 
tag and the port belongs 
to the default VLAN. 

z 

Send the frame without 
removing the tag if its 
VLAN is carried on the 
port but is different from 
the default one.  

Hybrid 

Check whether the 
default VLAN is 
permitted on the port: 

z 

If yes, tag the frame 
with the default 
VLAN tag. 

z 

If not, drop the 
frame. 

z 

Receive the frame if its 
VLAN is carried on the 
port. 

z 

Drop the frame if its 
VLAN is not carried on 
the port. 

Send the frame if its VLAN is 
carried on the port. The 
frame is sent with the VLAN 
tag removed or intact 
depending on your 
configuration with the port 
hybrid vlan command. This 
is true of the default VLAN. 

 

You can assign an access port to a VLAN in VLAN view, interface view (including Ethernet interface 

view, Layer 2 aggregate interface view), or port group view. 

1)  In VLAN view 

Follow these steps to assign one or multiple access ports to a VLAN in VLAN view:
