Assigning An Access Port To A Vlan - 3Com S7906E Configuration Manual

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
You are recommended to set the same default VLAN ID for the local and remote ports.
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:
Port type
Tag the frame with the
Access
default VLAN tag.
Trunk
Check whether the
default VLAN is
permitted on the port:

Assigning an Access Port to a 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:
To do...
Enter system view
Actions (in the inbound direction)
Untagged frame
If yes, tag the frame
with the default
VLAN tag.
If not, drop the
frame.
Use the command...
system-view
Voice VLAN Configuration.
Tagged frame
Receive the frame if its
VLAN ID is the same as
the default VLAN ID.
Drop the frame if its
VLAN ID is different
from the default VLAN
ID.
Receive the frame if its
VLAN is carried on the
port.
Drop the frame if its
VLAN is not carried on
the port.

1-6
Actions (in the outbound
direction)
Remove the default VLAN
tag and send the frame.
Remove the tag and send
the frame if the frame
carries the default VLAN
tag and the port belongs
to the default VLAN.
Send the frame without
removing the tag if its
VLAN is carried on the
port but is different from
the default one.
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.
