4.2.3.2
VLAN Mode
VLAN Mode: Port based
Packets can go among only members of the same VLAN group. Note all unselected ports are treated as belonging to another single
VLAN. If the port‐based VLAN enabled, the VLAN‐tagging is ignored.
show vlan mode
Display the current VLAN mode.
vlan mode (disabled|port‐based|dot1q)
Change VLAN mode.
Parameters:
(disabled|port‐based|dot1q) specifies the VLAN mode.
NOTE: Change the VLAN mode for every time, user have to restart the switch for valid value.
VLAN Mode: 802.1Q
If a trunk group exists, you can see it (e.g. TRUNK1, TRUNK2...) after port 24. And, you can configure it to be a member of the VLAN
group.
In the setting, port was set to Untagged if devices underneath this port do not support VLAN‐tagging. Thus the switch can send
untagged frames to this port. Consequently, device that do not support VLAN‐tagging or do not enable VLAN tagging could
successfully fetch the incoming frames and could communicate with device that transfers tagged frames, and vice versa. In the
following figure, two different types of devices want to communicate with each other. Since computer A support 802.1Q VLAN and
computer B do not, you have to configure two ports both beneath the same VLAN group, and set left port to "Tagged", right port to
"Untagged". Therefore, two devices will receive packet type as they desired.
