* VLAN mode
The smart switch supports two VLAN modes, tag based and port based. Only
one VLAN mode can be enabled at one time.
When the tag based VLAN is selected, the administrator can define the
handling method of a VLAN tag to the specified port,
including “Add Tag”,
“don’t care” or “Remove Tag”. Add tag/Don’t Care/Remove tag definitions are
as follows.
“Add Tag” means the outgoing packet should contain a 802.1Q tag.
The 802.1Q tag will be inserted to the outgoing packet of the
selected port if the packet received at the source port does not
contain 802.1Q tag.
The original 802.1Q tag will be kept if the source port received a
packet with 802.1Q tag.
“Don’t care” means the outgoing packet of the selected port keep the original
packet format of the source port.
“Remove Tag” means the outgoing packet should not contain a 802.1Q tag.
The 802.1Q tag of the outgoing packet of the selected port will be
removed if the incoming packet received at the source packet
contains 802.1Q tag.
The packet format of the source port will be kept if the packet does
not contain the 802.1Q tag.
Note: In tag based VLAN mode, adding tag on the port which is used to
configure this switch is not allowed, because some NICs cannot recognize
802.1Q tag.
Example:
Port 1: The 802.1Q tag of every packet outgoing from this port will be
removed.
Port 4: The 802.1Q tag of every packet outgoing from this port should be
included.
Other ports: keep every outgoing packet intact.
