In 802.1q mode the untagged packets (packets with no VLAN tag) that arrive
in a port, will be tagged with the default VLAN identifier that is configured for
each port.
Figure 9-42: Switch VLAN
VLAN Mode Select one of the following Switch modes:
Transparent In transparent mode the switch is transparent to all VLANs.
802.1q In 802.1Q mode each of the Ethernet Switch ports can be
member of one or several VLANs. The switch can have up to 15 IVLs (Inde-
pendent VLAN Learning databases) or up to 64 SVLs (Shared VLAN Learning
Databases). Each VLAN has a VLAN Identifier (VID) between 1 and 4094. Up-
on reception of an Ethernet packet at a port its VID is checked against the VIDs
of all VLANs this port is a member of. Packets that do not carry one of these
VIDs will be discarded. For untagged packets the default VID for the port is
used to determine VLAN membership. Packets are only forwarded to ports that
are a member of the VLAN of this packet. Upon transmission the packet will be
tagged with the VLAN tag originally received. If the packet was untagged then
the default tag of the receiving port is added to the packet. The ports can also
be configured to send the packets untagged.
802.1Q Configuration – The 802.1Q configuration is only visible in 802.1q mode.
Default VLAN ID – The default VLAN identifier of each ports. Port1 to Port8 are
physical Ethernet ports, which are available at the rear of Watson device. The
Trunk port is the switch uplink port which is internally connected to the router LAN-
side.
Default VLAN Prio – The default VLAN priority of each ports.
VLAN Prio Overwrite – When selected the default VLAN priority will overwrite the
VLAN priority of the packets eggressing the switch port.
