Vlan Configuration - Planet WGSW-2840 User Manual

decisions are based upon this PVID, in so far as VLAN are concerned. Tagged packets are forwarded
according to the VID contained within the tag. Tagged packets are also assigned a PVID, but the PVID is
not used to make packet forwarding decisions, the VID is.
Tag-aware switches must keep a table to relate PVID within the switch to VID on the network. The switch
will compare the VID of a packet to be transmitted to the VID of the port that is to transmit the packet. If
the two VID are different the switch will drop the packet. Because of the existence of the PVID for
untagged packets and the VID for tagged packets, tag-aware and tag-unaware network devices can
coexist on the same network.
A switch port can have only one PVID, but can have as many VID as the switch has memory in its VLAN
table to store them.
Because some devices on a network may be tag-unaware, a decision must be made at each port on a
tag-aware device before packets are transmitted – should the packet to be transmitted have a tag or not?
If the transmitting port is connected to a tag-unaware device, the packet should be untagged. If the
transmitting port is connected to a tag-aware device, the packet should be tagged.
Default VLANs
The Switch initially configures one VLAN, VID = 1, called "default." The factory default setting assigns all
ports on the Switch to the "default". As new VLAN are configured in Port-based mode, their respective
member ports are removed from the "default."
VLAN and Link aggregation Groups
In order to use VLAN segmentation in conjunction with port link aggregation groups, you can first set the
port link aggregation group(s), and then you may configure VLAN settings. If you wish to change the port
link aggregation grouping with VLAN already in place, you will not need to reconfigure the VLAN settings
after changing the port link aggregation group settings. VLAN settings will automatically change in
conjunction with the change of the port link aggregation group settings

4.7.1.2 VLAN Configuration

Port-based VLAN
Packets can only be broadcast among other members of the same VLAN group. Note all unselected
ports are treated as belonging to the default system VLAN. If port-based VLAN are enabled, then
VLAN-tagging is ignored.
1. On VLAN Configuration table, choose Port-based VLAN. Click on the "OK" button.
