Planet WSW-2401A [45/95] Vlan configuration

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 Trunk 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 Configuration

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.

2. The main page then change to Port-base VLAN table, click on the “Add/Modify” button to create a new VLAN

group.
