7.6 Protocol

7.6.1 VLAN

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, which

would allow you to isolate network traffic, so only the members of the VLAN will receive

traffic from the same members of VLAN. Basically, creating a VLAN from a switch is logically

equivalent of reconnecting a group of network devices to another Layer 2 switch. However,

all the network devices are still plugged into the same switch physically.

7.6.1.1 VLAN Mode Configuration

The switch supports port-based and 802.1Q (tagged-based) VLAN. The default

configuration of VLAN operation mode is “

802.1Q

”.
