6.1.2 VLAN ID

Each VLAN has an identification number, called VLAN ID. The range of VLAN ID ranges

from 0 to 4095, of which 0 and 4095 are not used, and the actual efficiency is only 1 to 4094 。

VLAN ID uniquely identifies a VLAN 。

The switch supports 4094 VLAN, and when you create VLAN, you choose a VLAN ID,

ranging from 2 to 4094。Switches create VLAN1 by default, and VLAN1 cannot be deleted。

There are three kinds of data frames transmitted in a VLAN network：A data frame without

tags, a data frame with VID 0, a data frame with VID 0 Non marked。As shown below, there are

three different formats of data frames。

All data frames within a switch are marked。If a marker free data frame is entered into the

switch, the switch adds a tag to the data frame, and selects a VLAN ID value to fill in the marked

VID。If a data frame with VID 0 is entered into the switch, the switch selects a VLAN ID value to

fill in the marked VID。If a data frame with VID non 0 tag is input to the switch, the frame

remains unchanged。
