VLAN
This chapter shows you how to set up Virtual LANs on the switch.
9.1Introduction
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only members of the VLAN group receive traffic from the same VLAN group members. Members on a different VLAN group cannot communicate with each other even though they are physically connected to the same switch.
Your switch supports
By default, all ports belong to a default VLAN (VLAN ID 1). You
cannot delete the default VLAN.
9.2VLAN Types
The following sections discussed the types of VLANs your switch supports.
9.2.1 Port-Based VLAN
By default, all the ports on the switch belong to a VLAN group (VID 1). You cannot delete the default VLAN.
9.2.2 Tag-Based VLANs (IEEE 802.1Q VLAN)
The following lists the advantages of IEEE 802.1Q.
1.Multicast data traffic across different Ethernet devices is contained, thus improving performance.
2.A port can belong to more than one IEEE 802.1Q VLAN.
3.Improved security with logical grouping of users.
