Virtual Local Area Network (VLAN) is frequently and widely applied. It is the basic to divide the
network. VLAN is the network that multiple devices are logically organized as one network,
regardless of the physical location of the devices. Every VLAN is a logical network with all
functions and attributes of traditional physical network. Every VLAN is a broadcast domain, and
the broadcast packet can only be forwarded within one VLAN. The broadcast packet cannot be
forwarded across different VLANs.
Port-based VLAN
Port-based VLAN is that one switch can divide the logical working groups by controlling
interoperability between two and several ports. Dividing the port VLAN reasonably can enhance
network security, improve bandwidth availability, and reduce the probability of broadcast storm.
This series of products support 4094 VLANs. When you create the VLAN, you need to select a
VLAN ID which ranges from 2 through 4094. By default, VLAN 1 is cerated, and it cannot be
deleted.
Application Example
Networking Requirement
There are two users, user 1 and user 2. They need to be in different VLANs because the
network function and environment they used are different. User 1 belongs to VLAN 2,
connected to the switch port G1/1 (GigabitEthernet 1/1). User 2 belongs to VLAN 3, connected
to switch port G1/2 (GigabitEthernet 1/2).
Configuration Procedure
To configure the switch, do the following:
Step 1
Create the VLAN.
SWITCH #configure terminal
SWITCH (config)#vlan 2
