3 Logging in the Device
The default IP address of the switch is 192.168.1.110. You can only log in the device by Console port
for first time login. The user name and the password are both “admin”, and the baud rate of the serial
port is 115200. You can view the actual IP address through show ip interface command line.
Login by console port is the most basic way to log in the local interface, and it is also the method to
configure other ways to log in the device. You can see the command line manual for details.
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 use 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).
