Multi-layer switches are used to implement communication between different VLANs.

Multi-layer switches are used to implement communication between different VLANs.

The lab image is included in the attachment.

Basic Configuration

PC1 IP: 192.168.1.1 subnet mask: 255.255.255.0 Gateway: 16.01.254

PC2 IP: 192.168.2.1 subnet mask: 255.255.255.0 Gateway: 16.02.254

PC3 IP: 192.168.3.1 subnet mask: 255.255.255.0 Gateway: 16.03.254

A layer-2 switch SW1 and layer-3 Switch SW2 are also required.

The port of PC1 is connected to port f0/2 of the SW1 switch, and port f0/3 of the SW1 switch,

PC3 port is connected to switch SW1 port f0/4, and switch SW1 port f0/1 and layer-3 Switch f0/1

Connected.

Then configure the command for the device

Configure switch SW1

Switch> enable // Switch Mode

Switch # configureterminal

Enterconfigurationcommands, oneperline. EndwithCNTL/Z.

Switch (config) # hostnameSW1 // modify the Host Name

SW1 (config) # vlan10 // create a VLAN

SW1 (config-vlan) # vlan20

SW1 (config-vlan) # vlan30

SW1 (config-vlan) # exit // exit

SW1 (config-if) # switchportmodeaccess // change the port mode to access
