Configuring vlan on Cisco Catalyst 3560

The objective to create 2 vlans. Vlan 151 as the port that will connect to the netmodem and vlan 90 as the port that connects to Cisco IP Phone 7940.

Telnet into Cisco Catalyst 3560 by using putty or any telnet tool of your choice. Enter the IP address (192.168.1.25 in my case) of the switch then click on open.

Enter the administration password for Cisco Catalyst 3560 (assuming that the switch has already been configured)

Once you have the prompt for the switch type enable then hit enter.

Enter the password for IOS to enter the configuration mode.

From this point you may enter the IOS commands below for the configuration.

To return an interface to its default configuration, use the default interface interface-id interface configuration command.
This example shows how to configure a port as an access port in VLAN 2:
Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# interface gigabitethernet0/1

Switch(config-if)# switchport mode access

Switch(config-if)# switchport access vlan 2


Switch(config-if)# end
