Connecting the Console Cable: First, I connected the console cable between the computer and the switch. Then, I usec the Device Manager to find the correct USB Serial Port. In this case, the COM port was identified as COM4.

Configuring PuTTY for Serial Communication: I opened PuTTY and configured the serial communication settings. Follow these steps:

Navigate to Connection > Serial in the left-hand menu. Set the Serial Line to the COM port number Set the following parameters: Bits per second: 9600 Data bits: 8 Parity: None Stop bits: 1 Flow control: None

Establishing the Serial Connection: After I configured the settings, I returned to the Session category in PuTTY. Then I selected the Serial option, and made sure the Serial Line is set to COM4 to establish a serial connection with the switch, giving me access to the switch’s CLI.

To configure the interface as an access port and assign it to a VLAN, I followed these steps:

enable configure terminal

interface <interface_id>

switchport mode access

switchport access vlan 100

enable configure terminal

interface vlan <vlan_number>

ip address <ip_address> <subnet_mask>

interface vlan 10

ip address 192.168.1.1 255.255.255.0

configure terminal

hostname <new_hostname>

switchport trunk encapsulation dot1q

switchport mode trunk

no shutdown

configure terminal

ip route 192.168.11.0 255.255.255.0 198.162.11.0
