Basic Configuration Steps

Setting Hostname and Domain Name

Enter Global Configuration Mode:
plaintext
Copy code
Switch> enable

Switch# configure terminal

Set Hostname:
plaintext
Copy code
Switch(config)# hostname MySwitch

MySwitch(config)#

Set Domain Name:
plaintext
Copy code
MySwitch(config)# ip domain-name mydomain.com

MySwitch(config)#

Configuring Management Interface

Assign an IP Address to the Management VLAN (typically VLAN 1):
plaintext
Copy code
MySwitch(config)# interface vlan 1

MySwitch(config-if)# ip address 192.168.1.10 255.255.255.0

MySwitch(config-if)# no shutdown

MySwitch(config-if)# exit

Set Default Gateway:
plaintext
Copy code
MySwitch(config)# ip default-gateway 192.168.1.1

Setting Up VLANs

Create a New VLAN:
plaintext
Copy code
MySwitch(config)# vlan 10

MySwitch(config-vlan)# name Sales

MySwitch(config-vlan)# exit

Assign Ports to the VLAN:
plaintext
Copy code
MySwitch(config)# interface range gigabitEthernet 1/0/1 - 1/0/24

MySwitch(config-if-range)# switchport mode access

MySwitch(config-if-range)# switchport access vlan 10

MySwitch(config-if-range)# exit

Configuring Uplink Ports

Configure Uplink Ports as Trunks:
plaintext
Copy code
MySwitch(config)# interface range gigabitEthernet 1/0/25 - 1/0/28

MySwitch(config-if-range)# switchport mode trunk

MySwitch(config-if-range)# switchport trunk allowed vlan all
