css
Copy code
hostname [YourSwitchName]

Configure Management Interface: Assign an IP address to the management VLAN (usually VLAN 1) using the command:
css
Copy code
interface vlan 1

ip address [YourIPAddress] [SubnetMask]

no shutdown

Set Default Gateway: Configure the default gateway for external communication:
scss
Copy code
ip default-gateway [GatewayIPAddress]
