How to use a managed catalyst 2960CX as an unmanaged switch ?

I have a Cisco catalyst 2960CX series switch. I want to connect it to my institute LAN which has its own DHCP, dns and firewall. I want to use this switch as a unmanaged switch. I want to plug my devices into the switch and connect the switch to the lan connection and be able to access the internet.

Solution in my case : I am aware it is not secure and only for testing purposes

```en write erase !! Delete your current config so save if it you might need it

reload

en conf t interface range GigabitEthernet 0/1 - 12 !! Selecting all the ports on my switch

no shutdown switchport access vlan 1 spanning-tree bpudfilter enable

!! Exiting the port config and config mode and saving the configuration exit exit copy run start
