Interface GigabitEthernet0/1

Switchport access vlan 2

Switchport mode access

// Switchport host (host mode) = switchport mode access + switchport portfast (TRUNK port not supported)

Switchport protected // Port Protection, which prevents mutual access between hosts

Storm-control broadcast level 0.01 // broadcast storm control

Spanning-tree portfast // port Quick Start; otherwise, it takes about 50 seconds to wait for the spanning tree to converge.

Spanning-tree bpduguard enable // when a loop exists, the port changes to the err-disable State and must be manually disabled before enabling

Ip dhcp snooping // enable DHCP detection globally

Interface GigabitEthernet0/24

Switchport trunk encapsulation dot1q

Switchport mode trunk

Ip access-group 110 in // application to entry direction

Ip dhcp snooping trust // trust, that is, only accept the DHCP service under the TRUNK Port

Access-list 110 deny tcp any eq 3389 // Disable Remote Desktop
