Yêu cầu:
Gợi ý:
2a: Dùng lệnh sau trên switch trong mode interface:
Switch(config-if)# switchport trunk encapsulation dot1q
Switch(config-if)# switchport mode trunk
!Lưu ý: phải gõ lệnh “switchport trunk encapsulation dot1q” trước lệnh “switchport mode trunk”, nếu gõ theo thứ tự ngược lại sẽ không thể tạo kết nối trung kế thành công
2b: Dùng lệnh sau trên router để cấu hình trung kế dot1q:
Router(config)# interface fastethernet 0/0.11
Router(config-if)# encapsulation dot1q 10
Router(config-if)# ip address 192.168.1.1 255.255.255.0
!lưu ý: câu lệnh trên tạo subinterface f0/0.11, chỉ định encapsulation là dot1q, thuộc VLAN 10 và có IP 192.168.1.1.
3: Dùng lệnh sau để cấu hình VTP:
Switch(config)# vtp domain BCMSN
Switch(config)# vtp mode { client | server | transparent }
Switch(config)# vtp password CISCO
4: Dùng các lệnh sau để cấu hình VLAN:
Switch(config)# vlan 10
Switch(config-vlan)# name VLAN10 !ßđặt tên là VLAN10
Switch(config)# interface range fastethernet 0/1 – 6
Switch(config-if-range)# switchport mode access
Switch(config-if-range)# switchport access vlan 10
