Step 1: Configure PC Of IP Address.
Step 2: PC1 Upper Ping All other hosts are accessible.
Step 3: Set Switch1 And Switch2 Of Fa0/12 The direct connection interface

SW1 (config) # inte fa0/12 SW1 (config-If )#Switchport trunk encapsulation dot1q SW1 (config-If )#Switchport mode trunk SW1 (config-If) # exit Sw2 (config) # inte fa0/12 Sw2 (config-If) # switchport trunk encapsulation dot1q Sw2 (config-If) # switchport mode trunk Sw2 (config-If) # exit

Step 4: UseShow interface trunkOrShow interface fa0/12 switchportCommand to view and confirm
