1. Configure e0/0/1 of SW1 to full duplex, and e0/0/1 of SW2 to half duplex.
Before the experiment:
1. The switch defaults to auto-negotiation. If you want to change the port to full-duplex or half-duplex, you need to execute the undo negotiation auto command
. 2. After auto-negotiation is turned off, the port defaults to full-duplex. Proof: After closing self-coordination, execute duplex full, and then execute dis th will find that there is no duplex full command.
