Experimental Purpose:
1. Observe the STP status of the two switches.
2. Configure the EtherChannel, and add the physical port to the channel.
3. Then check the STP status of the two switches.
4, the test is effective, a network cable off.
Experimental steps:
1. Observe the STP status of the two switches.

4, the test is effective, a network cable off.
The result: The two machines did not lose packets when they ping each other, but the delay increased a bit.
