Observations from yesterday's lab:

1. Make sure all configs are erased from the device before you start!! If you suspect there are configs left on the device: 1. Erase the configs. 2. See me for help.

2. Follow all the directions. If you get stuck, figure it out!! Don't just check it off. Checking it off won't get you the points.

3. Take good notes in your spiral-bound notebook. Take your notes home and practice building networks in Packet Tracer. If this is something you are unwilling to do you will never master the skills.

4. We only had a few students who were able to complete this simple lab without error. This was suppose to be practice! We've already covered nost of this material in the past module. You should've already learned how to connect physical cabling, configure a switch and a host in the last module.

Activity: Erase configs and put away cables.
