Emphasize: Use this slide for your first introduction of Cisco IOS software to your students. Cisco IOS software is the platform that delivers network services for the network applications. This IOS software platform extends beyond the routers. IOS applies as well to selected Catalyst switches. Eventually, all Cisco platforms may merge to the Cisco IOS software. Note: The Cat 1900 and 2900xl switch IOS has a common look and feel like the router’s IOS. However, the switch IOS is not 100% identical to the router’s IOS. Slide 1 of 1 Purpose: This slide introduce the two IOS EXEC modes on the Cat1900 switch and routers. Emphasize: As you present this, describe the bullet points that can prepare your students to work with the Cisco IOS user interface. Slide 1 of 1 Purpose: This slide describe the Priviledged EXEC mode. Emphasize: As you present the introductory material on Privileged (also called “enabled”) mode, emphasize that this mode is the entry mode for all the other configuration modes. Tell your students that they will need this mode for ICND labs and most of the network administration that they do back on the job. Use the analogy of “the price of admission”: You must type enable and then pay with the correct enable password; otherwise, you do not get into the network device; you have to stay outside in user mode where you can only
