From my observation, i found that there are some student did not understand the Cisco CLI command hierarchy. Means that you don't understand the flow of Cisco IOS command.
Please understand this hierarchy and i will randomly pick any student and present it in the class.
Please read the full explanation of Cisco IOS Command hoerarchy from this site: http://www.cisco.com/warp/cpropub/45/tutorial.htm
p/s:Please put it on your lecture note + Copy the Cisco Command Summary from this site: http://networking.ringofsaturn.com/Cisco/ciscocommandguide.php
To assist users in navigation through IOS CLI, the command prompt will change to reflect the position of a user within the command hierarchy. This allows users to easily identify where within the command structure they are at any given moment. Table 2 is a summary of command prompts and the corresponding location within the command structure.
Table 2 - IOS Command Prompt Summary
