Meet the CLI
Start the storyline by learning how to move through network device prompts and read command output.
First Contact
Take control of your first switch. Learn what its prompt means, ask it for help, and get ready to configure it.
Give It a Name
Set the switch hostname and verify it in the running configuration.
Learning From Errors
Break the CLI on purpose: trigger IOS's classic error messages, read the ^ marker, finish an incomplete command, and unlock show commands from config mode with 'do'.
Find Your Way Around
Practice moving between CLI modes without getting lost.
Type Smart, Not Hard
Abbreviations and Tab make you fast — learn where they bite before the exam does.
Read the Switch - VLANs
Use show commands to inspect VLAN membership and practice shutting down an interface.
Make and Undo
Create two VLANs, confirm them with show vlan brief, then remove them with the no command and confirm they are gone.
Read the Switch - Interfaces
Use show commands to inspect interface status and bring a port back up.
Save Your Work
Learn the difference between running and startup configuration, then save your changes.
Test 1 — Investigate
Audit a misconfigured switch, fix the hostname, create the required VLANs, bring the disabled desk port back online, and save your work.
Leave a Note
Configure a message-of-the-day banner and verify it appears in the running configuration.
Security First
Set an enable password and test logging in with it.
Lock the Door
Set an enable secret and configure the console line password.
Where is the Remote
Configure VTY lines for remote access and set a shared password.
Who Gets In
Create local user accounts and switch from shared line passwords to per-user authentication.
Test 2 — Access Review Before Go-Live
Reinforce console security, VTY access, local authentication, verification, and saving.
Exam — Configure Your First Switch
Combine everything you learned in Meet the CLI into one complete baseline configuration.
Exam — SSH Into the Switch
Turn a console-only switch into one you can administer remotely: build the full SSH stack, then prove it by opening an SSH session from the PC.
