Basic Cisco Device Commands
Objectives
1.
Secure a Cisco device using passwords.
2. Enable remote access with Telnet and SSH.
3. Create users with different privilege levels.
4.
Use custom privilege levels to limit user commands.
5. Learn how to reboot a Cisco device.
Part 1: Introduction to Basic Cisco Commands
Cisco devices allow network administrators to control access and security using the Command-Line
Interface (CLI).
•
Console Password Protection: Secures physical device access.
Telnet & SSH: Enable remote login.
• User Management: Assign different access levels to users.
•
Custom Privilege Levels: Restrict users to specific commands..
Part 2: Topology
Devices:
•
1 Cisco Router
•
1 Cisco Switch
1 PC (for configuration)
Connections:
•
•
Connect the PC to the router using a console cable.
Connect the router to the switch using a straight-through cable.

that I understand what is
happening
ip ssh version 2
4.
Create a user for SSH access:
username admin privilege 15 password admin123
5. Apply SSH to the VTY lines:
line vty 0 4
transport input ssh
login local
exit
6.
Test SSH from another device:
ssh -l admin 192.168.1.1
Step 4: Manage User Privileges
1. Create a user with limited privileges:
username user1 privilege 1 password userpass
2. Assign a custom privilege level (example: level 5):
username guest privilege 5 password guestpass
3. Restrict the user to only three commands:
privilege exec level 5 show ip interface brief
privilege exec level 5 show clock
privilege exec level 5 show version
4. Apply the privilege level to VTY users:
line vty 04
privilege level 5
Step 5: Reboot the Device
1. Save the configuration before rebooting:
Explain to me in a practical way so
that I understand what is
happening
2. Plot the expected output voltage waveforms for the given circuits.
Assuming V=5v and VON 0.7v for each diode.
