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. Explain to me in a practical way so that I understand what is happeningarrow_forward

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.

The applied electric field is zero. A light source is incident on the end of the semiconductor as shown in Figure P6.19. The steady-state concentration of excess carriers generated at x = 0 is 8p(0) = Sn(0) = 2 x 104 cm³. Assume the following Light p type x=0 Figure P6.19 | Figure for Problems 6.19 and 6.21. parameters: μ = 1200 cm²/V-s, μp = 400 cm²/V-s, T = 10-6 s, and 7p = 5 × 10-7 s. Neglecting surface effects, (a) determine the steady-state excess electron and hole concentrations as a function of distance into the semiconductor, and (b) calculate the steady-state electron and hole diffusion current densities as a function of distance into the semiconductor.arrow_forward*6.24 Consider the semiconductor described in Problem 6.19.
