Mo introduces network engineering basics using routers and switches. Learn command-line access, ip configuration, routing between sites, vlan and inter-vlan routing, stp, port security, lacp and pagp.
Download, install, and log in to Cisco Packet Tracer (latest version 8.22) for DHCP lab simulations using a free account.
Explore tcp/ip classes and ip vs tcp, and master ip addresses as hosts on local and wide networks, converting decimal to binary in ipv4’s four octets.
Explore tcp/ip classes a, b, and c, their ranges, subnet masks, and cidr notation, including class d multicast, class e reserved, and loopback 127.0.0.1 usage.
Explore class C addresses, range 192 to 223, where the first three octets form the network and the last octet is the host, using a default slash 24.
Clarify class b addressing by using the first two octets as the network and the last two as the host, with a 255.255.0.0 (slash 16) mask.
Explain class a ip addressing, showing how the first octet forms the network while the last three form hosts, using the default 255.0.0.0 (cidr /8) mask.
Explain class d and class e, with class d for multicast to specific customers and class e for research. Highlight routing protocols such as RIP, EGP, and OSPF that notify neighbors and update routing tables, and note the classful ranges 224-239 and 240-254.
Learn how tcp and udp differ and how port numbers form source and destination sockets with well-known and private ranges.
Explain the difference between tcp and udp, use netstat to view open ports on windows server, and identify key ports such as 3389, 445, and Kerberos ports 88 and 464.
Learn how to change the remote desktop port by editing the registry, switching from 3389 to 5555, restarting, and securing access with Windows Defender firewall inbound rules.
Explore the purpose of routers and switches, how they connect LANs and WANs, and how a multilayer switch can function as both a router and a switch.
Explore UTP unshielded twisted pair cables, including straight through, crossover, and rollover (console) cables, for device connections and initial router configuration, with pinouts and tools like putty.
Explain the difference between collision domains and broadcast domains using hubs, switches, and routers, showing how switches isolate collisions and routers stop broadcasts. Routers break both collision and broadcast domains.
Explore the Cisco router command line interface, switching from user mode to privileged and global configuration mode, then configuring interfaces, subinterfaces, and line modes with help and show commands.
Discover the difference between enable password and enable secret and how to set them up in global configuration mode to switch from user mode to privilege mode on a router.
Change a router's hostname and set the time zone and clock using commands in privileged and global configuration modes. Verify changes with show clock.
View command history in privileged mode with show history and tab completion. Increase the default history size from 10 to 50 (up to 256) to reference more commands.
Understand how a Cisco router uses ram for the running config, nvram for the startup config, and flash for the eos image, plus saving and erasing settings.
Configure a router interface by enabling it, assigning a static IP 192.168.10.254/24 with a description for the internal LAN, and verify status with show ip interface brief and duplex/speed.
Configure a dedicated ntp time server on the network, assign an ip and gateway, enable ntp on port 123, configure dns to resolve time server names, and monitor stratum levels.
Configure a domain name and a dns server on the router, and enable no ip domain lookup to prevent unnecessary name resolution during cli work.
Learn to access a router via the console port using a rollover cable and Putty, compare with ssh, and configure console password, enable secret, and login timeout for secure access.
Configure remote access by assigning an IP address on the interface and enabling Telnet or SSH with an enable secret. Learn DHCP setup and VTY line limits and timeouts.
Configure usernames on Cisco routers for both console and telnet access by creating local accounts, assigning passwords and privilege levels, and enabling login local on line con and vty lines.
Learn to encrypt passwords on devices by enabling service password encryption in global configuration, save changes, and understand why disabling Telnet in favor of SSH improves security.
Configure ssh on a router, disable telnet, and enforce ssh only by setting a domain name, hostname, rsa keys, and a dedicated ssh user with local login.
Configure a banner message of the day on a Cisco router, set up dhcp, user accounts, console and vty login local, and verify access with a telnet test to router.
Learn switch configuration essentials, including setting hostname and enable secret, configuring date and time, disabling ip domain lookup, adjusting command history, and saving a running configuration.
Master switch port configuration by adding descriptions, setting speed and duplex, and administratively shutting unused ports with range commands, then verify with IP interface brief and show commands.
Explore how switches build and use the mac address table to forward frames per port, eliminating collisions and replacing hubs with smarter, dynamically learned hardware addresses.
Explore switch storage concepts, including RAM, nvram, and flash. Learn how run and startup configs differ and how to save them with copy run start.
Configure a switch via console connection with a rollover cable and PuTTY, set hostname switch1, enable secret, login on the console line, enable service password encryption, and save the configuration.
Configure the switch for telnet by enabling vty 0–2, assigning a vlan ip, securing logins with a password and enable secret, and note telnet is insecure.
Configure usernames on the switch for console and telnet access using admin one and admin two, with login local and encrypted secrets; prepare for ssh in the next lecture.
Configure ssh on a switch by setting hostname and ip domain name, generating rsa keys with sha256, creating users, enabling ssh version two, and restricting vty to ssh.
Configure a banner on the switch using global configuration mode and the banner command for a warning and welcome message. Save the configuration and anticipate centralized authentication in next lecture.
