Explore the OSI model, a conceptual, vendor-independent ISO framework that standardizes networking through seven layers and details data flow from the application layer to the physical layer, including PDU formats.
explains the application layer as the top OSI layer that provides user interfaces and data transfer, covering http/https, ftp, dns, smtp, imap, pop, snmp, telnet, dhcp, and ssl encryption.
The presentation layer is the second topmost layer of the osi model, translating, compressing, and encrypting data to ensure readability across applications and networks.
Explore the session layer of the OSI model, covering session initiation, monitoring, termination, synchronization, and dialogue control; include authentication, authorization, and accounting within simplex, half-duplex, and full-duplex transfers.
Explains the transport layer as the fourth OSI layer handling end-to-end delivery, segmentation, reliability, flow control, and multiplexing, and contrasts TCP and UDP, including three-way handshake and reliability differences.
Explore the network layer of the OSI model, covering IP and MAC addressing, routing and best path selection and forwarding, fragmentation, and ICMP error handling.
The data link layer enables node-to-node data transfer with framing, MAC addressing, CRC-based error detection, and flow and access control, with LLC and MAC sublayers handling multiplexing, sequencing, and addressing.
Learn what an IP address is and how IPv4 uses 32-bit dot-decimal notation to identify devices, classful ranges, subnet masks, private ranges, and NAT.
Master class C subnetting to reduce wasted addresses and improve traffic, performance, and management, using the default 255.255.255.0 and masks like 255.255.255.192 or 255.255.255.224 to define valid host ranges.
Learn class B subnetting by calculating host bits to meet 500 and 60 addresses, using /23 255.255.254.0 and /26 255.255.255.192 on the 172.16.0.0 and 172.17.0.0 networks.
Explore fixed length subnet mask by allocating equal IP blocks on a class c network 192.168.0.0 with /26, unveiling address wastage and introducing variable length subnet mask.
Apply variable length subnet masking to allocate 192.168.0.0 across ground, first, second, and third floors using /26, /27, /28, and /30 subnets, calculating host bits and block sizes.
Explore IPv6 addressing, including 128-bit hex blocks and address shortening; learn the EU 64 method to insert Mac addresses and global, private, link-local, multicast, and anycast addresses.
Explore how a hub broadcasts to all devices, how a bridge learns mac addresses, and how a multiport switch uses a mac address table and aging to forward frames efficiently.
Explore how ICMP ping packets flow through a switch, with ARP resolving the destination MAC address, broadcast behavior, and the role of MAC address tables in layer 2 connectivity.
Download and install Cisco Packet Tracer by logging in via Google, selecting version 8.2.2, and completing the setup to access routers, switches, access points, computers, and servers.
Explore how virtual local area networks (VLANs) logically segment a switch into isolated broadcast domains, improving security, performance, and network management by grouping interfaces for HR and sales departments.
Configure a trunk link to forward Vlan 2 and Vlan 3 traffic between switches through a single channel, enabling inter-switch Vlan communication.
Explore how dynamic trunking protocol (DTP) automates creating trunk links between Cisco switches, explaining administrative vs operational modes, negotiation, and VLAN encapsulation with dot1q.
Explore how vlan trunking protocol (vtp) centralizes vlan management across switches, automatically propagating vlan creation, deletion, and renaming through server, transparent, and client modes.
Explore how the spanning tree protocol prevents Ethernet loops by electing a root bridge and blocking redundant paths to curb broadcast storms.
Explore how spanning tree protocol prevents loops by electing a root bridge as the central reference point using bridge ID, priority, and MAC addresses, with BPDU exchanges.
Explore spanning tree protocol port states: blocking, listening, learning, forwarding, and disabled; and how bpdu exchange and mac learning determine root and designated ports.
Explore spanning tree protocol convergence time, comparing direct and indirect links, and detail 15-second listening, 15-second learning, and the blocking-to-forwarding timing.
PortFast speeds up switch port activation by skipping listening and learning on non trunking links, avoiding the 32-second boot and enabling immediate forwarding.
Configure portfast on fa0/1 to reduce the 30s spanning tree boot delay on a real switch, using global configuration and the spanning tree portfast command on a non trunking link.
Configure rapid pvst to achieve zero-time convergence and rapid loop prevention in a closed network, using root port, designated port, alternate port, and backup port.
Explore how Cisco's ether channel aggregates multiple ethernet links into a single port channel. See how static and dynamic configurations, including LACP and PAGP, boost bandwidth, redundancy, and load balancing.
Recover a forgotten switch password by connecting a console cable, using putty to access the serial port, and entering roman mode to reset and restore configuration.
Configure port security on switches to restrict mac addresses on access ports, using static or dynamic learning, and enforce violation modes such as shutdown, restrict, or protect.
Learn how DHCP automatically assigns IP addresses, subnet masks, gateways, and other parameters from a centralized server, and configures a pool with exclusions using the DORA process and DNS.
Configure a dhcp server to automatically assign ip addresses, subnet mask, gateway, and dns server 8.8.8.8 to devices on the 192.168.1.0 network, starting from 192.168.1.2 for 255 addresses.
Explore how dhcp snooping prevents rogue dhcp servers by labeling trusted versus untrusted ports, configuring vlan 1, and ensuring devices receive ip addresses from the legitimate server.
