🟑 Half Duplex vs 🟒 Full Duplex

 



Switch1(config)#int fa0/1

Switch1(config-if)#duplex full

Switch2(config)#int fa0/1

Switch2(config-if)#half duplex

🧠 Simple Explanation

🟑 Half Duplex

Like a walkie-talkie
Only one person talks at a time → collisions possible

🟒 Full Duplex

Like a telephone call
Both people talk at the same time → no collisions

πŸ” Verification Commands (Switch)

show interfaces fa0/1

You will see:

Full-duplex, 100Mb/s

or

Half-duplex, 100Mb/s

πŸ–§ VLAN (Virtual Local Area Network)

  πŸ–§ VLAN (Virtual Local Area Network) 🧠 Top 5 Key Points Logical Network Segmentation: VLANs divide a physical network into multiple logical networks , thus breaking broadcast domain. Improved Security: Devices in different VLANs cannot communicate unless explicitly allowed via a router or Layer 3 switch . Reduces Broadcast Domains: Each VLAN is its own broadcast domain , minimizing unnecessary traffic. Better Management: Departments (HR, Sales, IT, etc.) can be grouped into different VLANs without changing physical cabling . Requires VLAN Tagging (802.1Q): VLAN information is carried between switches using 802.1Q trunking . VLAN Benefits: Improved security by isolating sensitive systems  Reduced broadcast traffic and better performance Smaller broadcast domains mean less unnecessary traffic and bandwidth saved.. Easy to troubleshoot.  Trunk can carry traffic for up to 4094 VLAN IDs ( ie 4094 subinterfaces ). . Complete Flow PC1 (No Tag) | ...

🌐 NAT (Network Address Translation)

  🌐 NAT (Network Address Translation) 🧠 Top 6 Key Points Translates Private IPs to Public IPs: NAT converts internal (private) IP addresses into a single or multiple public IPs so that devices inside a LAN can access the Internet. Conserves Public IP Addresses: NAT allows multiple internal hosts to share one public IP, saving global address space. Improves Security: Internal IPs remain hidden from the outside world, reducing attack exposure. Types of NAT: Static NAT: One-to-one mapping (internal ↔ public).  ( Server) Dynamic NAT: Many-to-many mapping (pool of public IPs).  (  PAT (NAT Overload): Many-to-one mapping (most common).  Configured on Routers: NAT runs on routers at the boundary between private and public networks , translating IPs for outbound/inbound traffic. NAT Type Used Today 6 Common Use Static NAT ✅ Yes  (limited use 7 Publishing internal servers with a dedicated public IP Dynamic NAT ⚠️ Rarely L...

πŸ›°️ OSPF (Open Shortest Path First)

  πŸ›°️ OSPF (Open Shortest Path First) 🧠 Top 5 Key Points about OSPF Link-State Protocol → OSPF shares detailed information about network topology (not just hop count). Metric: Uses cost , calculated based on bandwidth (higher bandwidth = lower cost). Fast Convergence: Quickly detects and adapts to network changes. Supports VLSM & CIDR: Fully classless , allowing subnet flexibility. Area-Based Design: Supports hierarchical networks (Area 0 = Backbone, others connect to it). ⚙️ Additional Notes Works at Layer 3 (Network Layer) of the OSI model. Uses Dijkstra’s SPF (Shortest Path First) algorithm. Multicast addresses: 224.0.0.5 → All OSPF routers 224.0.0.6 → Designated Router (DR) and Backup DR OSPF uses Link-State Advertisements (LSAs) to exchange topology information. Each LSA type has a specific purpose. Here's a practical explanation of LSA Types 1–7 . 1. Type 1 – Router LSA Generated by: Every OSPF router Flooded within...
