Cisco and System Security Basics: Lesson 20 - Spanning-Tree Protocol Operation
https://ciscoiseasy.blogspot.com/2010/10/lesson-20-spanning-tree-protocol.html
Cisco and System Security Basics. Cisco Networking and Security Blog. Saturday, October 23, 2010. Lesson 20 - Spanning-Tree Protocol Operation. In my previous post I tried to stress the need for redundant connections between the switches. Multiple paths help us avoid a single point of failure in our designs. However, adding new connections inevitably create loops causing multiple problems. The last section of lesson 19. The ports participating in STP play different roles. The port does NOT forward any Et...

Cisco and System Security Basics: Lesson 17 - Inter VLAN Traffic Flow Analysis
https://ciscoiseasy.blogspot.com/2010/10/lesson-17-inter-vlan-traffic-flow.html
Cisco and System Security Basics. Cisco Networking and Security Blog. Sunday, October 3, 2010. Lesson 17 - Inter VLAN Traffic Flow Analysis. You had a chance to see how to implement simple VLAN scenario. It is relatively easy to configure VLANs, but what is far more important, is to understand the traffic flow between them. This post is going to show you step-by-step, how traffic flows between VLAN 10 and VLAN 20 used in the previous lesson. Fancy a little, virtual journey between VLANs? Checks the desti...

Lesson 13 - Layer 2 Connectivity Troubleshooting Part 3 | Learning Cisco for a brighter future
http://cisco4everyone.blogspot.com/2013/03/lesson-13-layer-2-connectivity.html
Learning Cisco for a brighter future. Mar 11, 2013. Lesson 13 - Layer 2 Connectivity Troubleshooting Part 3. This lesson is the last one in the series on how to troubleshoot connectivity issues at the layer 2 of OSI model. Bear in mind, that these do not involve layer 2 technologies such as VLANs or Spanning-Tree Protocol, since we have not talked about those yet. Switches are connected via fibre optics cable and the ports show proper status (interface is up, line protocol is up). First let's try to 'div...

Lesson 19 - Spanning-Tree Protocol Overview | Learning Cisco for a brighter future
http://cisco4everyone.blogspot.com/2013/03/lesson-19-spanning-tree-protocol.html
Learning Cisco for a brighter future. Mar 11, 2013. Lesson 19 - Spanning-Tree Protocol Overview. Vlans described in the previous posts are very important elements of building modern networks. Equally important piece of technology is IEEE 802.1D, commonly known as Spanning-Tree Protocol. In the following few posts, I will focus on its application and basic operation. Consider the following layer 2 design. Imagine that the SW1. Pic 1 - Switch Topology Without Redundancy. Icons designed by: Andrzej Szoblik -.

Lesson 8 - Ethernet and Hub Operations | Learning Cisco for a brighter future
http://cisco4everyone.blogspot.com/2013/03/lesson-8-ethernet-and-hub-operations.html
Learning Cisco for a brighter future. Mar 11, 2013. Lesson 8 - Ethernet and Hub Operations. After my last conversation with my son about. Building the home network I promised I'd explain to him how a hub worked. And now, he's showing at the door. . So, like in the previous lessons I'll focus on the most important aspects regarding CCNA level. Other computers will ALL receive this signal. And have to wait for their turn if they have something they want to transmit (Pic 1). Http:/ www.newo.pl. The wire to ...

Lesson 16 - VLANs In Practice | Learning Cisco for a brighter future
http://cisco4everyone.blogspot.com/2013/03/lesson-16-vlans-in-practice.html
Learning Cisco for a brighter future. Mar 11, 2013. Lesson 16 - VLANs In Practice. Lesson 15 introduced another layer 2 concept called VLANs (Virtual Local Area Networks). If you understand their purpose, it is time to get the juices flow by configuring them. In this post, I am going to show you how to configure VLANs in a simple design, routing between VLANs and how to verify their operation. I am going to use the following network topology to accomplish our goals (Pic. 1). Pic 1 - VLAN Topology. For no...

Cisco and System Security Basics. Cisco Networking and Security Blog. Monday, August 9, 2010. Lesson 3 - Initial Configuration of Cisco Switch and Router. Understanding technologies requires a skill. Even though not mine, but the best definition of what a skill is, could be summarized in five words: knowledge and one thousand repetitions. Take a look at our simple topology first:. Switch/router/computer icons designed by: Andrzej Szoblik -. Http:/ www.newo.pl. Configure the console port 0 such, that syst...
