Cisco brings security to life with animated characters

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Cisco has appointed a select group of Cisco Engineers to develop a state-of-the-art security force. ‘The Realm.” growing beyond the systems in which they were created into a group of powerful defenders. Forming a unified league of security, the defenders battle Botnets, Malware, Spam and Intruders in the Realm, assuring the safety and security of every citizen on the human network.

‘The Realm.”is an online comic that animates the pane flow and adds voice narration. Creatively it’s an engaging experience, not as complete as a full scale animation but more alive that just a flat 2D image.

VLAN Trunking Protocol (VTP) Overview – Series 4

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

What do you think what happens? If a new Cisco Catalyst® switch is placed between any two VTP domains, the Cisco Catalyst® switch will join the VTP domain identified by the first VTP update it receives. Just check the below example.

 

 

The VTP domain can be changed to another in a Cisco Catalyst® switch by using the CLI prompt, this is the only way you can change.

Review for CCENT 640-822 Network Simulator

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

CCENT 640-822 Network Simulator is a simply great simulator for the CCNA Certification aspirers covering all the ICND1 topics.

 The  state-of-the-art, interactive simulation software enables you to practice your networking skills with 98 structured labs designed to help you learn by doing, which is the most effective method of learning.

The CCENT 640-822 Network Simulator is divided into three categories, Skill Builder, Configuration Scenario and Troubleshooting Scenario.   The best part of the CCENT 640-822 Network Simulator is its very fast consumes less CPU processing power & it’s a java based application. The lab scenarios included in the CCENT 640-822 Network Simulator are far more complex, challenging you to learn how to perform realistic network configuration and troubleshooting tasks. The CCENT 640-822 Network Simulator is best for the CCNA Certifications aspirers especially for the guys who have less exposure to real environment.

The best thing about the CCENT 640-822 Network Simulator is the organization of labs. The Skill builder consists of three parts; even the Configuration Scenario consists of three parts where as Troubleshooting scenario has one part. These labs are quite handy and useful. The moment you open any lab the corresponding pdf file opens with the lab instructions. You are supposed to answer few questions in the labs, the LAB topology is explained well.

I would strongly recommend the CCENT 640-822 Network Simulator for anyone who is depended on the self study. CCENT 640-822 Network Simulator is available only as a download, and is a subset of the CCENT 640-822 Network Simulator, covering all the ICND1 topics.

VLAN Trunking Protocol (VTP) Overview – Series 3

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

In Cisco Catalyst® switches the VTP domain can be added through CLI configuration or else it can be learnt from an adjacent VTP Cisco Catalyst® switch. Let’s see this from the below example

 

Switch C is added to the network connecting via a trunk port to Switch B with no VTP domain configured, in this mode when the Switch C receives the first VTP update from the adjacent Switch B , it will become the part of the VTP domain ITKE as identified in the VTP update.
