Packet Tracer Cisco Packet Tracer is a powerful network simulation program that allows students to experiment with network behavior and ask “what if” questions. As an integral part of the Networking Academy comprehensive learning experience, Packet Tracer provides simulation, visualization, authoring, assessment, and collaboration capabilities and facilitates the teaching and learning of complex technology concepts. Packet Tracer supplements physical equipment in the classroom by allowing students to create a network with an almost unlimited number of devices, encouraging practice, discovery, and troubleshooting. The simulation-based learning environment helps students develop 21st century skills such as decision making, creative and critical thinking, and problem solving. Packet Tracer complements the Networking Academy curricula, allowing instructors to easily teach and demonstrate complex technical concepts and networking systems design. Download Instructions

Here is the break down: Central Web Authentication on the WLC and ISE Configuration Example Introduction This document describes a configuration example that is used in order to complete Central Web Authentication (CWA) on the Wireless LAN Controller (WLC). Prerequisites Free CCNA Workbook Free Network Diagram Software - Cisco Certification In order to pass your Cisco Certification exam, you are required to memorize countless technical details. The best way to do this is to practice your skills over and over again across many labs. Unfortunately, without a way to document your labs, a lot of what you practiced is still forgotten. NetBrain Personal Edition can help you document your labs automatically, by allowing you to: Discover devices and create rich diagrams from your configuration data Automatically capture, organize, and annotate show command results Take notes alongside the map with the built-in Notes tab Once your lab is fully documented inside a NetBrain Qmap, you can review it down the road without the hassle of having to rebuild it.

CCNA Training 3 WAN Protocols: HDLC, PPP, and Frame-Relay You Should Know » Router Switch Blog Your company is connected to the Internet, isn’t it? So what WAN protocol do you use to connect to the Internet? Chances are, that if you have a T1 leased line to the Internet or a private network between locations, you use one of these 3 WAN Protocols: HDLC, PPP, or Frame-relay. Identity Services Engine Upgrade Guide, Release 1.3 - Before You Begin [Cisco Identity Services Engine] If you encounter a problem, such as network outage or application startup failure, even after sequencing the NICs, check the downloaded version of the bundle. It is possible that you might have downloaded a previous version of the bundle that resulted in the inconsistent state of the NICs. Verify that the bundle has the following MD5 checksum: 76e17877c2fb70d1006a20780fbf5b98. If there is network outage or application startup failure following upgrade, as a result of using an older bundle, you can re-image the failed node with Cisco ISE 1.2 software, register it to the old deployment, and restore the operations backup (if the node had a Monitoring persona). Then, you can attempt to perform the upgrade using the latest bundle again.
