GNS3 Config & CISCO IOS Collections

What is GNS3?(Graphical Network Simulator)

GNS3 is an open source (GNU GPL) software that simulate complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches.

GNS3 provides an intuitive graphical user interface to design and configure virtual networks, it runs on traditional PC hardware and may be used on multiple operating systems, including Windows,Linux, and MacOS X.

In order to provide complete and accurate simulations, GNS3 actually uses the following emulators to run the very same operating systems as in real networks:

Dynamips, the well known Cisco IOS emulator. VirtualBox, runs desktop and server operating systems as well as Juniper JunOS. Qemu, a generic open source machine emulator, it runs Cisco ASA, PIX and IPS.

GNS3 is an excellent alternative or complementary tool to real labs for network engineers, administrators and people studying for certifications such as Cisco CCNACCNP and CCIE as well asJuniper JNCIA, JNCIS and JNCIE.

It can also be used to experiment features or to check configurations that need to be deployed later on real devices.

GNS3 also includes exciting features, for instance connection of your virtual network to real ones or packet captures using Wireshark. Finally, thanks to the VirtualBox support, even system administrators and engineers can take advantage of GNS3 to make labs, test network features and study for Redhat (RHCE, RHCT) and Microsoft (MSCE, MSCA) certifications to name a few

CPU usage

We talked about CPU Usage a bit earlier when we learned how to determine idlepc values. Without idlepc values configured, you may have noticed that your system’s CPU was running at 100%. This is because Dynamips, the core emulator running under GNS3, does not know when the virtual router is idle, and when it is performing useful work. The “idlepc” command performs analysis on a running image to determine the most likely points in the code that represent an idle loop in the IOS process. Once applied, Dynamips “sleeps” the virtual router occasionally when this idle loop is executed. This significantly reduces CPU consumption on the host without reducing the virtual router’s capacity to perform real work.

IdlePC values are particular to an IOS image. They will be different for different IOS versions, and even for different feature-sets of the same IOS version. However idlepc values are not particular to your host PC, operating system, or to the version of Dynamips that GNS3 is using. It is possible that Dynamips will not be able to find and idlepc value for an image, or that the values it does find do not work. If this happens, try repeating the process again.

Cisco CCNA Certification: Redesigned

Cisco CCNA Certification: Redesigned

Published March 26, 2013
By Anne Martinez

Cisco’s recent changes to its CCNA certification stop short of a complete overhaul, just barely.

Say goodbye to the base Cisco Certified Network Associate (CCNA) certification and the role it’s played as the doorway to CCNA specialty credentials. Going forward the plain vanilla CCNA will be transformed into specialty concentration: CCNA Routing & Switching; in other words, it will line up right alongside CCNA Wireless, CCNA Security, and other CCNA specializations. It will be on equal footing with them, level-wise, and no longer serve as a prerequisite.

You no longer have to earn base CCNA certification before you can step up to a specialty such as CCNA Security.

Cisco’s ICND1 exam, which leads to the Cisco Certified Entry Networking Technician (CCENT), will take over the base station role in the Cisco certification program going forward. ICND1 (a.k.a. CCENT) will also be added as a prerequisite to the current Cisco Certified Design Associate (CCDA) credential in October, making that a 2-exam certification as well.

In fact, with these changes, all of Cisco’s associate-level certifications can be earned by passing two required exams. For example, you no longer have to earn the CCNA certification before you can earn the CCNA Security certification. The new structure works like this:

CCNA Certifications Requiring CCENT

Certification Requirements
CCNA Routing and Switching CCENT + ICND2
CCDA CCENT (starting Oct 1) + DESGN

Most of Cisco’s associate-level credentials now start with the CCENT, but not all.Some of the newer CCNA specializations already follow the 2-exam model, and the required exams for those haven’t changed, even though they don’t start with ICND1.

CCNA Certifications Not Requiring CCENT

Certification Requirements

According to Cisco, these changes are intended to meet predicted employer needs for specialists in key areas and go far beyond rearranging which exams lead to which credentials. Cisco has completely updated the training curricula and created corresponding new versions of the ICND1 (CCENT), ICND2, and the CCNA Composite exams. The updates include comprehensive troubleshooting, technologies such as IPV6, and updated software on Cisco routers and switches. The new exams and training are available as of March 26, 2013.

If you’re already the proud owner of a base CCNA credential, you may notice it’s been renamed to CCNA R&S in Cisco’s database. There won’t be any other changes for current CCNA credential holders.

See GoCertify’s Cisco Certification list for more info on Cisco’s many certification options.
