Six Free Cisco Labs



There are test environments available free-of-charge for CCIE, CCNA and CCNP certs

By Jim Duffy
Looking for some practical experience with Cisco routers and switches for little to no cost? There's no shortage of free Cisco labs on the Web.
These sites are designed to assist network operators and Cisco certification students with common problems or challenges that crop up in configuring Cisco networks. In some instances, they may serve as teasers to get students to pay for more elaborate and comprehensive testing services.
Here's a sample of six free Cisco labs available either online or in person:
PacketLife Community Lab - Currently offline until November, the PacketLife community Lab provides free access to "modern" Cisco networking equipment for training purposes. Lab equipment and other costs are provided or sponsored by the site's owner, commercial sponsors, and voluntary contributions by community members.
Free Cisco Catalyst Switch Lab - This non-commercial effort provides free 24x7 access to Cisco Catalyst switches to learn networking, Cisco IOS, and prepare for certification exams. It requires no reservation or registration. Users telnet in to get 80-90 minutes per session on each console line, a one hour waiting period, and a two hour reset period. Users have many logins and sessions per day on each console, and can login to as many devices as they want that are available. Each line is timed separately.
Free Cisco Lab -- Free Cisco Lab is dedicated to providing educational help for students pursuing Cisco certifications. It provides exam preps, practice exams and free lab scenarios for routing, switching, security, wireless, and VOIP. It is operated by Barry Burdette, a 15-year network industry veteran who has designed, installed and maintained network infrastructure during his career.
Free Cisco Lab Simulators - The Ciscoconsole site has a link to free Cisco lab simulators available for download. One is the GNS3 simulator, an open source program that allows users to design complex network topologies. The program enables emulation of many Cisco IOS router platforms, IPS, PIX and ASA firewalls, and Juniper's Junos. It also simulates simple Ethernet, ATM and frame relay switches, and enables connection of the simulated network to production networks. GNS3 also performs packet capture using Wireshark. It can be run on multiple operating systems, including Windows, Linux, and MacOS X.
Dynamips - Dynamips is an emulator program for Cisco routers. It emulates Cisco router hardware by booting a Cisco IOS image into the emulator. Dynamips emulates Cisco 1700, 2600, 3600, 3700, and 7200 series routers for testing and experimenting with IOS features, and checking configuration before production deployment. GNS3 can be a graphical front-end for Dynamips; another front-end isDynagen.  Dynamips runs on Linux, Mac OS X or Windows.
Free CCNA Workbook - This site provides a free lab to those that prefer to use real equipment over emulated gear from Dynamips/Dynagen/GNS3. The lab consists of Cisco 3725, 3550 and 2950 hardware running 12.4 images of IOS. Each lab session is limited to total of three consecutive hours, which equates to eight sessions per day. Users are only permitted to schedule one session at any given time.

Motivational Moment

When you start giving out, you’ll soon begin taking in.

There’s an old folk song about a thirsty traveler who comes across a pump in the desert. An attached note explains that there’s a jar of water buried nearby to prime the pump. You’ve got to give before you get, the note says. It is up to the traveler to decide whether to drink the water from the jar or take a chance that the small amount of water invested will result in an unlimited supply of cold, clear water. So it is with going the extra mile. You’ve got to give before you get. You cannot expect to receive generous rewards and then decide what to give in return. You must give freely and have faith that the rewards will eventually come. As clergyman Frank Crain once said, “You may be deceived if you trust too much, but you will live in torment if you do not trust enough.

A Grand Rapids Power Analysis


A very interesting discussion on power and how it works in one of  Michigan's  economic power centers.

A Grand Rapids Power Analysis

This information was presented at an event hosted by the Bloom Collective on September 8 and is re-posted here with the help of several Bloom Collective members.
The presentation began with the premise that in order for institutional or systemic change to take place in any community, people must have a clear understanding of who has power, both economic and political power.
The first slide shared was on understanding the Hierarchy of Power, which is included here.
The hierarchy of power believes that private economic power is the strongest form of power and that this sector of power uses political power to control state power. What is meant by political power is the idea to influence state policy through money and political leverage, which is often manifested in the relationships that private power has, the amount of assets and the associations and boards that it occupies.
Once the idea of a hierarchy of power was established, there was a discussion of who represented private power in Grand Rapids. There certainly are large, global corporations that have a presence in Grand Rapids, such as JP Morgan Chase Bank, AT&T, Coca Cola, Veolia and General Motors. These companies have power in that they can demand tax breaks and subsidies for setting up shop in the area, but they rarely influence local policy on a more regular basis.
The families, individuals and associations that were identified as having the real power in this community includes (but is not limited to) the following: DeVos, Meijer, Van Andel, Cook, Seechia, Michael Jandernoa, John Kennedy, David Frey, Sam Cummings, Huntington, the GR Chamber of Commerce, The Right Place Inc., The Econ Club of Grand Rapids, the West Michigan Policy Forum, Grand Action and the Downtown Development Authority (DDA).
These are the families and entities that through individual wealth or collaboration too often dictate the outcome of policies, economic development and major cultural dynamics that impact the entire community.
The easiest example is the DeVos Family. Their collective wealth and assets is astounding. You can see here how much they own and can get a more detailed listing at this link.
In addition to the wealth & assets that the DeVos Family holds, they influence policy through direct contributions to political parties/candidates or campaigns. According to data provided by the Center for Responsible Politics, we determined that the DeVos family had collective given over half a million dollars in the 2012 election cycle by July.
Other examples of members of the DeVos family influencing policy are the recent donation of$250,000 by Richard DeVos to Wisconsin Gov. Scott Walker in his bid to defeat a recall campaign and a $500,000 donation by Doug DeVos to the National Organization for Marriage (NOM), a lead organization that fights marriage equality across the country. On a more local level, the DeVos family has given money to influence the politics of local universities and colleges, religious institutions, hospitals and non-profits.
In addition to the power that individual families have because of their vast amount of wealth, they also have power through formal associations. If one were to look at who sits on the boards of entities like the Grand Rapids Chamber of CommerceGrand Action, the Econ Club of Grand Rapids, the West Michigan Policy Forum and the Right Place Inc., one can see the wealthiest and most powerful people occupying those boards. One can also begin to see that certain names appear over and over again, thus creating what could be called interlocking systems of power. Here is a graph to illustrate these interlocking systems in Grand Rapids.
These are the organizations and associations that the wealthiest families use to dictate policy in this community. We have seen this historically with the development of downtown Grand Rapids over the past 20 years, whether it was the construction of the arena, the convention center and now the so-called “urban market.”
Understanding that private economic and political power is greater than state power, we can then see how the state more often than not operates to maintain the social stratification created by the local elites. Through police, the courts and the jail, the state will deal with disproportionately poor and minority communities by putting them in the Prison Industrial Complex. This is not to say that the state does no “good,” such as libraries and public transportation, but the good/bad binary that has been created by the power structure doesn’t allow us to see how power functions. Of course, the state does some “good,” but the point here is that its primary function is to act on behalf of private power and not allow the masses to really have a say in social and economic policies.
The media also plays the same role, since the media is part of the power structure, based on who owns them. However, even most reporters will not question the power structure, since they have either internalized the values of the system or engage in self-censorship in order to protect their job. Very little local media is owned locally and when they do report on those with power, the news is often bias, framed in the good/bad binary and sometimes the news media acts as sort of a PR outlet for power.
This brings us to the last level in the hierarchy of power, the NGO, Social Services sector. More often than not what one sees with non-profit organizations and social services, entities that are dealing with the consequences of private power’s quest for more power – poverty, various forms of discrimination, poor health, destruction of the environment – is that these NGOs will not question the reasons why people are poor, are suffering from bad health or are the victims of discrimination and oppression.
One of the reasons for this failure to get to the root of problems within the NGO sector is because most often non-profits think that the current system is more or less fine and only needs some minor reforms. This is why many people will say that in Grand Rapids, “we do charity real well, but not justice.” There are social service agencies and charitable services all over this community, but they are not a threat to the existing power structure. This is exactly why the wealthy elites in this community often donate large sums of money to these non-profits, because they not only will not have their power threatened, it actually creates the illusion that they are doing “good.”
Radical sociologists identify the social service and non-profit sector as the first line of defense against social uprisings. If your organization or agency can provide charitable assistance to people, then they are less likely to direct their rage towards systems of power. In a sense, much of the social service and non-profit world acts as a buffer between the disenfranchised masses and the power elite or as the Occupy Movement would call them, the 1%.
This is exactly why virtually all those individuals and families who make up the 1% in Grand Rapids have their own foundations. Foundations are first and foremost a way to put one’s wealth into a non-taxable status, but it also serves as a way to create an illusion of concern, redirect attention away from social inequality and to engage in population management.
The power structure often gives money to programs that serve the “needy” as a way to guarantee that those most disenfranchised not only will not rise up against the power structure, but will actually come to see them as people they admire. We can see this all throughout West Michigan, where the DeVos, Prince, Meijer and Van Andel families are viewed with great admiration. The fact that working class people will speak highly of the local power structure is an amazing feat of propaganda that would make Joseph Goebbels blush.
The discussion at the Bloom Collective ended with looking at the function of ArtPrize within a local power analysis. People were able to deconstruct the role this art event played within that hierarchy of power and who the real beneficiaries were of the annual event.

Motivational Moment

Your progress in life begins in your own mind and ends in the same place.

Every great accomplishment began with the germ of an idea in the mind of a great person, then was shaped for practical usefulness and finally transformed into reality. Make your mind a fertile ground for ideas through constant study and learning, and condition through constant practice to discipline yourself to follow through on your good ideas. The most brilliant concept in the world is only a dream unless you take action. Even a mediocre idea that is put into practice is far more valuable than a flash of genius that languishes in a fallow, undisciplined mind.
