Gambit Changes How Network Engineers Prepare for CCNA certification

Nashua, NH (PRWEB) September 2, 2004

Gambit Communications, a leading network simulation tools provider, today announced the availability of its enhanced training tool to support Cisco (NASDAQ: CSCO) CCNA® certification. MIMIC® Virtual Lab CCNA creates a real world lab environment for training centers and network engineers with a network of Cisco Routers and Switches. It enables a hands-on learning experience without needing to buy expensive equipment.

Network engineers can practice for CCNA and other certifications instead of just reading instructions. They can interact with Cisco gear just like real devices. The realistic simulation is combined with a unique feature, “Lab Exercises”, to provide guided tutorials and exercises to practice and evaluate the readiness for the certifications.

“As a big proponent of ‘learning by doing’ I can honestly say that MIMIC Virtual Lab CCNA is the closest thing to having the real equipment in front of you,” said Matt Basham, Program Director at St. Petersburg College and the author of “Learning by Doing” CCNA Textbook. “I have tried many different simulators but none are as easy and as comprehensive as MIMIC Virtual Lab. Two thumbs up for the great product — a must have for anyone serious about Cisco certifications.”

“The MIMIC Virtual Lab makes expanding Cisco training programs easier for training organizations,” said Patrick von Schlag, President of leading IT Learning Services consultancy Deep Creek Center. “As Cisco continues to play a larger role in the IT space, leading training organizations need to expand access to multiple training labs. This is not only true for traditional for-profit training companies, but increasingly in academic settings as well. With MIMIC they can provide well-structured labs with the course material for students to practice and take home.”

MIMIC Virtual Lab CCNA consists of a simulated network of Cisco routers, switches with LAN, WAN and ISDN connections.

Some of the features include:

Lab with extensive free-form configuration

Hundreds of router commands, including all the shortcut commands and edit keys for CCNA lab training

Support for routing protocols – RIP, IGRP, EIGRP, BGP, OSPF, IS-IS

Configuration of ISDN, CDP, PPP, Frame Relay ACL and NAT protocols

Ready tutorials and exercises for different labs

Use IOS command in all modes (User, Privileged, Configuration, Interface)

Access the devices using Telnet from anywhere on the network like a real device, locally or remotely

Access the devices using the system console

Boot using flash or TFTP protocol

View the topology map with connections and addresses

Save the current configuration and reload it anytime

Troubleshoot by retracing the commands from the log

Protocol supported – Telnet, Cisco IOS, SNMPv1-3, TFTP

Question by Jamie: How can I monitor the internet bandwidth usage on my home network?
I am using Cisco (LinkSys) small business class gear model number WRV200. I have multiple computers and an xbox attached. I am only interested in network consumption though the internet. Intranet (local only) does not concern me. My ISP is Comcast. Essentially, I am looking for internet bandwidth consumed on a monthly basis. I’d prefer not to install software on each machine. Can this be done on the router?
Addendum: How can I monitor the amount of data downloaded (in GB, MB or kB) through the router described above… Cisco WRV200?

Answer by rowlfe
Excuse me? You are talking apples and oranges here. Bandwidth for your internet link is fixed by your ISP. It is always in use at full speed as set at the ISP. I’ll use a DSL link as an example. Think of DSL like a phone line that is always connected between two people. Whether you talk, listen or are silent does not change the speed of the connection via the wire. Bandwidth from your ISP is like the open phone line that whether used or not is open for communication. There is nothing to measure on your single wire between you and your ISP. At your ISP, however, THAT changes where the ISP merges you with everyone else and THERE, you now share the bandwidth the ISP has with other users. If you have a cable modem instead of a DSL, then bandwidth applies as cable is a big party line and there, you compete with everyone else for what is available from your ISP. Think of an actual telephone party line and how people can use it to talk to one another. They advertise huge amounts, but in reality only 1 user can get that speed when alone on the wire. Once there is a 2nd connection to the same cable segment, the best each can do is less than half as some is lost to overhead. The more people on the same segment of wire, the slower everyone goes. Only ONE user gets to talk at a time while everyone else is forced to wait and listen! Cable does NOT tell people that tidbit when they advertise the huge 7megabit and higher bandwidth of their system. My throughput on my 256K DSL link is better than my next door neighbor on his 7mbit cable, especially when it comes to peak usage hours, like when school gets out every weekday. I think what you meant to ask was related to the traffic carried by the link, throughput. In THAT case, your router MAY have a status screen where it shows packets sent and received and maybe it keeps logs of what happens over time. If your router does not have the logging ability built in, then the best you can hope for is to measure the throughput of each machine. You could centralize this by running your own LAN server and letting the server run and monitor the link to your ISP instead of sharing it via the router. In order to get the data you want, you need access to the router at your ISP where your data is merged with the rest of the users of your ISP. Your tiny router is a much simplified brain-dead version of the bigger smarter router at your ISP. Your tiny router only serves the couple of machines on your LAN and makes your intralan communication run effectively (packets that do not need to go to your ISP do not get routed there), but ONLY between your local few computers. It is like a traffic cop at the intersection where the lines from each of your computers meet to connect to the ferry which carries your data back and forth to and from your ISP. The ferry runs at a fixed schedule, fully loaded, half full, or empty makes no difference to the rate of travel of the ferry. The schedule is your bandwidth equivalent. What you are paying for is the link itself, NOT the amount of data actually being carried BY the link. Multimedia companies, if they get their way, instead of the fixed rate you pay today, would charge you by the number of bits transferred, so not only would they charge you for the link service itself, but in addition an added fee for each packet of data going each way as well.
