3 Levels of CCNA Announced by Cisco!

Posted in CCNA voice-security-wifi on June 24, 2008 by itdaddy

Building on the CCNA Foundation

The new suite of concentrations takes advantage of the foundation for careers in Cisco networking technologies, the CCNA certification:

  • CCNA Security validates installation, troubleshooting and monitoring skills of network devices to maintain the integrity, confidentiality and availability of data.
  • CCNA Voice validates voice application skills in voice over IP (VoIP) technologies such as IP PBX, IP telephony, handset, call control and voicemail.
  • CCNA Wireless validates a candidate’s skills in the configuration, implementation and support of Cisco wireless local-area networks (WLANs).


The new concentrations will benefit both technician and employer. Certified individuals are more successful in their jobs, and these credentials will help prepare them for new career opportunities. For employers, the certifications can validate applicant experience, and hiring companies can keep up with the demands and changes to the network and prepare current staff for the evolving network infrastructure.

With the introduction of the Cisco Learning Network and new CCNA concentrations in security, voice and wireless, Cisco is addressing talent holistically as part of its overall globalization strategy – one that is dedicated to helping companies collaborate across borders and cultures and offer world-class service to customers, regardless of location.

“Cisco has talked about collaboration for a long time, and the Cisco Learning Network is clearly not something for companies simply to use internally. Rather, it provides a way to create a community of interest around the concept of networking,” Kerravala says. “Cisco is putting its money where its mouth is here, in a way that is going to allow engineers and others to harness the power of their own community.”

Gateway command No More confusion!

Posted in Router Gateway Commands on June 15, 2008 by itdaddy


ip default-gateway (ip routing turned off when used; like windows gateway)

ip default-network (same as below defines gateway of last resort)

ip route gateway of last resort)

read below to know the difference between the last two. There is a big difference.


Here’s a couple of interesting things I learned too. One was a few months ago, trying to get a Catalyst 4500 to work with the ip default-gateway command. I configured the switch exactly as I thought it need to, but it would not connect to it’s uplink. Finally, after a bit of reading, I found out that the default-gateway command only works on layer 3 switches and routers with the “no ip routing” command. Another thing is the default network command. I’ve never seen it used, so I decided to check Cisco’s site for an explanation of it.

Apparently it’s (almost) the same thing as doing ip route (next hop ip). Here’s the difference:

Cisco wrote:
If you use both the ip default-network and ip route commands to configure candidate default networks, and the network used by the ip default-network command is known statically, the network defined with the ip default-network command takes precedence and is chosen for the gateway of last resort. Otherwise if the network used by the ip default-network command is derived by a routing protocol, the ip route command, which has a lower administrative distance, takes precedence and is chosen for the gateway of last resort.

So in short, if you have ip routing enable, use either ip default-network or ip route If you do not have ip routing enable or are working on a pure switch, use ip default-gateway. Interesting stuff.

Edit: Oh yeah, and another difference is how routing protocols treat either

command. It’s detailed in the below link.

Final Study System and Scheme!!!!

Posted in CCNA Study List hot! on June 14, 2008 by itdaddy

Okay, I have finally made up my study system. I have been racking my brain to figure out how to systematically study and cover as much material as I can for the 802 CCNA exam this 7 August 2008 that I have bought and paid for. Technically it is my first exam since my actual first 802 exam froze on me and Cisco gave me a voucher for this new 802 exam. I am going to (upon failure–I am not stupid!) take the option to do the 2nd SHOT!!! It is free and I would be stupid not to take it if they are offerring a free retake. I would take it like 1 week close to end of the 2ndSHOT avail period so I can get more study in. But damn it I think I will have this one… I have been racking my brains to find a system that will work. I believe in studying a certain way. I believe that we have certain types of memory.  For example math is in your hands. I had a civil engineering friend tell me math was in his hands. I laughed and started to use his technique. I realized maybe it is in my hands.. I try to break my studying into these blocks. I also believe we are creatures of habit and learning and remembering is nothing more than “habits of the mind!”

My CCNA 802 Study Schedule/Scheme!

1. Labs – (done Monday – Friday from 7pm to 11pm)based off of my list of topics I made!  I combine labs with smaller skillsets mixed in like Banner MOTD type commands, etc…made my own labs)

2. Cold Memory – (done weekends.) Anything I need to remember cold (AD of EIGRP = 90 or 2^5=32)

3. Quest/Answer Drills – (done weekends) practice exams (Bryant Exams bought his entire ICND1/2 course)

4. Hard CCNA TOPICs (watch CBTs) to Notes to Blog.     (done weekends)Stuff like (EIGRP,OSPF, STP, IPv6).Other stuff ACLis just lab practice till I puke but these are kind of complex dealing with timers, and unequal/equal cost load balancing and how the algorithms pick best routes.

5. Practice (done weekends).Skills like (VLSM, subnettings, supernetting, IPv6….)


Final week of exam (taking off 3 days(plus sat/sun = 5 days) before exam to practice all day and repeat all above (ALL of it)

Exam Date 7 August 2008 at 1:30PM at our towns Technical College (yeah baby! yeah!)


Make Router Frame Relay Switch

Go to Chris Bryant’s site. This is a link to his sight that teaches

how to make a cisco router into a frame relay switch (cloud) it does work!

Method of Study CCNA Topic List!

Posted in CCNA Study List hot! on June 2, 2008 by itdaddy


Method of Study:

What has puzzled me about studying for all these certs is how to handle all this information. The only way I can think of to study for this exam and other exams is to create my own system of study, and to prioritize what I study. I have done this. I combine a lot of lab skills together for exam ROS (router-on-a-stick) uses VLANS and skills to create sub-ifs so I combine maybe making banner MOTD with this lab. I try to combine as much as I can. Like labs with PAP/CHAP I combine of course setting WAN protocols like PPP or HDLC. You have to combine labs so you can jam on studying and repeating them. Use tons of debugs and read the meta data screen outputs and understand what you are doing. Damn I should pass this test! haahahah Cross your fingers. Below is my system (draft) I adjust as I go along but only to repeat skills I suck at! Like I know IPv6 cold memory stuff I will have to study much more….


Study Tool Elements:


1. Question/Answer Drills – weekend (60 question drills)
    -Bryant exams questions
    -Actual exams
    -802 exams nice
2. Labs – weekdays (2 weeks in July only)
3. CBTs – weekdays (2weeks in June only)
4. Blogs – Study major stuff 3 major elements.-  weekdays (2 weeks in july)

5. Three study memory types:

1. labs memory                                                                                                                                                2. cold memory                                                                                                                                               3. practice memory 

Note: I will be filling in the below types of memories as I study them. So once I get them together and study them, I will post them here.

My Topology Sim CITY for CCNA –  Entire Lab!


“SIMS suck!!!!!” – Get the real things: Too many bugs! %^$%&*&%#@@@@^@ I hate bugs! And incomplete command sets!!!!This week I will be back with my final lab setup for practicing CCNA 802 stuff for my exam 7 Aug 2008. I have been tossing and turning. What labs can I do on the sims and what Labs can I do on the “real thing”. Real thing I can do everything. I mean everything but Router on a stick. ROS require a Fastethernet port. I have also heard you can use a 2600 series cisco router with the right IOS image and 10 MBPS port. But I am using a sim for ROS and it works fine. But I believe I will be doing main lab topics on the real thing.But will be doing some SIM lab work (at my work during free moments) when I can. But will be back with a topology of my home setup and explaing of how I will takle this beast in under 60 days left before D day! or should I call “P” day for PASS! day! I will be back with the topology soon and explain of how I will take CCNA under 60 days.


List of topics to cover



subnetting – host-subnets
 -pat-port address trans-overload
 -dynamic nat (nat pool of addresses)
 -named      ip and protoc
 -standard   ip only
 -extended   ip and protoc
 -frame-relay map ip  – static – inverse arp is disabled
 -frame-relay interface-dlci – using inverse arp
 -EIGRP – Dual – multicast
 -OSPF – Djkstra – multicast
 -RIPv2 -broadcast
 -VTP and tagging (vlan) 802.1Q
 -STP 802.1D
 -port security
 -wpa (aes) encryption types
 -virtual interface (wifi needs ip address)
 -pap – not same passwords needed (passwd sent clear text)
 -chap – same passwords needed. (passwed info sent only not passwd)
 -ssh setup
Router Basics
 -copy flash TFTP
 -copy running-config TFTP
