1  Cisco / CCNA / what cisco cert after ccna??? on: April 28, 2005, 05:25:35 AM
90% of people who go for the CCIE lab test fail first time. They say it takes 4-5 times to pass on average so each run before that should be treated like a practice run.

There are only 12000 CCIE's in the world. Hell this thing is harder to get than a medical/Doctorate degree and it should be more valued. It takes years and years of dedication and study.

I would go CCNP first. It is still hard to get.

CCIE is only if you know that you want to stay in the networking business for the rest of your life and you want to be earning good money.
2  Cisco / CCNA / designated port?? on: April 28, 2005, 05:11:52 AM
Remember 1 designated port per segment. Designated ports are always in the foewarding state.
3  Cisco / CCNA / don`t know which book to buy, what do you recommend on: April 28, 2005, 05:06:56 AM
Any cisco certified book by Odom or McQuerry.
I used both and got a lot out of it.

Read at least one of them twice.

The sims have limited functionality, just enough for what you are assigned to do. Shortcut commands can be used - but not all of them.  

? will show one level of the commands and I don't think tab shortcuts are available.

To be honest I was so pressed for time I didn't explore everything.

Just a tip. No computer calculator is given which will slow you down. Know your subnetting tables well.


A mask of 240 will give you

subnets of 0, 16, 32, 48, 64 etc.
5  Cisco / CCNP / Which exam to begin CCNP on: April 20, 2005, 11:01:49 PM

Thanks guys.

Have a good Anzac day to both of you Smiley
6  Cisco / CCNP / Which exam to begin CCNP on: April 20, 2005, 07:52:46 AM
Sorry to ask this question which has probably been answered before.

What exam paths have people taken here to get the CCNP.

Should I take the BSCI & BCMSN seperately

or the composite exam which comprises them both.

I gather there are 4 or 3 exams to take.

I took 4 months to get the CCNA, so should take a 8 - 12 Months getting the CCNP
7  Cisco / CCNA / passing mark on: April 19, 2005, 04:08:16 AM

That doesn't mean you need 85%.

Cisco uses a grading system on each question right through the whole test. You might just get 70% right but will still pass. Some questions are not scored. Cisco puts them in the test to see how people deal with them.

I have heard people skipping two sim questions and still passing.
8  Cisco / CCNA / Sim vs real equipment on: April 19, 2005, 03:58:13 AM
Boson netsim does the job if you just want to do the CCNA.

Buy the hardware if you want to pursue networking as a career.

2600 series routers support Fast ethernet which is needed to set up router on a stick. Provided you have a 2900 + series switch. Otherwise 2500 router or 1900 switch will connect everything fine. CCNA exam doesn't support 1900 series switch any more though.

I got the OSPF sim. One sim only, which means a lot more other questions which require a bit longer to work out. Cisco recommends 10 mins to spend on the sim questions.

Just a tip use show run to work out the OSPF problem then act from there.

I have heard about the Nat sim. It's hard. I suggest if you are taking the test read up on nat overloading at the cisco website because the textbooks don't cover all the information on it.

Use Boson Netsim or real routers to practise commands.
10  Cisco / CCNA / Just Passed! - Phew on: April 08, 2005, 11:06:45 AM
Passed with 854 - 849 to pass.

What got me was the 55q in 90 mins. I took too long on some of them and I was expecting a fail score. Passing was a surprise.

Know Subnetting, ACL's, Routing Protocols, OSI mapping, Router config and troubleshooting well.

Some good sites are

The cisco CCNA prep centre - Joining is free

and for heaps of good prac questions

Thanks and Good luck
11  Cisco / CCNA / Best book for CCNA? on: March 23, 2005, 10:44:32 AM
I'm using Cisco self study books - which I bought and the Wendell Odom intro and ICND pdf versions. The cisco books cover about 750 pages or so where as the Odom books go over the 1000 page mark. Overall I would say The odom books cover the topics slightly better but I don't like how every command answer is shown via the show run output. The cisco books are more straight to the point but harder to understand. It took me 3 months to go through both though. I still forget stuff and have to re-read topics.

Also I have the boson netsim cd which has over 100 labs to study from. It is quite comprehensive but doesn't support all the high level commands which a real router would.
12  Cisco / CCNA / How many Mac addresses to a switch? on: March 17, 2005, 03:43:45 AM
I don't know? but can I get fries with that..ha

Grimace where's Ronald McDonald when you need him..ha

What's that Grimace? How many quarters to a router? --> Try asking Hamburglar

Oh yeah that's right. Hamburglar got done for snorting coke and molesting kids at parties...bummer!

No seriously

Something I'm a bit hazy on.

sh int comes up with a different mac address on each switch port.

Does every switch port have its own in-built mac address or is just one Mac address to the whole switch. I'm talking about a switch with nothing plugged into it.
13  Cisco / CCNA / Cant ping from router to router on: March 17, 2005, 03:14:32 AM
Maybe you can tell us your network setup, what cables you're using to join the routers, and if any of the other config files are different from the one displayed below. I notice you have the clock rate set on serial 0, so are you using back to back serial cable. Telnet but no icmp, does one of the joining routers have an access-list on it?
14  Cisco / CCNA / Core Switch and Vlans ? on: March 14, 2005, 03:39:06 AM
I have worked in a big network which used them but I never got to understand what they did fully before I left that job.

Is this what they are and do.I couldn't really find any good data on them so I'm just guessing. Please correct me if I'm wrong:

They act as a central management switch are based in your data center/server room etc. Then off these run swicthes to your floors which connect your users. The core switch runs as a VLAN Membership Policy Server (VMPS). It uses a different operating system than a IOS based switch. On it you set up a particular Vlan, and assign it an IP subnet range. The vlan database on the core holds the mapping of mac addresses to vlan assignment. So when you add a dynamic port to a vlan on a floor switch. The computer's MAC address is learned by the core switch and it is mapped to a particular Vlan.

So if the above is correct no IOS switch can act as a central vlan repository. An IOS switch can only have a management IP which you telnet into, it can't have an IP subnet representing a particular Vlan, but it can have computers running from it who reside in different vlan subnets.
15  Cisco / CCNA / Difference Between 2924 and 2950 switch on: March 12, 2005, 11:42:35 PM
2950's are expensive just for a home lab.

I purchased a 2924 on ebay for $250 and it seems good but the commands are slightly different than the 2950 judging by my books.

If you have the money or your company is paying for your CCNA go the 2950.

However even a 1900 will do, but make sure they are the enterprise version which has the CLI on it. 1900's only have 1-2 fast ethernet ports though. I also purchased a 1900 standard switch which uses a menu system, which is ok for just plugging in cable.

So I have 2 2501's routers, a 2924 and a 1900 switch inc 2 Aui/eth converters and 2 DTE/DCE cables. I played around with my lab for a while but now i just mostly use my router sim program which is quicker - Boson CCNA netsim. Even that doesn't support everything I want to do though.
