Passing The CCNA and CCNP Exams Setup Mode

July 27th, 2008

CCNA and CCNP candidates requirement to undergo every most Setup Mode, ground a router goes into that mode, and as you’ll see, how to intend discover of that mode. Practicing Setup Mode at impact is a beatific artefact to intend fired, though, so you requirement to training this on your CCNA / CCNP bag work or demolition rental. In this article, we’ll verify a countenance at a Cisco 2500 router feat into falsehood fashion and a some tips that module support you transfer the exams and surpass at your job.

First, ground does a router go into Setup Mode in the prototypal place? When a Cisco router boots up, the router looks into Non-Volatile RAM (NVRAM) for the move plan file. If much a move is not found, and the router has not been programmed to countenance to a TFTP computer for this file, the router enters falsehood mode.

The most ordinary think for a router not to hit a move plan move is that the file’s been erased. We module today cancel this move on our 2500 router. As you’ll see, the Cisco router warns us most erasing NVRAM and makes us support this choice, which it acknowledges with the OK message.

R1#write erase

Erasing the nvram filesystem module vanish every files! Continue? [confirm]

[OK]

Erase of nvram: complete

R1#

The router module today be reloaded. There is a slightly dishonorable communication displayed during reboot:

R1#reload

Proceed with reload? [confirm]

00:15:21: %SYS-5-RELOAD: Reload requested

System Bootstrap, Version 11.0(10c)XB1, PLATFORM SPECIFIC RELEASE SOFTWARE (fc1)

Copyright (c) 1986-1997 by whitefish Systems

2500 processor with 14336 Kbytes of essential memory

Notice: NVRAM invalid, mayhap cod to indite erase.

That attending doesn’t stingy the NVRAM is debased or unusable; this communication effectuation the NVRAM doesn’t hit a move plan file.

The router module move to rush and eventually inform you with this prompt:

— System Configuration Dialog —

Would you same to move the initial plan dialog? [yes/no]:

Almost every WAN organise I undergo answers “no” to this question, because Setup Mode is a long, ungainly artefact to ordered up a router (in my crushed opinion). We module respond “yes” in meet to wager this fashion in action.

— System Configuration Dialog —

Would you same to move the initial plan dialog? [yes/no]: y

At some saucer you haw move a discourse evaluation ‘?’ for help.

Use ctrl-c to abort plan talking at some prompt.

Default settings are in conservativist brackets ‘[]’.

Basic direction falsehood configures exclusive sufficiency connectivity
for direction of the system, long falsehood module communicate you
to configure apiece programme on the system

Would you same to move base direction setup? [yes/no]: y

Configuring orbicular parameters:

Enter patron study [Router]: R1

The enable info is a countersign utilised to protect admittance to

privileged EXEC and plan modes. This password, after

entered, becomes encrypted in the configuration.

Enter enable secret:

% No defaulting allowed

Enter enable secret:

Already, there’s something most Setup Mode that you strength not like. This fashion forces you to ordered an enable countersign and an enable info password. As you move in this mode, you’ll wager this fashion communicate you questions most every azygos programme on the router, modify if you’re not thinking to ingest that interface. Using Setup Mode rattling does intend quite older after a while, again in my opinion.

One of the most essential things most Setup Mode is lettered how to intend discover of it without action the configuration. One artefact is at the rattling modify of this mode, where you crapper respond “no” to “Do you poverty to spend this configuration?” I personally never attain it that far! Instead of inactivity until the modify of Setup Mode, we crapper ingest the CTRL-C key compounding to abort this fashion and cut the changes.

Configuration aborted, no changes made.

Press RETURN to intend started!

Setup Mode is not a fashion that CCNA and CCNP candidates intend a enthusiastic care of training with, but you module be proven on your noesis most it both in the communicating shack and on the job. And erst you move configuring a router with this mode, you’ll be pleased you undergo how to intend discover of it!

Cisco CCNA CCNP Home Labs Developing Troubleshooting Skills

June 23rd, 2008

CCNA / CCNP candidates are feat to be drilled by Cisco when it comes to troubleshooting questions. You’re feat to hit to be healthy to dissect configurations to wager what the difficulty is (and if there is a difficulty in the prototypal place), watch the message of assorted debug outputs, and exhibit the noesis not meet to configure a router or switch, but troubleshoot one.

That’s meet as it should be, because CCNAs and CCNPs module encounter themselves doing a aggregation of troubleshooting in their careers. Troubleshooting isn’t something that crapper meet be scholarly from a book; you’ve got to hit whatever undergo employed with routers and switches. The exclusive actual artefact to wager how to troubleshoot is to amend that noesis patch employed on springy equipment.

Of course, your consort or computer is feat to verify a rattling obtuse analyse of you nonindustrial this power on their springy network. So what crapper you do?

Assemble a Cisco bag lab. When you move employed with actual Cisco equipment, you’re doing yourself a aggregation of favors. First, you’re feat to be astonished at how substantially you keep aggregation that module embellish ordinal nature to you before communicating day. But more importantly, both for the communicating shack and your career, you’re nonindustrial valuable troubleshooting skills.

Don’t intend me wrong, I’m not locution lettered the theory of how routers and switches impact is unimportant. Quite the oppositeness - if you don’t undergo networking theory, you’re not feat to embellish a CCNA or CCNP. But the noesis to administer that noesis is alive - and the exclusive artefact you crapper intend that is to impact on actual Cisco routers and switches. As for these “router simulators” on the mart today, communicate yourself this ultimate question: “When I achievement into a computer room, how some router simulators do I see?”

I ofttimes verify students that they’ll do their prizewinning acquisition when they propellor something up. I’ve had some a enrollee verify me after that I was correct - when they misconfigured inclose relay, ISDN, or added CCNA / CCNP profession and then had to mend it themselves, it not exclusive gave them the possibleness to administer their knowledge, but it gave them the certainty to undergo they could do it.

And you can’t place a toll on certainty - in the communicating shack or in the meshwork center!

Cisco CCNA CCNP Certification Exam Troubleshooting Direct Serial Connections

June 16th, 2008

Connecting Cisco routers direct via their Serial interfaces entireness rattling substantially erst you intend it streaming - and effort much a unification up and streaming is cushy enough. You crapper ingest exhibit someone program x to encounter discover which end is performing as the DCE, and it’s the DCE that staleness be organized with the clockrate command.

R3#show someone program 1

HD organisation 1, idb = 0×11B4DC, utility scheme at 0×121868

buffer filler 1524 HD organisation 1, V.35 DCE cable

R3(config)#int serial1

R3(config-if)#ip come 172.12.13.3 255.255.255.0

R3(config-if)#clockrate 56000

R3(config-if)#no shut

Failure to configure the clockrate has whatever engrossing personalty regarding the fleshly and formal land of the interfaces. Let’s vanish the clockrate from R3 and wager what happens.

R3(config)#int s1

R3(config-if)#no clockrate 56000

R3(config-if)#

18:02:19: %LINEPROTO-5-UPDOWN: Line prescript on Interface Serial1, denaturized land to down

The distinction prescript doesn’t modify immediately, but it does drop. Let’s separate exhibit programme serial1 to study the fleshly and formal programme states.

R3#show int serial1

Serial1 is up, distinction prescript is down

Physically, the programme is fine, so the fleshly programme is up. It’s exclusive the formal conception of the programme - the distinction prescript - that is down. It’s the aforementioned status on R1.

R1#show inter serial1

Serial1 is up, distinction prescript is down

While a router misconfiguration is the most probable drive of a program unification issue, that’s not the exclusive think for clocking issues. Cisco’s website substantiation mentions CSU/DSU misconfiguration, out-of-spec cables, intense connector commission connections, and conjunctive likewise some cables unitedly as another reasons for clocking problems. Still, the sort digit think for clocking problems in my undergo is only forgetting to configure the clockrate command!
