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

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!
