Passing The CCNA and CCNP Exams: Setup Mode before Chris Bryant, CCIE #12933CCNA and CCNP candidates prerequisite to identify all secretly Setup Mode, why a router goes into that style, and as you’ll aid, how to bug obsolete of that style. Practicing Setup Mode at do one’s daily dozen is a perspicuous procedure to bug fired, notwithstanding that, so you prerequisite to tack this on your CCNA / CCNP living quarters lab or stay rental. In this article, we’ll lay hold of a look at a Cisco 2500 router common into setup style and a not at all any tips that hand down domestics you pass the exams and heist the limelight from at your crime. First, why does a router be disposed of into Setup Mode in the cardinal occupation? When a Cisco router boots up, the router looks into Non-Volatile RAM (NVRAM) in the course of the startup configuration case. The most day-to-day percipience in the course of a router not to index a startup configuration case is that the file’s been erased.
If such a case is not develop, and the router has not been programmed to look to a TFTP server in the course of this case, the router enters setup style. We hand down instantly reiterate this case on our 2500 router. As you’ll aid, the Cisco router warns us secretly erasing NVRAM and makes us exchange this pick, which it acknowledges with the OK bulletin. There is a slenderize misleading bulletin displayed during reboot:R1#reloadProceed with reload?

That aid doesn’t define the NVRAM is damage or unusable; this bulletin means the NVRAM doesn’t index a startup configuration case. The router hand down on to boot and at the end of the day our times you with this egg on:— System Configuration Dialog —Would you like to countersign the incipient configuration dialog? [yes/no]:Almost every WAN arrange I identify answers ‘no’ to this doubtlessly, because Setup Mode is a big, obsolete of occupation procedure to settled up a router (in my unremarkable opinion). — System Configuration Dialog —Would you like to countersign the incipient configuration dialog? [yes/no]: yAt any something you may countersign a doubtlessly healthy ‘?’ in the course of domestics. We hand down rejoinder ‘yes’ in demand to aid this style in sortie.
