![]() We will now copy the startup-configuration to the running-configuration ourselves. Great! We now have full access to the router and it didn’t prompt for a password. We will now go to enable mode: Router> enable Just type no and you will end up at the command-line. Would you like to enter the initial configuration dialog? : noīecause the router is not loading its startup-configuration it will show you the wizard that is shown when there is no configuration. The router will boot and load its IOS image, once it’s ready you will see the following wizard: - System Configuration Dialog. ![]() Program load complete, entry point: 0x8000f000, size: 0x38bbd64 Program load complete, entry point: 0x8000f000, size: 0xcb80 Main memory is configured to 64 bit mode with ECC enabled The router is nice enough to tell us we should reboot so let’s follow its advice: rommon 2 > resetĬ2811 platform with 786432 Kbytes of main memory This tells the router to ignore the startup-configuration when booting. We set the configuration-register to 0x2142 with the confreg command. You must reset or power cycle for new config to take effect Here’s how to do it: rommon 1 > confreg 0x2142 This is exactly what we want because it means it will also not load the password that we configured (and forgot). We can only configure a couple of items here, one of the things we can do is tell the router to ignore it’s startup-configuration when booting the IOS image. This tells us that we are in ROMMON mode. Here’s what it looks like: Readonly ROMMON initialized ROMMON is like a mini operating system that helps to initialize the hardware and boots the Cisco IOS. When the router accepts your BREAK it will head into ROMMON mode. If this doesn’t work you can try some of the other methods that are described here. If you are using Windows and Putty you can probably use the CTRL-BREAK combination to send a break signal. This tells the router to ignore loading the IOS (Cisco’s Operating System). Reboot the router (just hit the power switch) and send the BREAK signal. To fix this problem you need to connect your router to the console port, you can’t do this remotely through telnet or SSH. Ouch…bad secrets means we didn’t type the correct password. This only applies to routers, if you need to reset the password for a switch then you need another lesson. Whatever the reason, let me show you how to reset the password of your Cisco router. Maybe you need to reset the password of a router you didn’t configure… Replace the value with secret identifier from step5 of update Key-Vault with new client secret and save the settings.It happens to the best of us, you are doing some labs and forgot what password you set for enable mode…perhaps another student was working on the router before and you have no idea what password he picked. In case of Azure AD tenant, search for 'idp:AzureADExternalAuthClientSecret' and click on it. Windows shows you drop-down boxes for three security questions.
