Type set at the boot# prompt, and record the current value of the configuration register.
boot#set set baud =9600 set data-bits =8 set parity =none set stop-bits =1 set console-flags =0 set mac-address =0050.7307.C329 set unit-ip =10.200.40.65 set serv-ip =255.255.255.255 set netmask =255.255.252.0 set gate-ip =10.200.40.1 set pkt-timeout =8 set tftp-timeout =16 set boot-action =flash set file-name ="c800-nsy6-mw.122-10b.bin" set watchdog =off set prompt ="boot" set ios-conf =0x2102!--- The ios-conf variable sets the value for the !--- configuration register. Record this value.
Type set ios-conf = 142 at the boot# prompt.
Note: The best setting is 142 if the Flash is intact. If the Flash is not installed or is erased, use 141. With this setting, you can view or erase the configuration, but you cannot change the password.
Type boot at the boot# prompt in order to initialize the router.
The router reboots, but ignores the saved configuration.
Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure.
Type enable at the Router> prompt.
Once the Router# prompt appears, you are in enable mode.
Type configure memory or copy startup-config running-config in order to copy the nonvolatile RAM (NVRAM) into memory.
Important: Do not type copy running-config startup-config or write. These commands erase your startup configuration.
Type show running-config.
The show running-config command shows the configuration of the router. In this configuration, the shutdown command appears under all interfaces, which indicates all interfaces are currently shut down. In addition, the passwords (enable password, enable secret, vty, console passwords) are in either an encrypted or unencrypted format. You can reuse unencrypted passwords. You must change encrypted passwords to a new password.
Type configure terminal.
The hostname(config)# prompt appears.
Type enable secret in order to change the enable secret password. For example:
hostname(config)#enable secret cisco
Issue the no shutdown command on every interface that you use.
If you issue a show ip interface brief command, every interface that you want to use displays up up.
Type config-register . Where configuration_register_setting is either the value you recorded in step 2 or 0x2102 . For example:
Press Ctrl-z or end in order to leave the configuration mode.
The hostname# prompt appears.
Type write mem or copy running startup in order to commit the changes.
Once the router reloads, the configuration register value changes from 0x142 to 0x2102.
recover username and password for 870 series router
Even if I reset the secret password, how do I find what the username is?
You can create a new Username/Password of your choice when you perform password recovery.
IF this is a brand new router and you want to start from scratch, look behind the 870 router. There's a RESET button. Power down the router, hold down the reset button, and power up the router. Wait for 5 seconds before releasing the reset button.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
