Reset enable password on cisco router

To reset enable password on cisco router use following steps:

Connect to router on console port using standard 9600 8N1 (9600 bits per second, no parity, 8-bit, 1 stop-bit, no flow control)
If console password is not set or known then use it. Use 'show version' and not current value of configuration register.
Reboot and use break sequence
Hyper-terminal

Ctrl + Break

Minicom

Ctrl+a f

Putty

Right click on title bar, choose special command -> break
On 'rommon1>' prompt use to disable loading of startup-config as running-config on system boot:
```
confreg 0x2142
```
For reboot
```
reset
```
Cancel initial configuration wizard (Ctrl+C)
Go to enable mode using enable after reboot
Get old configuration back using 'copy startup-config running-config'
Do not do reverse, else all config would be lost

Look at current configuration, reset enable password and no shut all configured interfaces using:

show running
show ip interface brief
config t
enable secret
int <int-name-number>  #for each configured interface
no shut

Again reset configuration register value so that startup configuration is copied to running-config on startup, using:
```
config t
config-register 0x2102 (or value noted before rebooting)
```
Save the entire configuration for next reboot using:
```
copy running-config startup-config
```
