switch# configure terminal

switch(config)# exit
switch#

switch# copy running-config startup-config
Power Cycling the Switch
If you cannot start a session on the switch that has network-admin privileges, you must recover the
network administrator password by power cycling the switch.
Caution This procedure disrupts all traffic on the switch.
Note You cannot recover the administrator password from a Telnet or SSH session. You must have access to
the local console connection.
To recover the network administrator password by power cycling the switch, follow these steps:
Step 1 Establish a terminal session on the console port of the supervisor module.
Step 2 Power cycle the switch.
Step 3 Press the Ctrl-] key sequence from the console port session when the switch begins the Cisco NX-OS
software boot sequence to enter the boot prompt mode.
Ctrl-]
switch(boot)#
Step 4 Reset the network administrator password.
switch(boot)# configure terminal
switch(boot-config)# admin-password <new password>
switch(boot-config)# exit
switch(boot)#
Step 5 Display the bootflash: contents to locate the Cisco NX-OS software image file.
switch(boot)# dir bootflash:
Step 6 Load the Cisco NX-OS system software image.
In the following example, the system image filename is nx-os.bin:
switch(boot) # load bootflash:nx-os.bin
Step 7 Log in to the switch using the new administrator password.
switch login: admin
Password: <new password>
