Power Cycling the Switch
Example:
switch# show user-account
user:admin
this user account has no expiry date
roles:network-admin
user:dbgusr
this user account has no expiry date
roles:network-admin network-operator
Step 2 If your user name has network-admin privileges, issue the username command to assign a new administrator
password.
Example:
switch# configure terminal
switch(config)# username admin password
switch(config)# exit
switch#
Step 3
Save the software configuration.
Example:
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 administrator
password by power cycling the switch.
Caution This procedure disrupts all traffic on the switch. All connections to the switch will be lost for 2 to 3 minutes.
Note You cannot recover the administrator password from a Telnet or SSH session. You must have access to the
local console connection. See the Cisco MDS 9000 Family NX-OS Fundamentals Configuration Guide for
information on setting up the console connection.
To recover a administrator password by power cycling the switch, follow these steps:
Procedure
Step 1
For Cisco MDS 9500 Series switches with two supervisor modules, remove the supervisor module in slot 6
from the chassis.
Note

On the Cisco MDS 9500 Series, the password recovery procedure must be performed on the active
supervisor module. Removing the supervisor module in slot 6 ensures that a switchover will not
occur during the password recovery procedure.
