Cisco 9300 switch lost username and password

[rajaram855]

Hi,

Is this the only procedure to reset or change the username and password in Cisco 9300 switches?

during this below reload the network will go down?

switch: SWITCH_IGNORE_STRATUP_CFG=1
SWITCH>EN
SWITCH#
SWITCH#SH RUN | INC USERNAME
SWITCH# SH STARTUP-CONFIG | INC USERNAME
SWITCH#COPY STARTUP-CONFIG RUNNING-CONFIG
SWITCH#CONF T
SWITCH(config)#username xxxx privilege 15 secret xxxx  => username and password
SWITCH(config)#no system ignore startup-config switch all
SWITCH(config)#exit
switch#wr

can you help me any other way to reset or change the username and password in cisco 9300 without reload.

Thanks!

yes the process you mentioned was network service interruptive, that is the reason always maintain central authentication system so TACACS/Radius can take care of that authentication to avoid this situation.

Also create emergency account in case required to break in - in case you lost other username and password. (store centrally some where secure)
