Need Help resetting 3650

[Derickt]

Needing a little help here please. I have inherited a C3650-48PQ switch that was running as a core switch. I am trying to clear configs on it and initialize it as a standalone switch in a lab environment.

So far I have been able to remove vlan.dat and clear start-up confiig. However, when reloading, I do not get the initial config prompt.

I do not see any config.txt file in any directory.

Any help would be appreciated.

if you can not enter enable more then you need reset factory if you dont have old enable password 

[Derickt]

I am able to enter enable and get Switch#

I have also followed the instructions step by step on resetting to factory,

[balaji.bandi]

Generally, if you have access to # prompt try below - works for me several times :

#copy running flash:myold.cfg
#write erase  (Enter to confirm)
#reload

still issue? post complete boot

Switch>    - this means config was reset to factor ?

you looking to get  initial config wizard how you get when you open tip out of box as below :

Would you like to enter the initial configuration dialog? [yes/no]:

1. Power down the switch removing power cable.

2. Hold down MODE button. (connect the Power cable)

3. you see switch: prompt

4. switch : flash_init

5.  switch: rename flash:config.text flash:config.old

6. switch: set SWITCH_IGNORE_STARTUP_CFG=0

7  switch : boot

[Derickt]

No flash:config.txt

[balaji.bandi]

No flash:config.txt   <-- not sure where you got this device from - looks may be deleted (that's what most engineers do when they remove from the network - erase the config or delete it)

#dir shows you what files in the flash or post here the output.

How to Perform Factory Reset

Procedure

	Command or Action	Purpose
Step 1	enable Example: Device> enable	Enables privileged EXEC mode. Enter your password if prompted.
Step 2	configure terminal Example: Device# configure terminal	Enters global configuration mode.
Step 3	factory-reset { all | config | boot-vars} Example: Device(config)# factory-reset all	Use the command with all options enabled. No system configuration is required to use the factory reset command. Erases all the content from the NVRAM, all the Cisco IOS images, including the current boot image, boot variables, startup and running configuration data, and user data. After the Factory Reset process is successfully completed, the device reboots and stops at ROMMON mode.

Look at the config guide for configuration files.

[balaji.bandi]

in the original post, I was thinking old switch, when you post the boot log, it is running IOS XE

so I have posted the guide to reset to the factory using the command that should fix your issue.

[Derickt]

Just noticed this during reload, is there a way to reset the default config?
