…done Initializing Flash.
switch:
Find the config file in flash: directory
The files that we are looking for in the flash: directory is the config.text file.
Directory of flash:/
3 -rwx 2296 vlan.dat
4 -rwx 3569 config.text
5 -rwx 5 private-config.text
6 drwx 192 c2960-lanbasek9-mz.122-55.SE7
562 -rwx 2072 multiple-fs
Rename the config file so that it will not be loaded when we boot to the switch.
Then type the below command to boot to the switch
After booting, the switch will ask you to enter the "initial configuration dialog" to initially configure the switch using interactive CLI mode. Just type the word "no" because we are not re-configuring the switch.
— System Configuration Dialog — Enable secret warning ———————————- In order to access the device manager, an enable secret is required If you enter the initial configuration dialog, you will be prompted for the enable secret If you choose not to enter the intial configuration dialog, or if you exit setup without setting the enable secret, please set an enable secret using the following CLI in configuration mode- enable secret 0 ———————————- Would you like to enter the initial configuration dialog? [yes/no]: no
At the switch prompt type en to enter enable mode.
Rename the configuration file to its original filename.
Copy the configuration file into the memory
Now that the config is loaded in to the memory, we can start changing the password.
enable secret newpassword
After changing the password, save the config and done.
This tutorial will also work on Cisco 2950 switches. Hope this helps.
