Wipe Management Switch Configuration

This procedure describes how to wipe Aruba, Dell, and Mellanox switch configurations.

Prerequisites

Out-of-band access to the switches (console)

Aruba

  1. Create a checkpoint before erasing the switch configuration.

    More information related to backing up configuration can be found on the Configuration Management procedure.

    sw-spine-001# copy running-config checkpoint CSM1_0

  2. Verify the checkpoint was created.

    sw-spine-001# show checkpoint

    Example output:

    NAME                         TYPE        WRITER  DATE(YYYY/MM/DD)      IMAGE VERSION
CSM1_0                       latest      User    2022-01-27T18:52:31Z  GL.10.08.1021

  3. Erase the startup configuration.

    sw-spine-002# erase startup-config
Erase checkpoint startup-config ? (y/n): y

  4. Reboot after erasing the startup configuration.

    sw-spine-001# boot system
Checking if the configuration needs to be saved...

Do you want to save the current configuration (y/n)? n

    The switch will reboot without any configuration.

    The default user is admin without any password.

  5. Follow the Apply Switch Configurations procedure.

Dell

  1. Save startup configuration to a new XML configuration file.

    sw-leaf-bmc-001# copy config://startup.xml config://csm1.2.xml

  2. Erase the startup configuration.

    sw-leaf-bmc-001# delete startup-configuration
Proceed to delete startup-configuration [confirm yes/no(default)]:yes

  3. Reboot after erasing the startup configuration.

    sw-leaf-bmc-001# reload
System configuration has been modified. Save? [yes/no]:no
Continuing without saving system configuration
Proceed to reboot the system? [confirm yes/no]:yes

    The default username and password are admin. This will boot the switch to factory defaults.

  4. Follow the Apply Switch Configurations procedure.

Mellanox

  1. Create a new configuration file.

    When a new configuration file is created, no data is written to it. We will boot to this new, blank configuration file.

    (config) # configuration new csm1.2

    If that configuration exists already, delete it with configuration delete csm1.2, or reset to factory defaults with reset factory.

  2. Check that the configuration files contain the new csm1.2 blank configuration that was just created.

    (config) # show configuration files

    Example output:

    files
csm1.0 (active)
csm1.2
initial
initial.bak
Active configuration: csm1.0
Unsaved changes : no

  3. Switch to the new configuration, which requires a reboot.

    (config) # configuration switch-to csm1.2
This requires a reboot.
Type 'yes' to confirm: yes

    The default username and password are admin

  4. Follow the prompts as shown below.
