Switch credentials

  • This section describes how to change the administrator (admin) and Simple Network Management Protocol (SNMP) credentials on all switches.

    Note: All Admin and Enable account passwords must be the same for all switches in a scale unit.

    Prerequisites

    Before you run the procedures:

    • Use Remote Desktop to connect to the HLH.
    • Locate PuTTY on the HLH, usually E:\Tools\Putty\putty.exe. If PuTTY is not available, download and copy it onto the HLH.
    • Ensure that you have both the current and new credentials for the switches.

    Updating Admin and Enable account credentials

    Procedure

    For each switch in the scale unit (BMC, TOR1, and TOR2):

    1. On the HLH, using PuTTY, log in to the switch using the current credentials.
    1. Run the following command, replacing <new password> with your new admin and enable credentials:

    enable

    configuration terminal

    username admin password <new_password> privilege 15

    enable password <new_password>

    1. Leave the current session open to the switch.
    2. On the HLH, using PuTTY, log in to the switch using the new credentials.
    3. Run the following command. Enable should not prompt for a password:

    enable

    write

    dir flash:

    1. Verify that the startup-config has today’s date.
    2. On confirmation, close both this session and the original session.

    Updating SNMP accounts

    Procedure

    For each switch in the scale unit (BMC, TOR1, and TOR2):

    1. On the HLH, using PuTTY, log in to the switch.
    1. Run the following command to obtain the current SNMP read/write users or groups:

    enable

    show run snmp | grep user

    The following example shows the type of content that is returned, including user, group name, and passwords hashes:

    snmp-server user <user> <group> 3 encrypted auth sha <password_hash>

    1. Run the following command, replacing <user> and <group> with the details determined from the previous step, and replacing <password> with your new password:

    configuration terminal

    snmp-server user <user> <group> 3 auth sha <password_new>

    end

    write

    exit

    Next step
