Use the following procedure to change IP addresses and users for SNMP v3 request authentication.

You must have the Storage Administrator (Initial Configuration) role to perform this task.

  1. In the maintenance utility, click Administration > Alert Notifications.
  2. In the Alert Notifications window, click Set Up.
  3. In the Set Up Alert Notifications window, select the SNMP tab.
  4. Under SNMP Agent, click Enable.
  5. Under SNMP Version, select v3.
  6. Under Registered Request Authentication Settings, select an authentication setting that you want to change, and then click Change.
  7. In the Change Request Authentication Setting window, under User Name, enter a user name.
    Note:
    • If you use a user name that has already been specified for Sending Trap Setting or Request Authentication Setting, specify the same settings for the following options that were specified for that name. Otherwise, SNMP traps might not be sent correctly.
      • Authentication
      • Authentication - Protocol
      • Authentication - Password
      • Encryption
      • Encryption - Protocol
      • Encryption - Key
    • If User Name is grayed out and you cannot enter the value, delete the registered settings for that user, and then add the settings for the user again. For details, see Deleting SNMP request authentication and Adding request authentication for SNMP v3.

    You can enter up to 32 letters, numbers, and symbols, except the following: 

    " \ ; : , * ? < > | / ^ & %

    Do not use a space at the beginning or end of the name.

  8. Under Authentication, select whether to Enable or Disable authentication.
    If you select Enable, complete the following steps:
    1. For Protocol, select an authentication type.
    2. If you change your password, check the Change Password checkbox, and then enter a password.
    Note: The protocols (authentication types) you can select differ depending on the security mode settings as shown in the following table. Only the selectable protocols are displayed.
    Security mode Protocol (Authentication type)
    SHA SHA-256 SHA-384
    FIPS Yes Yes Yes
    CNSA1.0 No No Yes
  9. Under Encryption, select whether to Enable or Disable encryption.
    If you select Enable, complete the following steps:
    1. For Protocol, select an encryption type.
    2. If you change a key, check the Change Key checkbox, and then enter a key.
    3. For Re-enter Key, enter the same key for confirmation.
    Note: The protocols (encryption types) you can select differ depending on the security mode settings as shown in the following table. Only the selectable protocols are displayed.
    Security mode Protocol (Encryption type)
    DES AES AES-256
    FIPS Yes Yes Yes
    CNSA1.0 No No Yes
  10. Click OK.
    The user you entered is changed to the Registered Request Authentication Settings table.
  11. Confirm the settings, and then click Apply.
    Note:

    If the setting of Protocol does not conform to CNSA1.0, SIM reference code 7d23xx is output. In that case, change the setting of Protocol to the encryption type that conform to the security mode CNSA1.0.

    If the cause of the SIM is resolved, SIM 7d24xx is output. In that case, in the Alert Notification of the maintenance utility, complete SIMs 7d23xx and 7d24xx.

    If SIM 7d24xx is not output even after the setting of Protocol is changed, in the Set Up Alert Notifications window, confirm that all Protocol settings are correct.
