Procedure


Perform the following steps to enable SNMPv3.

  1. From SBC CLI, obtain the SBC engineId using the following CLI command:

    > show table oam snmp community
    engineId 80:00:0b:3f:03:00:0c:29:c4:63:86;



  2. Use the EMS or a third-party manager to generate the authKey and privKey for SBC admin user

    Open source tools such as snmpkey can be used to generate keys if the passphrase is shared. See

    http://search.cpan.org/~dtown/Net-SNMP-5.2.0/snmpkey.PL
    for additional details.


    In this example, the generated keys are:
    <usmUserAuthKey>1E:29:3D:1C:2A:BE:67:BD:E5:B8:F0:23:56:B9:90:62</usmUserAuthKey>
    <usmUserPrivKey>1E:29:3D:1C:2A:BE:67:BD:E5:B8:F0:23:56:B9:90:62</usmUserPrivKey>

  3. From SBC CLI, enable snmpv3 for user admin on the SBC with the authKey and privKey generated from the step 2.

    % commit 



  4. From EMS or third-party manager, perform snmpwalk command to confirm SNMPv3 is working on the SBC.
