Procedure

Perform the following steps to enable SNMPv3.

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

   Code Block
   language none
   > 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

   Info
   Open source tools such as snmpkey can be used to generate keys if the passphrase is shared. See Link_in_new_tab Text http://search.cpan.org/~dtown/Net-SNMP-5.2.0/snmpkey.PL URL 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.

   Code Block
   language none
   > configure Entering configuration mode private [ok][2015-02-06 06:06:46] [edit] % set oam snmp securityLevel authPriv version v3only users admin authProtocol HMACMD5 authKey 1E:29:3D:1C:2A:BE:67:BD:E5:B8:F0:23:56:B9:90:62 privProtocol DES privKey 1E:29:3D:1C:2A:BE:67:BD:E5:B8:F0:23:56:B9:90:62 group admin % commit

   
   
   

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