2. Configure the SNMP NMS
• Specify SNMPv3.
• Create the SNMPv3 user managev3user.
• Enable both authentication and privacy functions.
• Use MD5 for authentication and DES for encryption.
• Set the authentication key to authenkey and the privacy key to prikey.
• Set the timeout time and maximum number of retries.
For information about configuring the NMS, see the manual for the NMS.
NOTE:
The SNMP settings on the agent and the NMS must match.
