2. Configure the SNMP NMS:
{
Specify the SNMP version for the NMS as v3.
{
Create two SNMP users: managev3user and public.
{
Enable both authentication and privacy functions.
{
Use MD5 for authentication and DES for encryption.
{
Set the authentication key to authkey and the privacy key to prikey.
{
Set the timeout time and maximum number of retries.
For information about configuring the NMS, see the NMS manual.
NOTE:
The SNMP settings on the agent and the NMS must match.
