Changing the Authentication Protocol for an SNMP v3 Node

If you change the authentication protocol on an SNMP v3 agent, you must likewise change the protocol used by NerveCenter to manage that agent.

An authentication protocol must be specified when the node's security level is AuthNoPriv or AuthPriv. NerveCenter supports either HMAC-MD5-96 (MD5) or HMAC-SHA-96 (SHA) as authentication protocols. The default is MD5.

 
  To change the authentication protocol used by NerveCenter to manage an SNMP v3 node:

1. From the client's Admin menu, select Node List.

   The Node List window is displayed.

   

2. In the Node List window, select New if defining a new node, or select the node and then Open to change an existing node.

   The Node Definition window appears.

3. Select the SNMP tab.

   

4. Select the new protocol from the Authentication Protocol list box.
5. Select the Save button.

   A message box informs you that polling will be stopped for the node during this change and prompts you to confirm the operation.

6. Select Yes to proceed with the protocol change or No to cancel the operation.

      You can also change the protocol for one or more nodes from the Node List window. Right-click one or more nodes, select Authentication, and then select the protocol you want for the nodes.
   
   Polling will be halted for all selected nodes during this change.
