Create SNMP proxies

Before you begin

Create a WebLogic Server SNMP agent (see Create SNMP agents ) and configure other, non-WebLogic Server, SNMP agents to run on the same computer as the WebLogic Server SNMP agent.

Note: You cannot use a WebLogic Server SNMP agent to proxy requests to other WebLogic Server SNMP agents. For example, WebLogic domainA's SNMP agent cannot proxy requests to domainB's SNMP agent. This limitation is in effect because all WebLogic SNMP agents use the same MIB root.


WebLogic Server SNMP agents can forward (proxy) requests from SNMP managers to other SNMP agents that reside on the agent's host computer. WebLogic Server proxies only the requests with object identifiers (OIDs) that are under a specific the OID root. For more information, see SNMP Proxies .

To configure a WebLogic Server SNMP agent to forward requests from SNMP managers to another SNMP agent:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the Administration Console, under Domain Structure , expand Diagnostics and select SNMP .
  3. On the Summary of SNMP Agents page, in the Server SNMP Agents table, click the name of an SNMP agent.
  4. On the SNMP Agent: Configuration: General page, click the Proxies sub-tab.
  5. On the SNMP Proxies page, click New .
  6. On the Create an SNMP Proxy page, enter a name to identify the proxy.
  7. In OID Root , enter the root of the OID tree that the proxy controls.

    WebLogic Server forwards to the proxy only the requests that are in this OID tree.

  8. In Port , enter the port number on which the proxied agent is listening.
  9. If you want this WebLogic SNMP agent to use SNMPv3 when communicating with this proxy:
    1. In Security Name, enter the user name on whose behalf the WebLogic SNMP agent forwards requests.

      The user name must be the name of an existing WebLogic Server user for whom you have created an SNMP credential map. When the WebLogic SNMP agent prepares the request that it will forward to the proxy, it uses the credential map to look up and encode SNMP credentials. For information about creating an SNMP credential map, see Secure SNMPv3 communication.

    2. In the Security Level list, select a security level that is equal to or lower than the security level that is configured for communication between the WebLogic SNMP agent and SNMP managers.

      For example, if the WebLogic SNMP agent requires incoming SNMPv3 requests to use the authentication protocol but no privacy protocol, the security level for this proxy must be either Authentication Only or None.

  10. If you want this WebLogic SNMP agent to use SNMPv1 when communicating with this proxy, do not enter a value for Security Name. Instead, in Community, enter the community name that the proxy requires for incoming requests.

    For information about providing a community name, see the description of Community in Configuration Options.

    Note: WebLogic SNMP agents cannot be configured to use SNMPv2 to communicate with proxies.

  11. Click OK .
  12. On the SNMP Proxies page, click the name of the new proxy.
  13. On the SNMP Proxies: General page, modify default values for the other attributes. See Configuration Options or More Info .
  14. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).
