# Create SNMP proxies

Before you begin

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

Note: You cannot use the WebLogic SNMP agent to proxy requests to other WebLogic 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.

Instead of using one WebLogic Server domain to proxy requests to other domains, you can place all of your server instances in a single domain. SNMP managers can request monitoring data directly from each Managed Server within the domain.

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

To configure the 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, expand Diagnostics > SNMP Agent and select Proxies.
3. On the SNMP Proxies page, click New.
4. On the Create an SNMP Proxy page, enter a name for the SNMP agent (proxy) that will receive requests.
5. 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.

6. Click OK.
7. On the SNMP Proxies page, click the name of the new proxy.
8. On the SNMP Proxies: General page:
   1. In Port, enter the port number on which the proxy is listening.
   2. Modify default values for the other attributes. See Configuration Options or More Info.
9. 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).

After you finish

Restart the Administration Server.
