3.3.1 Configuring an SNMP proxy

Some networks use SNMP proxy agents to communicate with network devices. Figure 3-1 shows the SNMP communication procedure that NNMi uses when SNMP Proxy Address and SNMP Proxy Port are configured by using Configuration > Communication Configuration from the NNMi console. NNMi supports SNMP proxy servers that support SecurityPackAgentAddressOid OID (.1.3.6.1.4.1.99.12.45.1.1).

Figure 3‒1: Using proxy servers

[Figure]

  1. The NNMi management server sends an SNMP request to the SNMP proxy address and SNMP proxy port to obtain information from the managed router and switch. The NNMi management server uses the special proxy varbind SecurityPackAgentAddressOid OID (.1.3.6.1.4.1.99.12.45.1.1) to encode the remote address and port of the managed router and switch, and then adds this varbind to the SNMP request.

  2. The SNMP proxy server reads this special proxy varbind, determines the destination of the SNMP request, and then sends the SNMP request to the managed router and switch to obtain the information requested by the NNMi management server.

  3. The managed router and switch respond to the SNMP proxy server (using the SNMP proxy address and SNMP proxy port) and return the requested information.

  4. The SNMP proxy server responds to the NNMi management server (using the configured SNMP port).

    If NNMi is configured to use proxy servers, NNMi processes SNMP responses by using the following OIDs:

    • SecurityPackAgentAddressOid .1.3.6.1.4.1.99.12.45.1.1 (SNMP Research NetDiscover SECURITY-PACK-MIB)

    • SecurityPackNotificationAddressOid .1.3.6.1.4.1.99.12.45.2.1 (SNMP Research NetDiscover SECURITY-PACK-MIB)

    • ProxyOid .1.3.6.1.4.1.11.2.17.5.1.0 (HP)

    • TrapForwardingAddressTypeOid .1.3.6.1.4.1.11.2.17.2.19.1.1.2.0 (HP)

    • TrapForwardingAddressOid .1.3.6.1.4.1.11.2.17.2.19.1.1.3.0 (HP)

    • Rfc3584TrapAddressOid .1.3.6.1.6.3.18.1.3.0 (RFC 3584)

    • Rfc3584TrapCommunityOid .1.3.6.1.6.3.18.1.4.0 (RFC 3584)

    If you will be using NNMi on an SNMP proxy server, contact your proxy vendor to check which of the OIDs listed above are supported.
