SNMP Access Control in High Availability (HA) Environments

When NNMi is configured in a High Availability (HA) environment, the SNMP source address is set to a physical cluster node address. To set the SNMP source address to the NNM_INTERFACE (which is set to the virtual IP address), you must edit the ov.conf file and set the value for IGNORE_NNM_IF_FOR_SNMP to OFF. (By default, this setting is set to ON.)

To set the SNMP source address to the NNM_INTERFACE in HA environments:

  1. Edit the following file on both nodes in the cluster:

    Windows: %NnmDataDir%\shared\nnm\conf\ov.conf

    Linux: $NnmDataDir/shared/nnm/conf/ov.conf

  2. Set the value for IGNORE_NNM_IF_FOR_SNMP to OFF. (By default, this setting is set to ON.)

    IGNORE_NNM_IF_FOR_SNMP=OFF

  3. Stop and restart the NNMi management server:

    Note Put the nodes in maintenance mode before running the ovstop and ovstart commands

    1. Run the ovstop command on the NNMi management server.
    2. Run the ovstart command on the NNMi management server.
