To improve the performance of the Topology Split Manager, consider configuring the following parameters in the discovery.conf file to FALSE to disable their associated discovery probes:

  • STPTrunkEnabled (Default: TRUE) (not currently in discovery.conf)

  • HealthProbeEnabled (Default: TRUE) (not currently in discovery.conf)

  • IPv6DiscoveryEnabled (Default: TRUE)

  • HostResourcesEnabled (Default: TRUE)

  • VirtualRouterEnabled (Default: TRUE)

  • EnableF5PoolDiscovery (Default: TRUE) (not currently in discovery.conf)

    The STP probe, which is associated with STPTrunkEnabled, discovers Layer 2 connectivity by using spanning tree protocol information. If only a few connections in your network use STP, you should disable the STP probe to reduce memory consumption and discovery time.

    Also, consider configuring the following parameters in the discovery.conf file to TRUE to reduce the amount of SNMP information that is retrieved for network adapters and to enable SNMP get-bulk requests:

  • MinimumDemandGet (Default: FALSE)

  • SNMPGetBulkEnabled (Default: TRUE)

    To edit the discovery.conf file:

    1. Go to the TSM_BASEDIR/smarts/bin directory and enter the following command:

                           sm_edit conf/discovery/discovery.conf

    2. Locate the parameters that you want to change and change their values.

      For example:

      IPv6DiscoveryEnabled = FALSE

    3. Save and close the file.

      The modified version of the discovery.conf file is saved to the TSM_BASEDIR/smarts/local/conf/discovery directory.

    4. If the Topology Split Manager was running before you edited the discovery.conf file, either restart the Topology Split Manager or invoke the following dmctl command:

                           sm_tpmgr -s <TSM name> --load-conf=discovery.conf
