ProcedureHow to Configure the Random-Wait Bound

Use the following procedure to change the net.slp.RandomWaitBound property in the slp.conf file.

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  2. Stop slpd and all SLP activity on the host.

    # svcadm disable network/slp
  3. Back up the default /etc/inet/slp.conf file before you change the configuration settings.

  4. Change the net.slp.RandomWaitBound property in the slpd.conf file:


    The upper bound for calculating the random-wait time before attempting to contact a DA

    Default Value=1000 milliseconds (1 second)

    Range of Values=1000 to 3000 milliseconds

    For example, you can lengthen the maximum wait to 2000 milliseconds (2 seconds).


    When you lengthen the random-wait bound, a longer delay in registration occurs. SAs can complete registrations with newly discovered DAs more slowly to avoid collisions and timeouts.

  5. If necessary, change the net.slp.datagramTimeouts property in the slpd.conf file:


    A list of 32–bit integers that specify timeouts, in milliseconds, to implement unicast datagram transmission to DAs


    For example, you can increase the datagram timeout to 20000 milliseconds to avoid frequent timeouts.


    In high-performance networks, you can reduce the time-out bound for multicast and unicast UDP datagram transmission. This setting reduces the amount of latency in satisfying SLP requests.

  6. Save your changes and close the file.

  7. Restart slpd to activate your changes.

    # svcadm enable network/slp
