The passiveDADetection option is True by default. Directory agents will periodically broadcast
their existence on the subnet on a well-known port if configured to do so. These packets are termed
DAAdvert packets. If this option is set to
False , all broadcast DAAdvert packets are ignored by the
SA.
The
activeDADetection option is also True by default. This allows the SA to periodically broadcast
a request for all DAs to respond with a directed DAAdvert packet. A directed packet is not broadcast,
but sent directly to the SA in response to these requests. If this option is set to
False , no periodic DA
discovery request is broadcast by the SA.
The
DAActiveDiscoveryInterval option is a try-state parameter. The default value is 1 , which is a
special value meaning that the SA should only send out one DA discovery request upon
initialization. Setting this option to
0 has the same effect as setting the activeDADetection option to
false . Any other value is a number of seconds between discovery broadcasts.
These options, when used properly, can ensure an appropriate use of network bandwidth for service
advertising. In fact, the default settings are designed to optimize scalability on an average network.
