How to Configure DA Discovery for Dial-up Networks

You can use the following procedure to reduce unsolicited DA advertisements and active discovery by increasing the DA heartbeat period and the active discovery interval.

1. Become superuser.

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

   # /etc/init.d/slpd stop

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

4. Increase the net.slp.DAHeartbeat property in the slpd.conf file.

   net.slp.DAHeartbeat=value

   value

   A 32-bit integer that sets the number of seconds for the passive DA advertisement heartbeat  Default Value=10800 seconds (3 hours)  Range of Values=2000-259200000 seconds

   For example, you can set the DA heartbeat to approximately 18 hours on a host that is executing a DA:

   net.slp.DAHeartbeat=65535

5. Increase the net.slp.DAActiveDiscoveryInterval property in the slpd.conf file:

   net.slp.DAActiveDiscoveryInterval value

   value

   A 32-bit integer that sets the number of seconds for DA active discovery queries  Default Value=900 seconds (15 minutes)  Range of Values=300-10800 seconds

   For example, you can set the DA active discovery interval to 18 hours on a host that is executing a UA and an SA :

   net.slp.DAActiveDiscoveryInterval=65535

6. Save your changes and close the file.

7. Restart slpd to activate your changes.

   # /etc/init.d/slpd start
