SOL8035: Overview of BIG-IP daemons on Version 9 Updated: 2/27/08 4:50 PM

The BIG-IP system daemons perform a variety of functions, such as managing load-balanced traffic, configuring and controlling the switch chips, monitoring the health and performance of pool members, and performing high availability failover actions.

BIG-IP services belong to one of two categories: core daemons, which start up when you boot the BIG-IP system and run continually, and secondary daemons, which are not critical for basic operation. The tasks required to manage these daemons is different depending on whether the daemon is a core or an optional daemon.  Core BIG-IP daemons 

Core BIG-IP daemons are those that are  essential to system operation.  The following table lists the core BIG-IP services, and indicates the impact to BIG-IP system operation if the service is not running:

For example, to view the status of the  bcm56xxd service, type the following command:  bigstart status bcm56xxd  For information about using the bigstart utility, see the bigstart man page.
