Sample log messages
Table 11.3 shows sample log messages to give you an idea of how the
Syslog utility tracks events that are specific to the BIG-IP.
Powering down the BIG-IP
If you want to power down, or turn off, the BIG-IP you need to complete
two tasks. The first task is to shut down the BIG-IP software. After you shut
down the BIG-IP software, you can turn the power to the system off.

To complete the first task to shut down the BIG-IP software, type the
following command:
halt
After the system halts, you can turn the power to the system off.
Removing and returning items to service
Once you have completed the initial configuration on the BIG-IP, you may
want to temporarily remove specific items from service for maintenance
purposes. For example, if a specific network server needs to be upgraded,
you may want to disable the nodes associated with that server, and then
enable them once you finish installing the new hardware and bring the
server back online.
If you specifically disable the nodes associated with the server, the BIG-IP
allows the node to go down only after all the current connections are
complete. During this time, the BIG-IP does not attempt to send new
connections to the node. Although the BIG-IP monitoring features would
