To enable and disable nodes and node addresses from the
command line
The bigpipe node command allows you to enable or disable individual
nodes, as well as node addresses.
To enable or disable a node, type the appropriate command:
b node <node addr>:<node port> enable
b node <node addr>:<node port> disable
To enable or disable a node address, type the appropriate command:
b node <node addr> enable
b node <node addr> disable
Viewing the currently defined virtual servers and nodes
When used with the show parameter, bigpipe commands typically display
currently configured elements. For example, the bigpipe virtual show
command displays all currently defined virtual servers, and the bigpipe
node command displays all nodes currently included in virtual server
mappings. For additional information about using bigpipe commands on the
BIG-IP, see Chapter 7, bigpipe Command Reference.
Viewing system statistics and log files
The Configuration utility allows you to view a variety of system statistics
and system log files. Note that from each statistics screen, you can access
property settings for individual virtual servers, nodes, IP addresses, and
ports by selecting the individual item in the statistics table.
Viewing system statistics
The Configuration utility allows you to view the following statistical
information:
• BIG-IP system statistics, including the elapsed time since the last system
reboot, the number of packets and connections handled by the system,
and the number of dropped connections
• Virtual servers, including virtual servers, virtual address only, or virtual
ports only
• Nodes, including nodes, node addresses only, or node ports only
• NAT statistics, such as the number of packets handled by each NAT
• SNAT statistics, such as SNAT mappings
• IP filter statistics, including the number of packets accepted and rejected
by individual IP filters
