Services
BIG-IP® Reference Guide 4 - 119
Services
Services are the standard Internet applications supported by BIG-IP, such as
HTTP, HTTPs, FTP, and POP3. Each service is known by its name and
also by its well-known or reserved port number such as 80 or 443.
(Specifically, a service is any valid service name in the /etc/services file or
any valid port number between 0 and 65535.) The bigpipe service
command allows you to enable and disable network traffic on services, and
also set connection limits and timeouts. You can use the service name or the
port number for the <service> parameter. Note that the settings you define
with this command control the service for all virtual servers that use it. By
default, access to all services is disabled.
Tip
Virtual servers using the same service actually share a port on the BIG-IP.
This command is global, you only need to open access to a port once; you
do not need to open access to a port for each instance of a virtual server
that uses it.
Table 4.22 lists the attributes you can configure for a service.
To allow access to services using the Configuration utility
Any time you create a virtual server and define a port or service with the
Configuration utility, the port or service is automatically enabled.
To allow access to services from the command line
Using the bigpipe service command, you can allow access to one or more
services at a time.
b service <service>...<service> <protocol> [tcp|udp] enable
For example, in order to enable HTTP (service 80) and Telnet (service 23)
services, you can type the following bigpipe service command:
b service 80 23 443 tcp enable
Attributes Description
Allow access to services As a security measure, all services are locked down on the BIG-IP. In order for the
BIG-IP to load balance traffic, you must enable access to the service on which the
BIG-IP will receive traffic.
Connection limits You can define a connection limit for a service so that a flood of connections does not
overload the BIG-IP.
Set idle connection
timeouts
You can set the idle connection timeout to close idle connections.
