Juniper SRX Series

Chapter 5. System Services

To best leverage the SRX platforms, you need to have a solid understanding of both the security concepts and components, but also of the platform itself. Junos provides a very rich set of features when it comes to system services. Properly configuring and operating the system services is often overlooked during the initial setup of the system. Although most of these topics are the same as other Junos platforms, such as the EX/M/MX/T Series, there are some different implications with the SRX because it is a security device, and some of the security and hardware components rely on these differently. In this chapter, we examine the various system services that you should be aware of on the platform and how to properly leverage them to get the best operational state.

System Services Operation on the SRX

Before we delve into how to configure the individual components in the Junos system services family, we will first have a quick discussion of how the system services operate in the SRX itself so that you have a good understanding of how the system functions operationally. With the proper background, you will have the tools you need to effectively configure and operate the SRX.

Figure 5-1 shows a high-level view of where system services live on the SRX. This is true for both the branch and the high-end SRX because there is a true separation of the control and data plane—even if it is just processor/memory separation on the branch SRX.
