9 SHM configuration examples
The following information provides SHM configuration examples for you to evaluate the network service,
and locate indexes that affect the network service.
Evaluating network service configuration example
Network requirements
As shown in Figure 23 , it takes users a long time to log in to the VPN gateway and access the internal
servers. The pre-analysis shows the problems occur on the VPN gateway and the core router. To identify
the critical factor that affects the network service, configure an SHM SLA to monitor those devices and
the link between them.

Requirement analysis
The main factors that can cause poor network services include the following items:
• Performance of the link between the VPN gateway and the core router, such as jitter, one-way
average delay, and unreachable rate.
• Response time and unreachable rate of the VPN gateway and the core router.
To identify the critical factor that affects the network service, you can configure an SLA as described
in
Table 17 that monitors and measures the KQI on the target objects.
