RPM Thresholds and Traps

You can configure RPM threshold values for the round-trip times, ingress (inbound) times, and egress (outbound) times that are measured for each probe, as well as for the standard deviation and jitter values that are measured for each test. Additionally, you can configure threshold values for the number of successive lost probes within a test and the total number of lost probes within a test.

If the result of a probe or test exceeds any threshold, the Services Router generates a system log message and sends any Simple Network Management Protocol (SNMP) notifications (traps) that you have configured.

RPM for BGP Monitoring

When managing peering networks that are connected using Border Gateway Protocol (BGP), you might need to find out if a path exists between the Services Router and its configured BGP neighbors. You can ping each BGP neighbor manually to determine the connection status, but this method is not practical when the Services Router has a large number of BGP neighbors configured.

In the Services Router, you can configure RPM probes to monitor the BGP neighbors and determine if they are active.

For BGP configuration information, see the J-series Services Router Basic LAN and

WAN Access Configuration Guide.

Before You Begin

Before you begin configuring RPM, complete the following tasks:

■Establish basic connectivity. See the Getting Started Guide for your router.

■Configure network interfaces. See the J-series Services Router Basic LAN and WAN Access Configuration Guide.

■Configure SNMP. See “Configuring SNMP for Network Management” on page 47.

Configuring RPM with Quick Configuration

J-Web Quick Configuration allows you to configure real-time performance monitoring (RPM) parameters. Figure 26 on page 272 shows the main Quick Configuration page for RPM. Figure 27 on page 272 shows the probe test Quick Configuration page for RPM.
