Setup RPM

Problem

Description: You are here: Troubleshoot>RPM>Setup RPM.

You can configure RPM parameters to monitor real-time performance through the J-Web interface. You can specify a RPM owner, request information related to probe, hardware timestamp, generates Traps, and specify a probe server.

Solution

To configure RPM parameters:

Procedure

  1. Enter the information specified in Table 321 to troubleshoot the issue.
  2. From the main RPM configuration page, click one:
    • Apply—Applies the configuration and stays on the RPM configuration page.

    • OK—Applies the configuration and returns to the RPM configuration page.

    • Cancel—Cancels your entries and returns to the RPM configuration page.

Field

Function

Probe Owners
Identification

Owner Name

Specifies an RPM owner for which one or more RPM tests are configured. In most implementations, the owner name identifies a network on which a set of tests is being run (a particular customer, for example).

Type the name of the RPM owner.

Identification

Test name

Specifies a unique name to identify the RPM test.

Type the name of the RPM test.

Specifies an IP address or a URL of a probe target.

Type the IP address, in dotted decimal notation, or the URL of the probe target. If the target is a URL, type a fully formed URL that includes http://.

Source Address

Specifies an IP address to be used as the probe source address.

Type the source address to be used for the probe. If the source IP address is not one of the device's assigned addresses, the packet uses the outgoing interface's address as its source.

Specifies the size of the data portion of the ICMP probes.

Type a size (in bytes) between 0 and 65507.

Specifies the contents of the data portion of the ICMP probes.

Type a hexadecimal value between 1 and 800h to use as the contents of the ICMP probe data.

Hardware Timestamp

One Way Hardware Timestamp

Specifies the hardware timestamps for one-way measurements.

To enable one-way timestamping, select the check box.

Hardware Timestamp

Specifies timestamping of RPM probe messages. You can timestamp the following RPM probes to improve the measurement of latency or jitter:

  • ICMP ping

  • ICMP ping timestamp

  • UDP ping—destination port UDP-ECHO (port 7) only

  • UDP ping timestamp—destination port UDP-ECHO (port 7) only

To enable timestamping, select the check box.

Specifies the name of an output interface for probes.

Select the interface from the list.
