Configuring the MCP

Configuring the MCP

The MCP is the controller in the IP FPM system. It collects, summarizes, and calculates performance statistics, and reports measurement results to user terminals or the NMS.

Context

Figure 4-9 shows a typical networking for IP FPM end-to-end performance measurement. The target flow enters the transit network through RouterA, travels through RouterB, and leaves the transit network through RouterC. To monitor the transit network performance in real time or check whether a fault occurs on the transit network, configure IP FPM end-to-end performance measurement on RouterA and RouterC.
Figure 4-9  Networking diagram for IP FPM end-to-end performance measurement

In Figure 4-9, RouterA is configured as the MCP to collect performance statistics reported by DCP1 and DCP3, summarize and calculate the statistics, and report measurement results to user terminals or the NMS.

Perform the following operations on RouterA to configure it as the MCP.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run nqa ipfpm mcp

    The MCP function is enabled globally, and the IPFPM-MCP view is displayed.

    By default, the MCP function is disabled globally.

  3. Run mcp id mcp-id

    An MCP ID is configured.

    By default, an MCP has no ID. It is recommended that you use the Router ID of the device as the MCP ID.

    The MCP ID must be an IP address reachable to DCPs. The MCP ID must be the same as those specified in the IP FPM instances associated with DCPs using the mcp mcp-id [ port port-number ] command. If you change the MCP ID, you must also change the MCP IDs specified in the IP FPM instances associated with the DCPs. Otherwise, DCPs cannot communicate with the MCP.

  4. (Optional) Run protocol udp port port-number

    A UDP port number is specified on the MCP for the MCP to communicate with DCPs.

    The UDP port number specified on the MCP must be the same as those specified in the IP FPM instances associated with DCPs using the mcp mcp-id [ port port-number ] [ vpn-instance vpn-instance-name ] [ net-manager-vpn ] command. If you change the UDP port number on the MCP, you must also change the UDP port numbers specified in the IP FPM instances associated with the DCPs. Otherwise, DCPs cannot report statistics collected from TLPs to the MCP.

  5. (Optional) Run authentication-mode hmac-sha256 key-id key-id [ cipher ] password

    The authentication mode and password are configured on the MCP.

    By default, no authentication mode or password is configured on an MCP.

    You need to enable the authentication function when configuring IP FPM on networks that require high security. After the same authentication mode and password are configured on the MCP and DCPs, the MCP receives packets only from authenticated DCPs, improving network security and reliability of network performance measurement.

    The authentication mode and password configured on an MCP must be the same as those configured for all DCPs associated with the MCP using the authentication-mode hmac-sha256 key-id key-id [ cipher ] password command. Otherwise, the MCP cannot receive statistics reported by the DCPs.

  6. Run instance instance-id

    An IP FPM instance is created, and the instance view is displayed.

    By default, no IP FPM instance is created.

    In the IP FPM system, the IP FPM instance ID specified by the instance-id parameter must be unique in the management domain of the MCP to which the instance belongs. You must configure the same IP FPM instance on an MCP and all DCPs associated with the MCP simultaneously. Otherwise, IP FPM end-to-end performance measurement does not take effect.

    NOTE:

    After the configuration changes, you need to run the measure disable command to disable measurement of all indicators in a measurement instance on the MCP, and then run the measure enable command to enable measurement of all indicators in a measurement instance on the MCP. Otherwise, the statistics may fail to be collected.

    By default, measurement of all indicators is enabled in a measurement instance on the MCP.

    You are advised to enable packet loss measurement on the DCP and then enable measurement on the MCP.

  7. (Optional) Run authentication-mode hmac-sha256 key-id key-id [ cipher ] password

    The authentication mode and password are configured in the IP FPM instance.

    By default, no authentication mode or password is configured in an IP FPM instance.

    You need to enable the authentication function when configuring IP FPM on networks that require high security. After the same authentication mode and password are configured on the MCP and DCPs, the MCP receives packets only from authenticated DCPs, improving network security and reliability of network performance measurement.

  8. (Optional) Run description text

    A description is configured for the IP FPM instance.

    By default, no description is configured for an IP FPM instance.

    An IP FPM instance can be identified only by an ID in integer format. The description of an IP FPM instance helps you understand services and functions monitored by the instance and avoid misuses of the instance.

  9. Run dcp dcp-id

    A DCP ID is specified in the IP FPM instance.

    By default, no DCP ID is specified in an IP FPM instance on an MCP.

    The DCP ID in an IP FPM instance must be the same as those specified on DCPs using the dcp id dcp-id command. Otherwise, the MCP cannot receive statistics reported by the DCPs.
