Configuring NQA to Check a Layer 2 Network

Configuring NQA to Check a Layer 2 Network

Before configuring network quality analysis (NQA) to check a Layer 2 network, familiarize yourself with the usage scenario and complete the pre-configuration tasks.

Usage Scenario

Table 4-4  Usage scenario for checking a Layer 2 network using NQA
Test Type Usage Scenario
MAC ping test MAC ping can test the connectivity, packet loss, and delay of links between devices on a Layer 2 network, facilitating fault locating.

Pre-configuration Tasks

Before configuring NQA to check a Layer 2 network, complete the following tasks:

  • Complete basic configurations of the Layer 2 network.

Configuration Procedures

Perform one or more of the following configurations as required.

Configuring a MAC Ping Test

MAC ping can test the connectivity, packet loss, and delay of links between devices on a Layer 2 network, facilitating fault locating.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Create an NQA test instance and specify the test instance type as MAC ping.
    1. Run:

      nqa test-instance admin-name test-name

      An NQA test instance is created, and the view of the test instance is displayed.

    2. Run:

      test-type macping

      The NQA test instance type is set to MAC ping.

    3. Run:

      description description

      A description is configured for the NQA test instance.

  3. Configure the MEP ID, MD name, and MA name based on the MAC ping type.
    1. Run:

      mep mep-id mep-id

      The local MEP ID is configured.

    2. Run:

      md md-name ma ma-name

      The names of the MD and MA for sending NQA test packets are configured.

  4. Perform either of the following steps to configure the destination address for the MAC ping test:

    • Run:

      destination-address mac mac-address

      The destination MAC address is configured.

      NOTE:
      To query a destination MAC address, run the display cfm remote-mep command.
    • Run:

      destination-address remote-mep mep-id remote-mep

      The peer MEP ID is configured.

    NOTE:
    If the destination address type is remote-mep, you must configure the mapping between the remote MEP and MAC address first.

  5. (Optional) Set optional parameters for the NQA test instance and simulate packets transmitted on an actual network.
    1. Run:

      datasize size

      The size of the data field in an NQA test packet.

      Only supported when the icmp-jitter-mode is icmp-echo.

    2. Run:

      probe-count number

      The number of probes in a test is set for the NQA test instance.

    3. Run:

      interval seconds interval

      The interval at which NQA test packets are sent is set for the NQA test instance.

  6. (Optional) Configure detection failure conditions and enable the function to send traps to the NMS upon detection failures.
    1. Run:

      timeout time

      The response timeout period is set.

      If no response packets are received before the set period expires, the probe is regarded as a failure.

    2. Run:

      fail-percent percent

      The failure percentage is set for the NQA test instance.

      If the percentage of failed probes is equal to or greater than the failure percentage, the test is regarded as a failure.

    3. Run:

      probe-failtimes

      The system is enabled to send traps to the NMS after the number of consecutive probe failures reaches the specified threshold.

    4. Run:

      test-failtimes times

      The system is enabled to send traps to the NMS after the number of consecutive failures of the NQA test instance reaches the specified threshold.

    5. Run:

      threshold rtd rtd-value

      The RTD threshold is configured.

    6. Run:

      send-trap { all | [ rtd | testfailure | probefailure | testcomplete ]* }

      The condition for triggering a trap is configured.

    7. Run:

      jitter-packetnum number

      The number of test packets to be sent during each test is set.

  7. (Optional) Configure the NQA statistics function.

    Run:

    records { history number | result number }

    The maximum number of history records and the maximum number of result records that can be saved for the NQA test instance are set.

  8. (Optional) Run:

    agetime hh:mm:ss

    The aging time for the NQA test instance is set.

  9. Schedule the NQA test instance.
    1. (Optional) Run:

      frequency interval

      The test period is set for the NQA test instance.

    2. Run:

      start

      An NQA test is started.

      The start command has multiple formats. Choose one of the following as needed.

      • To start an NQA test immediately, run the start now [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } } ] command.

      • To start an NQA test instance at a specified time, run the start at [ yyyy/mm/dd ] hh:mm:ss [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } } ] command.

      • To start an NQA test instance after a specified delay, run the start delay { seconds second | hh:mm:ss } [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } } ] command.

      • To start an NQA test instance at a specified time every day, run the start daily hh:mm:ss to hh:mm:ss [ begin yyyy/mm/dd ] [ end yyyy/mm/dd ] command.

  10. Run:

    commit

    The configuration is committed.

Checking the Configurations

After the test is complete, check the test results.

Prerequisites

NOTE:
NQA test results are not displayed automatically on the terminal. To view test results, run the display nqa results command.

Procedure

  • Run the display nqa results [ collection ] [ test-instance admin-name test-name ] command to check NQA test results.

Example

Run the display nqa results command to check the NQA test results.
