NM Station Cannot Receive RMON Alarms

NM Station Cannot Receive RMON Alarms

Common Causes

This fault is commonly caused by one of the following:
  • There is no reachable route between the router and the NM station.

  • The SNMP alarm function is not configured correctly.

  • Rmon StatsTable is not configured.

  • The statistics of RMON is not enabled.

  • The RMON eventTable is not enabled.

  • The RMON alarmTable is not enabled.

  • The alarm variables are not configured correctly.

Troubleshooting Flowchart

When the traffic that flows in and out of the LAN exceeds the configured threshold, the NM station fails to receive alarms. Figure 14-7 shows the troubleshooting flowchart.

Troubleshooting Procedure

Context

NOTE:

Save the results of each troubleshooting step. If your troubleshooting fails to correct the fault, you will have a record of your actions to provide contact technical support personnel.

Procedure

  1. Check whether there are reachable routes between the router and the NM station.

    Ping the NM station interface from the router.
    • If the ping succeeds, it indicates that the routes between the router and the NM station are reachable, go to Step 2.
    • If the ping fails, check the routes between the router and the NM station. For details of routing troubleshooting, see the section The Ping Operation Fails.

  2. Check that the SNMP alarm function is configured correctly.

    Check whether the NM station can receive other alarms. If not, do as follows:

    • Run the display snmp-agent trap feature-name rmon all command to check whether the alarm function of the router is enabled

    • Run the display snmp-agent target-host command to check whether the NM address through which the router sends alarms is correct

  3. Check that the statistics of RMON is enabled.

    Run the display this command on the specified interface to check whether the statistics of RMON is enabled. If the statistics of RMON is disabled, run the rmon-statistics enable command.

  4. Check that rmonStatsTable is configured.

    Run the display rmon statistics command on the router to check whether rmonStatsTable is configured. If rmonStatsTable is null, run the rmon statistics entry-number [ owner owner-name ] command to create entries of the table.

  5. Check that the RMON eventTable is enabled.

    Run the display rmon event [ entry-number ] command on the router interface to check whether the RMON eventTable is enabled. If the eventTable is null, run the rmon event command to create entries of the table.

  6. Check that the RMON alarmTable is enabled.

    Run the display rmon alarm [ entry-number ] command on the router interface to check whether the RMON alarmTable is enabled. If the alarmTable is null, run the rmon alarm command to create entries of the table.

  7. Check that the alarm variables are configured correctly.

    Run the display rmon alarm [ entry-number ] command on the router interface to view the value of the configured alarm variables. On the NM station, check that the values of alarm variables of the interface are consistent with those values configured on the router interface. If the values are inconsistent, modify the values of the alarm variables to be consistent.

  8. After the preceding operations are complete, if the NM station cannot receive the alarm values of the RMON module on the router, contact technical support personnel.
