Precautions

Precautions

License Support

The SLA resource management scale is controlled by the license item "eSight Network SLA Management License (Device)". The number for the trial version is 10, and the max number is 5000. Each resource device managed by the SLA requires a license.

Component Dependency

The SLA management depends on the SLA&QoS management component.

Protocol Support

SNMP write parameters need to be set on the device and in the NMS system.

Device Support

Huawei devices that support the NQA function:

  • AR500, AR150, AR160, AR200, AR1200, AR2200, AR3200
  • NE16E, NE20, NE20E, NE40, NE40E, NE80, NE80E
  • S23, S27, S33, S37, S53, S57, S63, S67, S77, S93, S97, S127
  • CE5800, CE6800, CE7800, CE12800

For details about the model and version, see the specification list.

The device periodic task supports Huawei devices only.

The batch creation function applies to Huawei devices only.

Version Support

The SLA batch creation function is supported in V300R008C00 and later versions.

Application Scenario

The SLA periodically monitors the service quality and performance on a network to provide quantified network quality data for network maintenance engineers, and the quick diagnosis function enables users to effectively diagnose faults.

Feature Limitation and Dependency

  • The 30-second periodic task of the SLA supports a maximum of 30 test cases.
  • The function of importing SLA tasks in batches supports only ICMP Echo, ICMP Jitter, UDP Echo, and UDP Jitter test cases. A maximum of 500 or 1000 tasks can be imported at a time. (For details, see the information on the page.)
  • The function of exporting SLA tasks in batches supports only ICMP Echo, ICMP Jitter, UDP Echo, and UDP Jitter test cases. For tasks of other test cases, only basic task information can be exported. Specific test case parameters cannot be exported.
  • Northbound data can only be used in ICMP Echo test cases.
  • The corresponding service must be enabled on target devices of the SLA task. For example, the UDP service must be enabled on target devices of the UDP Echo test cases.
  • After a device periodic task is created, the periodic test cases will not be deleted from devices when the NMS is uninstalled.
  • After a device periodic task is created, the task configuration cannot be deleted or modified on the device. Otherwise, the eSight task will be abnormal.
  • If you create a large number of test cases on one device, the number of simulated packets will be excessively large. As a result, the device performance is affected, or the result is incorrect. Ensure that the number of test cases created on one device does not exceed the maximum number. The recommended number is 30. The maximum number can be obtained from the device document.
  • To enable the SLA to support link color change after alarm generation, you need to select only services containing one test case during SLA task creation and ensure that the source device, source port, and destination IP address of the task are consistent with the link parameters in the link management center.
