Understanding SAID

Understanding SAID


An SAID node is a function node that is used by the SAID system to perform fault detection, diagnosis, and correction. SAID nodes are classified into two types:
  • Diagnostic SAID node: With this type of node, the SAID system only determines whether the device is faulty based on the collected data, without rectifying the fault if the device is faulty.
  • Self-healing SAID node: With this type of node, the SAID system determines whether the device is faulty based on the collected data and automatically rectifies the fault if the device is faulty.
Currently, the switch supports the following SAID nodes listed in Table 11-1.

SAID Detection Process

After the device completes the startup, the SAID system periodically performs fault detection. The process consists of the following tasks:
  1. Data collection: The SAID system periodically collects detection data based on the detection period registered by an SAID node.
  2. Data diagnosis: The SAID system sends the collected detection data to the service module for diagnosis. If the data is incorrect, the system processes the data based on the SAID node type.
  3. Troubleshooting: If the SAID node is a diagnostic node, the SAID system only records a log or reports an alarm, without performing self-healing. If the SAID node is a self-healing node, the SAID system instructs the service module to perform fault self-healing. After self-healing is complete, the SAID system records a log indicating that self-healing is complete.
