System Log Alerts for Packet Loss |
Release 24.1.1 |
You can quickly get notified about any traffic impacting errors within the router's Network Processing Unit (NPU). These notifications are error log messages on the router console for NPU interrupts that affect traffic. To diagnose traffic loss, follow the recommended actions in the log. Previously, the only way to identify NPU errors that impacted traffic was to run the show asic-error command. This feature introduces the following changes: CLI: This feature introduces the hw-module profile packet-loss-alert command. YANG Model: New xpaths for |
Network packet loss can significantly impact the overall experience of end-users, particularly when using real-time applications such as voice or video. Therefore, network administrators need to address such issues promptly to ensure the integrity of these services.
Now you can configure your router to provide immediate alerts in the event of packet loss, along with configuring the duration of packet loss to raise the alert. This feature enables network administrators to quickly identify the specific router within the network that is experiencing the problem. It facilitates a swift and precise response to rectify the issue and maintain optimal network performance.
