Configuring Telemetry on RoCE Networks
Telemetry is a technology for rapidly collecting data from remote devices. Devices proactively send their data to the collector in push mode, implementing real-time and high-speed data collection.
- The onsite network must be implemented based on the plan to ensure that all switches on the data center network and collectors can communicate with each other. Otherwise, Telemetry packets will fail to be reported. The Telemetry configuration on devices must be planned based on the network requirements. The configuration here is only for reference.
- For details about the version support and licensing requirements for Telemetry, see "Licensing Requirements and Limitations for Telemetry" in CloudEngine Series Switches Product Documentation.
