gNMI-1.5: Telemetry: Port Speed Test

Summary

Validate port speed telemetry used by controller infrastructure.

Procedure

• For each port speed to be supported by the device:
  • Connect single port to ATE, validate that the port speed reported in telemetry is the expected port speed.
  • Turn port down at ATE, validate that operational status of the port is reported as down.
• For each port speed to be supported by the device:
  • Connect N ports between ATE and DUT configured as part of a LACP bundle. Validate /interfaces/interface/aggregation/state/lag-speed is reported as N*port speed.
  • Disable each port at ATE and determine that the effective speed is reduced by the expected amount.
  • Turn ports sequentially up at the ATE, and determine that the effective speed is increased as expected.
