gNMI-1.27: gNMI Sample Mode Test

Summary

Test to validate basic gNMI streaming telemetry works with SAMPLE mode.

Procedure

Test 1: Verify that correct SAMPLE Mode telemetry is streamed when Interface Description is updated

• Create a new gNMI Subscription to Interface description state leaf in SAMPLE mode. with a 10 second interval

• Configure Port-1 with description DUT Port 1.

• Verify correct description is streamed.

• Update Port-1 description to DUT Port 1 - Updated.

• Verify correct description is streamed.

Test 2: Verify that no invalid telemetry is streamed during state update

• Create a new gNMI Subscription to Interface description state leaf in SAMPLE mode with a 10 second interval.

• Configure Port-1 with description DUT Port 1.

• Flap port 1 interface and wait for it to be UP.

• Collect all the samples streamed and validate no invalid values were streamed during the flap.

Test 3: Verify SAMPLE Mode telemetry is eventually consistent

• Create a new gNMI Subscription to Default Network Instance state container in SAMPLE mode with a 10 second interval.

• Configure ISIS on Port 1 in Default Network Instance.

• Verify that ISIS telemetry is streamed within the next 5 samples.
