ANTA Tests for hardware
Tests¶
Module related to the hardware or environment tests.
VerifyAdverseDrops ¶
Verifies there are no adverse drops exceeding defined thresholds.
Compatible with Arista 7280R, 7500R, 7800R and 7700R series platforms supporting hardware counters.
Note
The ReassemblyErrors
counter on a FAP can increment as a direct symptom of FCS errors
on one of its ingress
interfaces. This test can be configured to not fail on ReassemblyErrors
if this correlation is found, treating
them as an expected side effect of the initial FCS errors.
Expected Results
- Success: The test will pass if all adverse drop counters are within their defined thresholds.
- Failure: The test will fail if any adverse drop counter exceeds its threshold.
Examples
anta.tests.hardware:
- VerifyAdverseDrops:
thresholds: # Optional
minute = 3
ten_minute = 20
hour = 100
day = 500
week = 1000
always_fail_on_reassembly_errors: false
