Description: Verifying Crossbar Existence.
What is bistCrossbarExistence?
This read-only object reports the pass or fail result of the BIST test verifying the existence and basic functionality of the device's switch fabric crossbar. Admins check it to rule out a fundamental switch-core hardware fault when diagnosing widespread forwarding problems across multiple ports. A failing bistCrossbarExistence result would point to a serious switch-fabric hardware problem likely affecting forwarding across the entire device, not just a single port.
