What is isisCircAuthFails?

Counts how many times an IS-IS control PDU with the correct authentication type has still failed authentication validation on this circuit, the per-circuit counterpart to isisSysStatAuthFails. An admin uses this to localize a credential (password/key) mismatch to a specific circuit rather than a type mismatch.

Examples
