Appendix A Online Diagnostic Tests Per-Port Tests TestScratchRegister The TestScratchRegister test monitors the health of application-specific integrated circuits (ASICs) by writing values into registers and reading back the values from these registers. The test runs every 30 seconds. Five consecutive failures causes a supervisor engine to switchover (or reset), if you are testing the supervisor engine, or in the module powering down when testing a module. Table A-3 TestScratchRegister Test Attributes Attribute Disruptive/Nondisruptive Recommendation Default Release Corrective action Hardware support Description Nondisruptive. Do not disable.

Per-Port Tests The per-port tests consist of the following tests: • TestNonDisruptiveLoopback, page A-3 • TestLoopback, page A-4 • TestActiveToStandbyLoopback, page A-4 • TestTransceiverIntegrity, page A-5 • TestNetflowInlineRewrite, page A-5 TestNonDisruptiveLoopback The TestNonDisruptiveLoopback test verifies the data path between the supervisor engine and the network ports of a module. In this test, a Layer2 packet is flooded onto VLAN that contains a group of test ports. The test port group consists of one port per port ASIC channel. Each port in the test port group nondisruptively loops back the packet and directs it back to the supervisor engine's inband port. The ports in the test port group are tested in parallel.
