Global Health-Monitoring Tests
The global health monitoring tests consist of the following tests:
TestSPRPInbandPing, page A-2
TestMacNotification, page A-3
TestSPRPInbandPing
The TestSPRPIinbandPing test detects most runtime software driver and hardware problems on
supervisor engines by running diagnostic packet tests using the Layer 2 forwarding engine, the Layer 3
and 4 forwarding engine, and the replication engine on the path from the switch processor to the route
processor. Packets are sent at 15-second intervals. Ten consecutive failures of the test results in failover
to the redundant supervisor engine (default) or reload of the supervisor engine if a redundant supervisor
engine is not installed.
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.
