1.2.1.4 Diagnostics
The following diagnostics are available for the switch:
1. In-service Diagnostics – In-service diagnostics provide a range of automatic health monitoring features
ensuring both the system hardware and software are in working order. The in-service-diagnostics
continuously monitor any available physical characteristics (as detailed below) and issues log messages
when either warning or error thresholds are reached. There are three types of in-service diagnostics:
• Hardware– Ethernet ports, chip failures, system temperature via the temperature sensors provided
by the hardware, etc.
• Software– CPU load, memory usage, etc.
• Environmental– CPU and air temperature, fans speed, etc.
2. Out-of-service Diagnostics – Out-of-service diagnostics are a set of intrusive tests run from the user
interface. Out-of-service diagnostics cannot be run while the unit is in operation. The intrusive tests
include:
• Ethernet loopback tests
