• On-demand system hardware diagnostics—Run on demand through user CLI commands; runs in
either of two modes: normal (faster-running basic test sequence) or extended (more thorough, but
longer-running test sequence).
The extended diagnostics include the packet memory scan, which checks the packet memory area of
the switch fabric for defects and maps out defective blocks. This test can be run by itself, as part of
the slot-based extended diagnostics, or can be invoked from within the system health checks.
• Switch-wide communication-path packet error health checks—(Apply only to "i" series Summit,
Alpine, and BlackDiamond switches.) An integrated diagnostic subsystem—the system health check
feature—that consists of a number of different test types, operating proactively in the background to
detect and respond to packet error problems in module memory or on communication paths.
The system health checks for "i" series switches include the following kinds of tests:
— Backplane health checks
— CPU health checks
— Switch fabric checksum validation
— Dynamic memory scanning and memory mapping
— Transceiver diagnostics
— Forwarding database (FDB) scan
NOTE
One component of the system health check feature is a bus monitoring and data integrity verification
subsystem that monitors the operation of all data and control busses within the switch. This low-level
subsystem—composed of software and hardware components—passes the results of its tests to
another system health check subsystem, an intelligent layer that is responsible for interpreting the
test results and reporting them to the user. Since the inception of the use of this intelligent
interpretation and reporting layer in the system health check feature, the operation of this
interpretation and reporting subsystem has undergone significant changes. At its current level of
maturity, it represents an intelligent, integral component of the overall system health check system.

Supported Hardware

The ExtremeWare diagnostic suite applies only to Extreme Networks switch products based on the
"inferno" series chipset. Equipment based on this chipset are referred to as being "inferno" series or "i"
series products: the BlackDiamond family of core chassis switches (6804, 6808, and 6816), the Alpine
systems (3802, 3804, 3808), and the Summit "i"-series stackables (Summit1i, Summit5i, Summit7i,
Summit 48i, and Summit48Si).
A subset of the ExtremeWare diagnostic suite—runtime, slot-based diagnostics—applies only to Extreme
Networks Summit "e" series switch products. The Summit "e" series switches include the following
models: Summit 200-24, Summit 200-48, Summit 300-24, Summit 300-48, Summit 400-24p,
Summit 400-24t, and Summit 400-48t.
