Overview of the ExtremeWare Diagnostics Suite

The ExtremeWare diagnostic suite includes the following types of tools for use in detecting, isolating,
and treating faults in a switch. Each of these diagnostic types is summarized below, but is described in
greater detail in later sections of this guide.
• Power-on self test (POST)—A sequence of hardware tests that run automatically each time the switch
is booted, to validate basic system integrity. The POST runs in either of two modes: normal (more
thorough, but longer-running test sequence) or FastPOST (faster-running basic test sequence).
• 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—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 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

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).

Applicable ExtremeWare Versions

The information in this guide is based on the features and feature attributes found in
ExtremeWare Version 6.2.2b134 or later.
