System Health Checking
The BlackDiamond 10808 supports extensive error-checking and monitoring capabilities. Packet and
system memories are protected by an error correction code (ECC). ECC is capable of correcting all
single-bit errors and detecting all other memory errors. The data path is protected by check sums and
parity checks. The system automatically corrects correctable memory errors and kills packets that
encounter check sum and parity errors during processing. Errored packets are not propagated through
the system.
The primary responsibility of the system health checker is to monitor and poll the ASIC error registers.
The system health checker processes, tracks, and reads the memory, parity, and check sum error counts.
The ASICs maintain counts of correctable and uncorrectable memory errors, as well as packets that
encountered check sum and parity errors. In a running system, some of these error counts may show
non-zero values. Occasional increments of these counters does not mean faulty hardware is detected or
that hardware requires replacement. If you see persistent increments of these counters, please contact
Extreme Networks Technical Support.
In addition, the system health checker can be enabled to check the backplane, CPU, and I/O modules
by periodically sending diagnostic packets and checking the validity of the looped back diagnostic
packets.
In summary, two modes of health checking are available: polling and backplane diagnostic packets.
These methods are briefly described in the following:
