Usage Guidelines
If you run the diagnostic routine on a module, that module is taken off-line while the diagnostic test is
performed. The ports on the module do not forward traffic. Once the diagnostic test is completed, the
module is automatically reset and becomes operational again.
NOTE
Run diagnostics when the switch can be brought off-line. The tests conducted are extensive and affect
traffic that must be processed by the system CPU. The diagnostics are processed by the CPU whether
you run them on an I/O or a management module.
Packet memory scanning scans the specified module to detect single bit-related memory defects and
their associated buffer locations. If packet memory defects are detected, their locations are recorded in
the module EEPROM. Up to eight occurrences can be recorded. If a defect was found during the scan
process, the module is reset, the defective buffer is mapped out from further use, and the module is
returned to the operational state. If more than eight defects are detected, or if the defects cannot be
mapped out, the module is treated as a failed module and left offline, unless
configured for . The module should then be returned through the RMA process with Extreme
online

switch and network (since the module will be taken offline during the diagnostic process) and you will
have an opportunity to confirm or cancel the test.
