System Impact Of Running The Diagnostics On "I" Series Switches; Runtime Diagnostics On "E" Series Systems - Extreme Networks ExtremeWare Version 7.8 Troubleshooting Manual

System Impact of Running the Diagnostics on " i " Series Switches
These diagnostics are invasive diagnostics. The diagnostics perform different tests, depending on
whether the test is being performed on the CPU subsystem or an individual I/O module. The
diagnostics reset and erase all current hardware states. The impact of the diagnostics depends on the
switch type and—in the case of the BlackDiamond switch—whether the module type being tested is an
MSM or an I/O module (see

NOTE
When you run the packet memory diagnostic, the system displays a message warning about potential
impacts on your switch and network (because the module—in a BlackDiamond switch—or the entire
switch—for Alpine and Summit switches—will be taken offline during the time the diagnostic is running)
and prompts you to confirm or cancel the test.
When you enter the
Alpine, or a Summit system, the system displays the following message and prompts you to confirm
the action:
Running Normal diagnostics will reset the switch and disrupt network traffic.
Are you sure you want to continue?
When you enter the
Alpine, or a Summit system, the system displays the following message and prompts you to confirm
the action:
Running Extended diagnostics will reset the switch and disrupt network traffic.
Extended diagnostic will also execute Packet Memory Scan........
WARNING: Device may be taken offline. To prevent this
first configure "sys-health-check alarm-level auto-recovery online"
Are you sure you want to continue?
Runtime Diagnostics on " e " Series Systems
The ExtremeWare diagnostics tests for the "e" series switches is a set of one-time test routines that can
be run on demand by user command. These tests check the CPU subsystem, the switch fabric
subsystem, and control and data path communication.
