Troubleshooting Commands
run diagnostics packet-memory slot
run diagnostics packet-memory slot <slot number>
Description
Executes packet memory scanning for all packet memory associated with the specified I/O slot on a
BlackDiamond 6808 or 6816.
Syntax Description
Default
N/A.
Usage Guidelines
If you run the diagnostic routine on an I/O 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 I/O 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 blade, module, or stackable to detect single bit-related
memory defects and their associated buffer locations. If packet memory defects are detected, their
locations are recorded in the blade’s 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 I/O 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
sys-health-check
is configured for
online
. The module should then be returned through the RMA
process with Extreme Networks Technical Support.
When you enter the run diagnostic command, you are warned about any potential impacts on your
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.
To show the results of a packet-memory diagnostic, use the following command:
show diagnostics packet-memory slot <slot number>
Example
The following command runs a packet-memory scan on the board in slot 4 on a BlackDiamond:
run diagnostics packet-memory slot 4
slot number Specifies the slot number of an I/O module. This option is available only on
BlackDiamond switches. In v 6.2.1, cannot specify an MSM. In v 6.2.2 this
option is available on “i” series, stackables, and Alpine.
