Write output
root@dell-diag-os:~# memtool --write --addr=200 --val=0x50
Constraints
You cannot perform memory tests while other tests that allocate and use memory within the region are performing. However, you can
perform the Read tests concurrently with other processes. You cannot run multiple memory tests at the same time as they may collide
within the memory spaces.
Memory tests cannot test all the memory, and without cache ushes, memory tests may not get out of the caches. The SDI must ensure
the memory accessed is accessing the physical memory. This check slows down the tests.
Data ow
The memtool is not part of the data path and does not participate in the data ow.
nputool
The nputool allows for conguring and testing the switch ASICs.
The nputool tests the NPU in the system. The nputool veries that ports are up and trac between the ports is working either using
the CPU-generated packet or using IXIA connected to port-1 and port-2 based on the conguration.
Tests
Tests are shown in the following sections.
CLI options
The nputool shows the available options with the nputool -h or nputool command.
