diagEnablePost
Enable POST execution at next reboot.
Synopsis
diagEnablePost
Availability admin
Description Use this command to enable Power On Self Test (POST) execution at the
next switch reboot. This mode is saved in flash memory, and POST remains
enabled until it is disabled using the
diagDisablePost
command.
POST includes the following tests:
• ramTest - Bit write / read test of SDRAMS in the switch.
• portRegTest - Bit write / read test of the ASIC SRAMs and registers.
• centralMemoryTest - Bit write / read test of the ASIC central memory.
• cmiTest - ASIC to ASIC connection test of the CMI bus.
• camTest - Functional test of the CAM memory.
• portLoopbackTest - Functional test of switch by sending and receiving
frames from the same port.
For more information about these tests, refer to the individual command
descriptions.
Note
The cold boot (power reset) runs the long ramTest, while the warm
boot (software reset) runs the short ramTest.
Operands None.
Example To enable the POST during future power ons:
switch:admin> diagEnablePost
Committing configuration...done.
On next reboot, POST will be executed.
