Access Point/Bridge Messages
Error Message Saving this config to nvram may corrupt any network management or
security files stored at the end of nvram. Continue? [no]:
Explanation
This warning message displays on the access point CLI interface while saving
configuration changes through the CLI. This is due to insufficient space in flash memory. When a
radio crashes, .rcore files are created. These files indicate a firmware or a hardware problem in the
radio, although a hardware problem is less likely.
Recommended Action This warning message can be prohibited by removing the rcore files generated
in flash memory. The rcore files have a .rcore extension. The files can be deleted because they
simply show that the radio went down at some point. The .rcore files can be listed on the CLI session
and appear similar to this:
r15_5705_AB50_A8341F30.rcore
