data received on the RF path
contains errors at a higher
rate than the defined error
rate threshold.

Payload
Decryption
Failure
warning(4)
Sample Duration
Type
Alarm to indicate that
packets have been received
over the air where the radio
has failed to decrypt the
content.
Check the event history log
for more details. If the
decryption failure is solely
due to security setting
mismatch, then the security
settings of the radios
involved needs to be checked
and corrected. If the
decryption failure is also
possibly due to a security key
mismatch, then this indicates
that another unauthorized
radio is attempting to
connect to the radio
network, or an authorized
radio has got an invalid key
that needs updating.
