Symptom
ISE DACL Syntax validator considers ACL containing entry with an empty remark text as valid. As per Cisco ASA's usage guidelines:
"The remark text must contain at least one non-space character; an empty remark is not allowed. The remark text can be up to 100 characters long, including spaces and punctuation."
Conditions
DACL configured on ISE contains a line with an empty remark text
Workaround
Verify DACL syntax using documentation associated with Network Access Device.
