I've been running the ASA Botnet Filter in my demo lab pretty much since the feature came out. I demo the feature quite a bit because it is always picking up bad traffic and it shows well. My licesence is current, in fact is has 273 days left:
Botnet Traffic Filter : Enabled 273 days
Just recently I noticed that the stastics are all 0's and no data in the reports is showing. The updater-client is functioning. I can log a blacklist hit, but the ASA does not drop the traffic or show the hit in the statistics. Is this a bug?
Enabled on interface outside
Total conns classified 0, ingress 0, egress 0
Total whitelist classified 0, ingress 0, egress 0
Total greylist classified 0, dropped 0, ingress 0, egress 0
Total blacklist classified 0, dropped 0, ingress 0, egress 0
I don't know when exacly this happened. The latest version I was running was 8.4(3). I tried rolling back to 8.4(2) but still the same. My config hasn't changed. Any ideas?
