Hi Olivier,
Reading through "Dropping packets at high rate" on bsdrp.org I found a good
solution for a project. Unfortunately I could not be 100% sure if the ACL
in Chelsio cards is drop-all by default or allow-all by default. I suppose
it is allow-all by default. I don't have a spare card at the moment but
would like to test if I can drop some packages destined to a server at a
given port. Since I have only a production system at the moment I would
like to ask you:
- is it safe to add rules on the fly in BSDRP?
- is it safe to implement drop only rules on a production server without
breaking the other traffic (should I have an allow-all in the end)?
I would like to test dropping all packets incoming on cxl0 from any host to
host 192.168.1.122 with destination port 23. I suppose a rule like the
following will do the job:

#cxgbetool t5nex0 filter 10 iport 0 action drop dip 192.168.1.122 dport 23

If I want this persistent I should create a script probably and start it
with the system boot?
How many rules can I plug in?

Regards,
Lyubomir
