It looks like you can use threshold in the threshold.conf file or you can
also use rate_filter to change the action from alert to pass and that might
work as well.

threshold gen_id 1, sig_id 2002087, type both, track by_src, count 3,
seconds 5threshold gen_id 1, sig_id 2002087, type threshold, track
by_src, count 10, seconds 60threshold gen_id 1, sig_id 2002087, type
limit, track by_src, count 1, seconds 15
