Configuring Basic Threat Detection Statistics
This section describes how to configure basic threat detection statistics, including enabling or disabling
it and changing the default limits.
Detailed Steps

seconds.
800 drops/sec over the last 20
second period.
320 drops/sec over the last
3600 seconds.
640 drops/sec over the last 120
second period.

• Packets failed application

Command Purpose
Step 1
threat-detection basic-threat
Example:
hostname(config)# threat-detection
basic-threat
Enables basic threat detection statistics (if you previously
disabled it). Basic threat detection is enabled by default.
Step 2
threat-detection rate {acl-drop |
bad-packet-drop | conn-limit-drop |
dos-drop | fw-drop | icmp-drop |
inspect-drop | interface-drop |
scanning-threat | syn-attack}
rate-interval rate_interval average-rate
av_rate burst-rate burst_rate
Example:
hostname(config)# threat-detection rate
dos-drop rate-interval 600 average-rate 60
burst-rate 100
(Optional) Changes the default settings for one or more type of
event.
For a description of each event type, see the “Information About
Basic Threat Detection Statistics” section on page 1-2.
When you use this command with the scanning-threat keyword,
it is also used in the scanning threat detection feature (see the
“Configuring Scanning Threat Detection” section). If you do not
configure basic threat detection, you can still use this command
with the scanning-threat keyword to configure the rate limits for
scanning threat detection.
You can configure up to three different rate intervals for each
event type.
