Displaying Server Traffic information
The show server traffic command displays four counters that help to analyze incoming traffic and
determine the DOS attack occurrence. Be sure to issue show Layer 4 traffic from the SSM CPU (not
the MP).
Syntax: show server traffic
TABLE 7 Field Descriptions for show Layer 4 traffic
Field Description
last conn rate Rate of TCP traffic per second. This includes all TCP traffic, including TCP SYN DoS
attacks
max conn rate Peak rate of TCP traffic (per second) encountered on this device.
last TCP attack rate Rate of TCP Dos attacks per second. This rate is delayed by 1 to 2 minutes.
max TCP attack rate Peak rate of TCP DoS attacks (per second) encountered on this device. This rate is
delayed by 1 to 2 minutes.
