SETTING THE
ATC TIMERS
Use the Traffic > Auto Traffic Control (Configure Global) page to set the
time at which to apply the control response after ingress traffic has
exceeded the upper threshold, and the time at which to release the control
response after ingress traffic has fallen beneath the lower threshold.
CLI REFERENCES
â—† "auto-traffic-control apply-timer" on page 1000
â—† "auto-traffic-control release-timer" on page 1000
COMMAND USAGE
â—† After the apply timer expires, the settings in the Traffic > Automatic
Traffic Control (Configure Interface) page are used to determine if a
control action will be triggered (as configured under the Action field) or
a trap message sent (as configured under the Trap Storm Fire field).
â—† The release timer only applies to a Rate Control response set in the
Action field of the ATC (Interface Configuration) page. When a port has
been shut down by a control response, it must be manually re-enabled
using the Manual Control Release (see page 265).
