| Congestion Control
Automatic Traffic Control
– 244 –
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.
Command Usage
◆ 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).
◆ 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 245).
Parameters
These parameters are displayed:
◆ Broadcast Apply Timer – The interval after the upper threshold has been
exceeded at which to apply the control response to broadcast storms.
(Range: 5-300 seconds; Default: 300 seconds)
◆ Broadcast Release Timer – The time at which to release the control response
after ingress traffic has fallen beneath the lower threshold for broadcast storms.
(Range: 5-900 seconds; Default: 900 seconds)
◆ Multicast Apply Timer – The interval after the upper threshold has been
exceeded at which to apply the control response to multicast storms.
(Range: 5-300 seconds; Default: 300 seconds)
◆ Multicast Release Timer – The time at which to release the control response
after ingress traffic has fallen beneath the lower threshold for multicast storms.
(Range: 5-900 seconds; Default: 900 seconds)
Web Interface
To configure the response timers for automatic storm control:
1. Click Traffic, Auto Traffic Control.
2. Select Configure Global from the Step field.
3. Set the apply and release timers for broadcast and multicast storms.
4. Click Apply.
