In order to calculate the time since peak, subtract the value in the Time Since Peak column

TIP from the current sysUpTime displayed as Up Time in the front panel. Please note that the

peak time you calculate will be within 5 minutes of the actual time since peak, as sysUpTime is polled by default at 3 minute intervals and the broadcast suppression values are polled by default at 2 minute intervals.

To reset the Peak Rate and Time Since Peak values:

1.Shift-click to select one or more interfaces for which you want to reset the values.

2.Click on the Reset Peak Rate and Peak Time on Selected Ports: drop-down list box, and drag to select YES.

3.Click on the Apply button. The Peak Rate and Time Since Peak values will be reset for the selected interfaces.

Threshold

The maximum number of received broadcast frames that may be forwarded by this interface to other interfaces on the device. Any number of broadcast frames received over this threshold will be dropped. The default value for the interface is near the theoretical maximum frames per second for the interface, i.e., 14,880 for 10Mb Ethernet interface, 148,880 for 100Mb Ethernet or 1,488,800 for Gigabit Ethernet.

To change the Receive Broadcast Threshold:

1.Shift-click to select one or more interfaces for which you want to change the broadcast packet threshold.

2.Highlight the value currently in the Receive Broadcast Threshold on Selected Ports: field and type in a new broadcast threshold value. Allowable values begin at 10 and proceed in multiples of ten.

NOTE

When you enter a value less than 10, the threshold will default to a value of 0. If you enter a value that is not a multiple of 10 it will round down to the last multiple of 10, i.e., if you enter 15 as the new threshold value, the threshold value will be set to 10; if you enter 49 as the new threshold value, the threshold value will be set to 40.

3.Click on the Apply button. The new threshold will be applied to the selected interfaces. Any broadcast frames received by the interface exceeding the set threshold will be dropped.
