Chapter 5: Local Management

5.17BROADCAST SUPPRESSION SCREEN

NOTE

The Broadcast Suppression screen will display only if the operational mode of the device has been set to 802.1D SWITCHING or 802.1Q SWITCHING. Refer to Section 5.7.9, Setting the Operational Mode for instructions on conﬁguring the device to operate in this mode.

The Broadcast Suppression screen, Figure 5-22, allows the user to set a desired limit of receive broadcast frames that are switched out to the other interfaces. This feature limits the amount of broadcast packets to the threshold setting (1 second) and drops all other broadcast packets until the 1 second threshold elapses. This screen also provides statistics about the broadcast activity on ports 1 through 4.

To access the Broadcast Suppression screen from the Device Speciﬁc Conﬁguration Menu screen, use the arrow keys to highlight the BROADCAST SUPPRESSION menu item and press ENTER. The Broadcast Suppression screen displays.
