(Normal–7) for forwarding packets received with the specified frame Type
information.

Broadcast Suppression
From the Broadcast Statistics and Suppression window, you can monitor
broadcast peak statistics, and suppress the amount of broadcast frames received
on each interface on your MultiSwitch 700 module (thereby protecting your
network from broadcast storms). Specifically, you can monitor the number of
frames each interface is receiving, and set limits on how many of those broadcast
frames will be forwarded to the other interfaces. Once a threshold has been
reached on an interface, broadcast frames will be dropped. From the Broadcast
Statistics and Suppression window, you can set a unique threshold for each
interface on a frames per second basis.
To access the Broadcast Statistics and Suppression window:
1. Click on the module index of the module of interest to display the Module
menu.
2. Select Broadcast Suppression. The Broadcast Statistics and Suppression
window,
Figure 2-24 , opens.
NOTE
Since the MultiSwitch 700 module has two transmit queues, a priority of Normal will
cause packets to be forwarded through the lower priority queue, and any priority of 1
through 7 will cause the packets to be forwarded through the higher
priority queue.
