Configuring the GbE Interconnect Switch using the Web-based Interface
Configuring the Thresholds of Broadcast, Multicast, and DA-Storm Prevention
or Monitoring
The GbE Interconnect Switch allows you to set the threshold (in packets per second) for three
types of storms: broadcast, multicast, and one where the packet destination address (DA) is
unknown. The higher the threshold, the more packets the GbE Interconnect Switch can accept
per second. If the threshold is exceeded, any additional packets received are dropped.
Entering a low value means packets have a greater chance to exceed the threshold and be
dropped from the GbE Interconnect Switch.
To configure the thresholds of broadcast, multicast, and unknown storm prevention or
monitoring:
1. Select Threshold of Broadcast from the Configuration menu. The following screen is
displayed.
2. Select Enabled for the appropriate option.
3. Type a threshold value in the Threshold(Pkts/sec) field.
4. Click Apply to save the changes.
IMPORTANT: To save the configuration settings permanently, you must enter them into NVRAM
using the Save Changes option on the Maintenance menu. Refer to the section, “Saving
Changes,” earlier in this chapter.
Configuring Class of Service, Default Port Priority, and Traffic
Class
This section describes how to configure class of service, default port priority, and traffic
class. For information on how to set the class of service queue options, refer to the
“Configuring Advanced GbE Interconnect Switch Features” section earlier in this chapter.
Class of Service (CoS) for packet prioritization allows you to set priority levels on the GbE
Interconnect Switch for forwarding packets based on the priority setting information in the
packets. The GbE Interconnect Switch supports four classes (0-3) of traffic (buffers or
queues) for implementing priority and allows eight priority levels (0-7) to be mapped to the
four classes. Traffic from a specific server port can be given priority over packets from other
devices according to the range of priority levels.
