The following table describes the labels in this screen.
16.8 DiffServ
This feature is not available on all models.
DiffServ is a class of service (CoS) model that marks packets so that they receive specific per-
hop treatment at DiffServ-compliant network devices along the route based on the application
types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the
level of service desired. This allows the intermediary DiffServ-compliant network devices to
handle the packets differently depending on the code points without the need to negotiate
paths or remember state information for every flow. In addition, applications do not have to
request a particular service or give advanced notice of where the traffic is going.
Enable DiffServ in the DiffServ screen.
1 In the Device Panel list, select a device and then right-click.
2 Click Configuration, Ethernet Port Configuration and the DiffServ tab.
3 Select Active to enable the DSCP-to-IEEE 802.1q mapping. Set the mapping in the
System Configuration: DSCP screen. See
Section 14.10 on page 126.

Table 69 Ethernet Port Configuration: Broadcast Storm Ctrl.
LABEL DESCRIPTION
Active Select Active to enable broadcast storm control.
Note: For GS-2024, configure rate limiting settings in the Switch
Configuration: Switch Setup screen. Refer to
Section 14.1 on
page 110.
Rate Specify the traffic a port receives in kilobits per second (Kbps).
• If you enter a number between 64 and 1728, the switch automatically rounds the
number down to the nearest multiple of 64.
• If you enter a number between 1729 and 1999, the rate is fixed at 1792.
• If you enter a number between 2000 and 103999, the switch rounds the number
down to the nearest multiple of 1000.
• On a Gigabit Ethernet/ Mini-GBIC port, the switch rounds a number down to the
nearest multiple of 8000 for a number between 104000 and 1000000.
Broadcast Select this option and specify how many broadcast packets the port receives per second.
Multicast Select this option and specify how many multicast packets the port receives per second.
DLF Select this option and specify how many destination lookup failure (DLF) packets the port
receives per second.
