Insight Managed 8-Port Gigabit Ethernet Smart Cloud Switch with 2 SFP Fiber Ports
• Policing with color mode awareness. Policing in the DiffServ feature uses either color
blind or color aware mode. Color blind mode ignores the coloration (marking) of the
incoming packet. Color aware mode takes into consideration the current packet marking
when the switch determines the policing outcome. An auxiliary traffic class is used in
conjunction with the policing definition to specify a value for one of the 802.1p, secondary
802.1p, IP DSCP, or IP precedence fields designating the incoming color value to be
used as the conforming color. You can also specify the color of traffic that exceeds the
threshold.
• Counting. Updating octet and packet statistics to keep track of data handling along traffic
paths within DiffServ. In this DiffServ feature, counters are not explicitly configured by the
user, but are designed into the system based on the DiffServ policy being created. For
more information, see View DiffServ Service Statistics on page 236.
• Assigning QoS queue. Directs a traffic stream to the specified QoS queue. This allows a
traffic classifier to specify which one of the supported hardware queues are used for
handling packets belonging to the class.
• Redirecting. Forces a classified traffic stream to a specified egress port (physical or
LAG). This can occur in addition to any marking or policing action. It can also be specified
along with a QoS queue assignment.
DiffServ Example Configuration
To create a DiffServ class and policy and attach them to a switch interface, follow these
steps:
1. On the Class Configuration page (see Create and Configure a DiffServ Class on
page 218), create a new class with the following settings:
• Class Name. Class1
• Class Type. All
2. Click the Class1 hyperlink to view the DiffServ Class Configuration page for this class.
3. Configure the following settings for Class1:
• Protocol Type. UDP
• Source IP Address. 192.12.1.0.
• Source Mask. 255.255.255.0.
• Source L4 Port. Other, and enter 4567 as the source port value.
• Destination IP Address. 192.12.2.0.
• Destination Mask. 255.255.255.0.
• Destination L4 Port. Other, and enter 4568 as the destination port value.
