M4300 Intelligent Edge Series Fully Managed Stackable Switches The DiffServ feature supports the following types of traffic policing treatments (actions): • drop. The packet is dropped • mark cos. The 802.1p user priority bits are (re)marked and forwarded • mark dscp. The packet DSCP is (re)marked and forwarded • mark prec. The packet IP Precedence is (re)marked and forwarded • send: the packet is forwarded without DiffServ modification 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 determining 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. The color of exceeding traffic can be optionally specified as well. • 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. See the Statistics section of this document for more details. • Assigning QoS Queue. Directs 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 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/Policy and attach it to a switch interface, follow these steps: 1. From the QoS Class Configuration page, create a new class with the following settings: • Class Name: Class1 • Class Type: All For more information about this page, see Configure a DiffServ Class on page 485. 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 Configuration Examples 704 User Manual
