[. . . ] Starting with the highest priority class of service (Class 3), the highest priority class of service will transmit all of the packets and empty its buffer before allowing the next lower priority class of service to transmit its packets. The next highest priority class of service will empty before proceeding to the next class of service and so on. Lower priority classes of service are allowed to transmit only if the higher priority classes of service in the buffer are completely emptied. Packets in the higher priority classes of service are always emptied before any in the lower priority classes of service regardless of latency or volume of the lower priority classes of service. The default settings for QoS scheduling employ this strict priority scheme to empty priority classes of service. The config scheduling command can be used to specify the round robin rotation by which these four hardware priority classes of service are reduced. The weight parameter allows specification of the maximum number of packets a given priority classes of service can transmit before allowing the next lowest priority queue to begin transmitting its packets. A value between 0 and 55 packets can be specified. For example, if a value of 5 is specified, then the highest priority class of service (queue 3) will be allowed to transmit 5 packets. Then the next lower priority class of service (queue 2) will be allowed to transmit 5 packets, and so on, until all of the classes of service have transmitted 5 packets. Parameters <class_id> - Specifies which of the four priority classes of service to which the config scheduling command will be applied. The four 83 DES-30XX Layer 2 Switch CLI Reference Manual config scheduling priority classes of service are identified by number - from 0 to 3 - with class 3 being the highest priority. weight <value 1-55> - Specifies the maximum number of packets the above specified priority class of service will be allowed to transmit before allowing the next lowest priority classes of service to transmit its packets. A value between 1 and 55 packets can be specified. The default value is per class is: Class 0 1 2 3 Restrictions Example usage: To configure traffic scheduling: DES-3026:4# config scheduling 3 weight 15 Command: config scheduling 3 weight 15 Success. DES-3026:4# Weight 1 2 4 8 Only administrator-level users can issue this command. show scheduling Purpose Syntax Description Used to display the currently configured traffic scheduling on the Switch. show scheduling The show scheduling command displays the current configuration for the maximum number of packets (weight) value assigned to the four priority classes of service on the Switch. The Switch will empty the four hardware classes of service in order, from the highest priority (class 3) to the lowest priority (class 0). None. Parameters Restrictions Example usage: To display the current scheduling configuration: 84 DES-30XX Layer 2 Switch CLI Reference Manual DES-3026:4# show scheduling Command: show scheduling QOS Output Scheduling Class ID Weight --------------- ------------Class-0 1 Class-1 2 Class-2 4 Class-3 15 DES-3026:4# config 802. 1p user_priority Purpose Syntax Description Used to map the 802. 1p user priority of an incoming packet to one of the four hardware classes of service available on the Switch. config 802. 1p user_priority <priority 0-7> <class_id 0-3> The config 802. 1p user_priority command is used to configure the way the Switch will map an incoming packet, based on its 802. 1p user priority tag, to one of the four hardware priority classes of service available on the Switch. The Switch's default is to map the incoming 802. 1p priority values to the four hardware classes of service according to the following chart: 802. 1p Switch Priority Value Queue -------------------------0 1 1 0 2 0 3 1 4 2 5 2 6 3 7 3 <priority 0-7> - Specifies to which of the eight 802. 1p priority values (0 through 7) to map to one of the Switch's hardware priority classes of service (<class_id>, 0 through 3). <class_id 0-3> - Specifies to which of the Switch's hardware priority classes of service the 802. 1p priority value (specified above) will be mapped.
