11 Chapter 1 QoS Commands Chapter 1 QoS Commands 1.1 QoS Commands Caution: Service processor cards do not support Layer 2 ACL. The four ports (numbered 0 to 3) on an XP4B or XP4CA card each support four queues (queue 0 to 3) and support the configuration for queue scheduling. The following configurations can only be performed on port 0 and 2: applying user-defined flow template, configuring port local precedence, packet filtering, priority marking, traffic policing, traffic redirecting, traffic mirroring, and traffic accounting. When such a configuration is performed on port 0, it takes effect on both port 0 and 1. Likewise, when such a configuration is performed on port 2, it takes effect on both port 2 and 3. With traffic policing configured on a XP4B or XP4CA card, port 0 and 1 share the same bandwidth, and port 2 and 3 do likewise. That is, port 0 and 1 share the traffic parameter settings on port 0, and port 2 and 3 share the traffic parameter settings on port 2. On an XP4B or XP4CA card, executing the traffic-statistic command on port 0 will collect traffic statistics on both port 0 and 1, and executing the command on port 2 will collect traffic statistics on both port 2 and 3. Ports on XP4B and XP4CA cards do not support traffic shaping (the traffic-shape command) display mirroring-group display mirroring-group [ groupid ] Any view groupid: Mirroring group ID, in the range of 1 to

12 Chapter 1 QoS Commands Use the display mirroring-group command to view the configuration of a port mirroring group. The information displayed includes the mirroring ports, direction of monitored packets, and monitor ports.

If a conform level is specified, only the specified mapping table for the conform level is displayed. If no conform level is specified, the mapping tables of the specified type for all the conform levels are displayed. dscp-policed-service-map [ dscp-list ]: Displays the DSCP-to-services mapping table for the specified conform level or displays all DSCP-to-services mapping tables if no conform level is specified. The dscp-list argument can be a single DSCP or a range of DSCPs separated by spaces, for example, If the dscp-list argument is specified, only the mapping entries for the specified DSCP(s) will be displayed; if not, the entire DSCP-to-service mapping table or tables are displayed. exp-policed-service-map: Displays the EXP-to-services mapping table for the specified conform level or displays all EXP-to-services mapping tables if no conform level is specified. EXP is the priority field of MPLS packets. local-precedence-cos-map: Displays the local precedence-to-802.1p mapping table for the specified conform level or displays all local precedence-to-802.1p mapping tables if no conform level is specified. Use the display qos conform-level command to display QoS priority mapping tables. 1-2

25 Chapter 1 QoS Commands r (prefix) exponent Parameter Represents red packets Exponent value used in the formula of WRED to calculate mean queue length drop-mode drop-mode { tail-drop wred } [ wred-index ] undo drop-mode Ethernet port view tail-drop: Tail drop mode. wred: WRED drop mode. wred-index: WRED index, in the range of 0 to 3. By default, it is 0. If you type nothing for this parameter, the system will use the parameters specified when WRED index is 0. Use the drop-mode command to configure drop mode for a port. Use the undo drop-mode command to restore the default drop mode, i.e. tail drop mode. By default, tail drop mode is adopted. When congestion occurs, the switch drops packets to release queues resources and no longer puts packets into long-delay queues. The following two drop modes are available: Tail drop mode: different queues (red, yellow and green) are allocated with different drop thresholds. When these thresholds are exceeded respectively, excessive packets will be dropped. WRED drop mode: Drop precedence is taken into account in drop action. When only the lower threshold of a color (red, yellow, or green) is exceeded, packets in this color between the lower threshold and higher threshold are dropped randomly at a given slope. But when the higher threshold of a color (red, yellow, or green) is exceeded, all exceeding packets in this color are dropped. 1-15

31 Chapter 1 QoS Commands system-index index: System index for the specified ACL rule. Normally, when applying a rule, the system assigns a globally unique index to it for later retrieval. Alternatively, you can choose to assign a system index to an ACL rule with this command. However, as this value may change while the system is running, you are not encouraged to manually assign system indexes to ACL rules. Note: If the specified index is 0, the system selects an index automatically. cpu: Mirrors traffic to the CPU. interface interface-type interface-number: Mirrors traffic to the interface specified by its type and number. slot slot-id: Mirrors traffic to the NetStream card seated in the slot specified by slot-id. Use the mirrored-to command to reference an ACL (or an ACL rule) and mirror data streams to the CPU, the specified port, or the specified NetStream card. Use the undo mirrored-to command to remove traffic mirroring setting. This configuration is only applicable to the packets which match the permit statements in the ACL. For traffic mirroring configuration restrictions, refer to QoS Configuration. Related commands: display qos-interface mirrored-to. # Mirror the packets which match the permit statements in the ACL 2000 to CPU. <H3C> system-view System : return to User with Ctrl+Z.

Use the mirroring-group command to configure a port mirroring group. Use the undo mirroring-group command to remove the specified port mirroring group. The switch supports multiple-to-one mirroring, that is, copying the packets from several mirroring ports to the monitor port. The mirroring function on the S9500 series is implemented through mirroring groups. Each mirroring group contains one monitor port and at least one mirroring ports. In addition, you can specify the direction of monitored packets. For port mirroring configuration restrictions, refer to QoS Configuration. 1-22

The switch provides four sets of default WRED parameters, respectively numbered as 0, 1, 2 and 3. Each set includes 80 parameters, 10 parameters for each of the eight queues. The ten parameters are green-min-threshold, yellow-min-threshold, red-min-threshold, green-max-threshold, yellow-max-threshold, red-max-threshold, green-max-prob, yellow-max-prob, red-max-prob and exponent. You can use the command to modify the parameters of a specific WRED index. # Configure parameters for WRED 0: queue-id is 7; green-min-threshold is 150; green-max-threshold is 500; green-max-prob is 5; yellow-min-threshold is 100; yellow-max-threshold is 150; yellow-max-prob is 10; red-min-threshold is 50; red-max-threshold is 100; red-max-prob is 15; exponent is 10. <H3C> system-view System : return to User with Ctrl+Z.

40 Chapter 1 QoS Commands Use the queue-scheduler command to choose queue scheduling algorithm and parameters. Use the undo queue-scheduler command to restore the default setting, SP algorithm. By default, the SP algorithm is adopted for all output queues at a port. The switch supports eight output queues at a port, with different scheduling algorithms for them. You can assign these queues to different scheduling groups: SP group, WRR priority group 1 and group 2. For example, you can assign queues 6 and 7 to the SP group, queues 0, 1 and 2 to WRR priority group 1 and queues 3, 4 and 5 to WRR priority group 2. Then a queue will be selected from each group according to its own scheduling algorithm. The three selected queues will scheduled by the SP algorithm. The queue weight is based on bandwidth. For example, if queues 0, 1 and 2 belong to WRR priority group 1 and their weight is respectively configured as 20, 20 and 30, then during process, the proportion of their respective weight in the whole bandwidth is 20:20:30 # Configure queues 0 to 5 to adopt the WRR algorithm. Assign queues 0, 1 and 2 to group 1, with weight 20, 20 and 30; and assign queues 3, 4 and 5 to group 2, with weight 20, 20 and 40.

Use the reset traffic-statistic command to clear statistics of all traffic or traffic matching a specific ACL. Table 1-8 Comparison between two statistics clearing commands Command reset acl counter reset traffic-statistic Clears ACL statistics. This command is for the ACLs that perform filtering and traffic classification to the packets processed by software. The cases for software to import ACLs include ACL importing for routing policy, ACL importing for registered user control. The ACL ID available here is in the range of 2000 to Clear traffic statistics. This command is for the ACLs sent to hardware for packet filtering and traffic classification.
