  • Page 6: Configuring Acls

    Configuring ACLs An access control list (ACL) is a set of rules (or permit or deny statements) for identifying traffic based on criteria such as source IP address, destination IP address, and port number. Overview ACLs are primarily used for packet filtering. "Configuring packet filtering with ACLs"...

  • Page 7: Match Order

    Match order The rules in an ACL are sorted in a specific order. When a packet matches a rule, the device stops the matching process and performs the action defined in the rule. If an ACL contains overlapping or conflicting rules, the matching result and action to take depend on the rule order. The following ACL match orders are available: •...

  • Page 8: Rule Numbering

    Traditional packet filtering matches only first fragments of packets, and allows all subsequent non-first fragments to pass through. Attackers can fabricate non-first fragments to attack networks. To avoid the risks, the HP ACL implementation does the following: Filters all fragments by default, including non-first fragments.

  • Page 19: Qos Overview

    QoS overview In data communications, Quality of Service (QoS) is a network's ability to provide differentiated service guarantees for diversified traffic in terms of bandwidth, delay, jitter, and drop rate. Network resources are scarce. The contention for resources requires that QoS prioritize important traffic flows over trivial ones.

  • Page 20: Qos Techniques

    QoS techniques The QoS techniques include traffic classification, traffic policing, traffic shaping, rate limit, congestion management, and congestion avoidance. The following section briefly introduces these QoS techniques. Figure 3 Position of the QoS techniques in a network As shown in Figure 3, traffic classification, traffic shaping, traffic policing, congestion management, and congestion avoidance mainly implement the following functions:...

  • Page 21: Qos Configuration Approaches

    QoS configuration approaches This chapter describes the QoS configuration approaches. Overview You can configure QoS in the following approaches: MQC approach • • Non-MQC approach Some features support both approaches, but some support only one. MQC approach In the modular QoS configuration (MQC) approach, you configure QoS service parameters by using QoS policies.

  • Page 22: Defining A Class

Configuration guidelines If a class that uses the AND operator has multiple if-match acl, if-match acl ipv6, if-match customer-vlan-id or if-match service-vlan-id clauses, a packet that matches any of the clauses matches the class.

  • Page 27: Configuring Priority Mapping

    Configuring priority mapping This chapter describes how to configure priority mapping. Overview When a packet arrives, depending on your configuration, a device assigns a set of QoS priority parameters to the packet based on either a certain priority field carried in the packet or the port priority of the incoming port.

  • Page 28: Priority Trust Mode On A Port

    Priority trust mode on a port The priority trust mode on a port determines which priority is used for priority mapping table lookup. Port priority was introduced to use for priority mapping in addition to the priority fields carried in packets. The device provides the following priority trust modes: Using the 802.1p priority carried in packets for priority mapping.

  • Page 29: Priority Mapping Configuration Task List

  • Page 35: Configuring Traffic Policing, Traffic Shaping, And Rate Limit

    Configuring traffic policing, traffic shaping, and rate limit This chapter describes how to configure traffic policing, traffic shaping, and rate limit. Overview Traffic policing, traffic shaping, and rate limit are QoS techniques that help assign network resources, such as assigning bandwidth. They increase network performance and user satisfaction. For example, you can configure a flow to use only the resources committed to it in a certain time range.

  • Page 36: Traffic Policing

CBS—Size of bucket C, which specifies the transient burst of traffic that bucket C can forward. • Excess burst size (EBS)—Size of bucket E, which specifies the transient burst of traffic that bucket E •...

  • Page 37: Traffic Shaping

    Traffic shaping Traffic shaping shapes the outbound traffic. Traffic shaping limits the outbound traffic rate by buffering exceeding traffic. You can use traffic shaping to adapt the traffic output rate on a device to the input traffic rate of its connected device to avoid packet loss.

  • Page 38: Configuring Traffic Policing

    Rate limit also uses token buckets for traffic control. With rate limit configured on an interface, all packets to be sent through the interface are handled by the token bucket for rate limiting. If enough tokens are in the token bucket, packets can be forwarded. Otherwise, packets are put into QoS queues for congestion management.

  • Page 44: Configuring Congestion Management

    Configuring congestion management This chapter describes how to configure congestion management. Overview This section describes why congestion occurs and the congestion management techniques. Causes, impacts, and countermeasures Network congestion degrades service quality. Congestion is a situation where the forwarding rate decreases due to insufficient resources, resulting in extra delay.

  • Page 45

    SP queuing SP queuing is designed for mission-critical applications that require preferential service to reduce the response delay when congestion occurs. Figure 14 SP queuing Figure 14, SP queuing classifies eight queues on a port into eight classes, numbered 7 to 0 in descending priority order.

    Figure 15 WRR queuing Queue 0 Weight 1 Packets to be sent through this port Queue 1 Weight 2 Sent packets Interface …… Queue N-2 Weight N-1 Queue Sending queue Packet scheduling classification Queue N-1 Weight N Assume a port provides eight output queues. WRR assigns each queue a weight value (represented by w7, w6, w5, w4, w3, w2, w1, or w0) to decide the proportion of resources assigned to the queue.

  • Page 47

    Compared with WRR, WFQ can work with the minimum guaranteed bandwidth as follows: • By setting the minimum guaranteed bandwidth, you can make sure that each WFQ queue is assured of certain bandwidth. The assignable bandwidth is allocated based on the priority of each queue (assignable bandwidth •...

    Configuring congestion avoidance This chapter describes how to configure congestion avoidance.
