Usage guidelines Within an ACL, the permit or deny statement of each rule must be unique. If the ACL rule you are creating or editing has the same deny or permit statement as another rule in the ACL, your creation or editing attempt fails. To view rules in an ACL and their rule IDs, use the display acl ipv6 all command. Examples # Create an IPv6 advanced ACL rule to permit TCP packets with the destination port 80 from 2030:5060::/64 to FE80:5060::/96, and enable logging matching packets.
Use undo rule to delete an entire IPv6 basic ACL rule or some attributes in the rule. If no optional keywords are provided, this command deletes the entire rule. If optional keywords or arguments are provided, this command deletes the specified attributes.
Usage guidelines Within an ACL, the permit or deny statement of each rule must be unique. If the ACL rule you are creating or editing has the same deny or permit statement as another rule in the ACL, your creation or editing attempt fails. To view rules in an ACL and their rule IDs, use the display acl ipv6 all command. Examples # Create an IPv6 basic ACL rule to deny the packets from any source IP segment but 1001::/16, 3124:1123::/32, or FE80:5060:1001::/48.
[Sysname-acl-basic-2000] rule 0 deny source 1.1.1.1 0 [Sysname-acl-basic-2000] rule 0 comment This rule is used on GigabitEthernet 0/0./1. # Create a rule in IPv6 basic ACL 2000 and add a comment about the rule. system-view [Sysname] acl ipv6 number 2000 [Sysname-acl6-basic-2000] rule 0 permit source 1001::1 128 [Sysname-acl6-basic-2000] rule 0 comment This rule is used on GigabitEthernet 0/0.1.
Use the undo rule rule-id remark command to delete a specific rule range remark. If you also specify the text argument, you must type in the remark the same as was specified to successfully remove the remark. • When adding an end remark for a rule range, you can specify the end rule number plus 1 for the rule-id argument so all rules in this range appears between the two remarks. You can also specify the end rule number for the rule-id argument. In this approach, the end rule appears below the end remark.
step Use step to set a rule numbering step for an ACL. The rule numbering step sets the increment by which the system numbers rules automatically. For example, the default ACL rule numbering step is 5. If you do not assign IDs to rules you are creating, they are numbered 0, 5, 10, 15, and so on. The wider the numbering step, the more rules you can insert between two rules. Whenever the step changes, the rules are renumbered, starting from 0.
Syntax time-range time-range-name { start-time to end-time days [ from time1 date1 ] [ to time2 date2 ] | from time1 date1 [ to time2 date2 ] | to time2 date2 } undo time-range time-range-name [ start-time to end-time days [ from time1 date1 ] [ to time2 date2 ] | from time1 date1 [ to time2 date2 ] | to time2 date2 ] Default No time range exists. Views System view Default command level 2: System level Parameters time-range-name: Specifies a time range name.
• Absolute statement in the from time1 date1 to time2 date2 format. An absolute statement does not recur. • Compound statement in the start-time to end-time days from time1 date1 to time2 date2 format. A compound statement recurs on a day or days of the week only within the specified period.
QoS policy commands Class commands display traffic classifier Use display traffic classifier to display class information. Syntax display traffic classifier { system-defined | user-defined } [ classifier-name ] [ | { begin | exclude | include } regular-expression ] Views Any view Default command level 1: Monitor level Parameters system-defined: Displays system-defined classes. user-defined: Displays user-defined classes. classifier-name: Class name, a string of 1 to 31 characters.
Table 14 Command output Field Description Classifier Class name and its match criteria. Operator Match operator you set for the class. If the operator is AND, the class matches the packets that match all its match criteria. If the operator is OR, the class matches the packets that match any of its match criteria. Rule(s) Match criteria. if-match Use if-match to define a match criterion. Use undo if-match to delete a match criterion.
Keyword and argument combination Description any Matches all packets. Matches a QoS class. classifier classifier-name The classifier-name argument is the name of the class. This option is not supported on SAP modules operating in bridge mode. Matches DSCP values. dscp dscp-list The dscp-list argument is a list of up to eight DSCP values. A DSCP value is in the range of 0 to 63. destination-mac mac-address Matches a destination MAC address. Matches the 802.1p priority of the customer network.
If a class that uses the AND operator has multiple if-match customer-vlan-id or if-match service-vlan-id clauses, a packet that matches any of the clauses matches the class. The match criteria listed below must be unique in a class that uses the AND operator. To ensure that the class can be successfully applied to interfaces, avoid defining multiple if-match clauses for these match criteria or inputting multiple values for any of the list arguments, such as the 8021p-list argument.
{ • Defining a criterion to match 802.1p priority in customer or service provider VLAN tags { { { • { { You can configure up to eight 802.1p priority values in one command line. If the same 802.1p priority value is specified multiple times, the system considers them as one. If a packet matches one of the defined 802.1p priority values, it matches the if-match clause. To delete a criterion that matches 802.1p priority values, the specified 802.
{ { You can configure multiple VLAN IDs in one command line. If the same VLAN ID is specified multiple times, the system considers them as one. If a packet matches one of the defined VLAN IDs, it matches the if-match clause. To delete a criterion that matches VLAN IDs, the specified VLAN IDs in the command must be identical with those defined in the criterion (the sequence can be different).

Default command level 2: System level Parameters behavior-name: Sets a behavior name, a string of 1 to 31 characters. The specified behavior-name must not be a system-defined traffic behavior name like ef, af, be, or be-flow-based. Usage guidelines A traffic behavior is a set of actions, such as priority marking, dropping, rate limiting, and accounting. You provide QoS for a class of traffic by associating a traffic behavior with the class of traffic. Examples # Create a traffic behavior named behavior1.
• A parent policy can nest only one child policy. This child policy cannot be the parent policy itself or the parent of any other policy. • You can reference only one child policy in a behavior. • If` the parent policy and the child policy contain the same behavior, the system performs the behavior in the parent policy first and then that in the child policy.
Usage guidelines You cannot remove a default class. You can perform a set of QoS actions on a traffic class by associating a traffic behavior with the traffic class. You can configure multiple class-behavior associations in a QoS policy, and each class can associate with only one traffic behavior. If the specified class or traffic behavior does not exist, the system creates a null class or traffic behavior. Examples # Associate traffic class database with traffic behavior test in QoS policy user1.
Examples # Display the configuration information of user-defined QoS policies.

system-view [Sysname] fr class test1 [Sysname-fr-class-test1] ebs 32000 Related commands • cbs • cir allow • cir fifo queue-length Use fifo queue-length to set the FIFO queue length for FR PVCs. Use undo fifo queue-length to restore the default. Syntax fifo queue-length queue-length undo fifo queue-length Views FR class view Default command level 2: System level Parameters queue-length: FIFO queue length, which specifies the maximum number of packets that a FIFO queue can hold.
Default No FR class is created. Views System view Default command level 2: System level Parameters class-name: Name of an FR class, a string of 1 to 30 characters. Usage guidelines The FR class parameters do not take effect until you associate the FR class with an interface or PVC and enable the FR QoS function on the interface. With an FR class removed, all the associations associating this FR class with an interface or a DLCI are released. Examples # Create an FR class test1.
queue-percentage: Congestion threshold, expressed in the interface queue utilization rate, which means the percentage of the current interface queue length to the total queue length. The value range for this argument is 1 to 100, and the default is 100. Usage guidelines This command is similar to the congestion-threshold command. The difference between the two commands lies in that: this command is applicable to FR interfaces and the congestion-threshold command is applicable to FR PVCs.
Examples # Apply DE rule list 3 to DLCI 100 of Serial 2/0/1. system-view [Sysname]interface Serial 2/0/1 [Sysname-Serial2/0/1] fr dlci 100 [Sysname-Serial2/0/1] fr de del 3 dlci 100 Related commands • fr del inbound-interface • fr del protocol fr del inbound-interface Use fr del inbound-interface to configure an interface-based DE rule list. Before the incoming packets of the specific interfaces are to be forwarded as FR packets, the DE flag bits of these packets are set to 1.
fr del protocol Use fr del protocol ip to configure an IP protocol-based DE rule list. The DE flag bits of FR packets encapsulated with the IP packets matching the specific rule are set to 1. Use undo fr del protocol ip to remove the specific DE rules from the DE rule list.
Examples # Add a rule that sets the DE flag bits of all the FR packets encapsulated with IP packets to 1 to DE rule list 1. system-view [Sysname] fr del 1 protocol ip Related commands • fr de del • fr del inbound-interface fr traffic-policing Use fr traffic-policing to enable FR traffic policing. Use undo fr traffic-policing to disable FR traffic policing.
Default FRTS is disabled. Views FR interface view, MFR interface view Default command level 2: System level Usage guidelines FRTS is applied to the outgoing interfaces and are usually applied to the DCE of an FR network. Examples # Enable FRTS on Serial 2/0/1.
[Sysname] fr class test1 [Sysname-fr-class-test1] fragment 128 Related commands fr class fr-class Use fr-class to associate an FR class with the current FR PVC or FR interface. Use undo fr-class to cancel the association. Syntax fr-class class-name undo fr-class class-name Default No FR class is associated with an FR PVC or an FR interface. Views FR DLCI view, FR interface view Default command level 2: System level Parameters class-name: Name of an FR class, a string of 1 to 30 characters.
pq Use pq to apply PQ to the FR PVCs. Use undo pq to restore the default queuing (FIFO queuing). Syntax pq pql pql-index undo pq Default FR PVCs adopt FIFO queuing. Views FR class view Default command level 2: System level Parameters pql-index: PQL index in the range of 1 to 16. Examples # Apply PQL 10 to the FR class test1.
Parameters bottom: Specifies the bottom queue. middle: Specifies the middle queue. normal: Specifies the normal queue. top: Specifies the top queue. Usage guidelines PVC PQ queues include the top queue, the middle queue, the normal queue, and the bottom queue, in descending priority order. The packets of a given PVC can only be assigned to a specific queue. Examples # Assign packets from the PVCs associated with the FR class test1 to the top queue of PVC PQ.
preferentially within the configured bandwidth. When no congestion occurs to the PVC, packets destination to the UDP ports within the specified range can be transmitted using the available bandwidth of the PVC. The UDP port range for VoIP is generally configured as 16384 to 37267. Examples # Apply RTPQ to the FR class test1 and set the RTP priority queue length to 20 kbps.
