Default level

2: System level

Parameters

number acl-number: Specifies the number of an access control list (ACL):

·           2000 to 2999 for IPv4 basic ACLs

·           3000 to 3999 for IPv4 advanced ACLs

·           4000 to 4999 for Ethernet frame header ACLs

·           5000 to 5999 for user-defined ACLs

name acl-name: Assigns a name to the ACL for easy identification. The acl-name argument takes a case-insensitive string of 1 to 63 characters. It must start with an English letter, and to avoid confusion, cannot be all.

match-order: Sets the order in which ACL rules are compared against packets:

·           auto—Compares ACL rules in depth-first order. The depth-first order differs with ACL categories. For more information, see ACL and QoS Configuration Guide.

·           config—Compares ACL rules in ascending order of rule ID. The rule with a smaller ID has higher priority. If no match order is specified, the config order applies by default.

The match-order keyword is not available for user-defined ACLs. They always use the config order.

all: Deletes all IPv4 ACLs, including IPv4 basic, IPv4 advanced, Ethernet frame header, and user-defined ACLs.

Description

Use the acl command to create an IPv4 basic, IPv4 advanced, Ethernet frame header, or user-defined ACL and enter its view. If the ACL has been created, you enter its view directly.

Use the undo acl command to delete the specified IPv4 ACL or all IPv4 ACLs (including IPv4 basic, IPv4 advanced, Ethernet frame header, and user-defined ACLs).

By default, no ACL exists.

You can assign a name to an IPv4 ACL only when you create it. After an ACL is created with a name, you cannot rename it or remove its name.

You can change match order only for ACLs that do not contain any rules.

To display any ACLs you have created, use the display acl command.

Examples

# Create IPv4 basic ACL 2000, and enter its view.

<Sysname> system-view

acl ipv6 enable

Syntax

acl ipv6 enable

acl ipv6 disable

View

System view

Default level

3: Manage level

Parameters

None

Description

Use the acl ipv6 enable command to enable 80-byte ACL rule match mode on an EC or EF card, for example, LSR1GP48LEC1 or LSR1GP48LEF1. This command sets the length limit for the match criteria in each ACL rule to 80 bytes. You must restart the switch to validate the command.

Use the acl ipv6 disable command to restore the default on an EC or EF card.

By default, the 40-byte ACL rule match mode applies to an EC or EF card. The length limit for the match criteria in each ACL rule is 40 bytes.

The acl ipv6 enable command is valid only for an EC or EF card. To support user-defined, IPv6 basic, and IPv6 advanced ACLs on an EC or EF card, you must configure the acl ipv6 enable command first. The other cards support user-defined and IPv6 ACLs by default.

To create an IRF fabric from two switches, make sure that they are using the same ACL rule match mode. For more information about IRF, see IRF Configuration Guide.

For more information about EC and EF cards, see Fundamentals Configuration Guide.

Examples

# Enable 80-byte ACL rule match mode.

Default level

2: System level

Parameters

None

Description

Use the hardware-count enable command to enable counting ACL rule matches performed in hardware. The device automatically counts the rule match counting performed in software.

Use the undo hardware-count enable command to disable counting ACL rule matches performed in hardware. This command also resets the hardware match counters for all rules in the ACL. For a rule configured with the counting keyword, this command only resets the rule’s hardware match counter.

By default, ACL rule matches performed in hardware are not counted.

The hardware-count enable command enables match counting for all rules in an ACL, and the counting keyword in the rule command enables match counting specific to rules. For an individual rule, rule match counting works as long as either the hardware-count enable command or the counting keyword is configured.

The switch does not count ACL rule matches for the outbound ACL deny rules.

Related commands: display acl, display acl ipv6, and rule.

Parameters

acl-number: Specifies an IPv4 ACL by its number:

·           2000 to 2999 for IPv4 basic ACLs

·           3000 to 3999 for IPv4 advanced ACLs

·           4000 to 4999 for Ethernet frame header ACLs

·           5000 to 5999 for user-defined ACLs

name acl-name: Specifies an IPv4 ACL by its name. The acl-name argument takes a case-insensitive string of 1 to 63 characters. It must start with an English letter.

inbound: Filters incoming packets.

outbound: Filters outgoing packets.

Description

Use the packet-filter command to apply an IPv4 basic, IPv4 advanced, Ethernet frame header, or user-defined ACL to an interface to filter packets.

Use the undo packet-filter command to restore the default.

By default, an interface does not filter Layer 2 or IPv4 packets.

The rule you add to an ACL that has been used by a packet filter cannot take effect if hardware resources are insufficient or the packet filter does not support the rule. Such rules are marked as uncompleted in the output of the display acl { acl-number | all | name acl-name } slot slot-number command. To successfully apply the rule, you must delete the rule and reconfigure it when hardware resources are sufficient.

Follow these guidelines when you configure a packet filter on a VLAN interface:

·           Use the undo packet-filter command to remove the packet filter from the VLAN interface if the ACL application fails on an interface card, for example, because of hardware resource insufficiency. The switch applies the packet filter configured on a VLAN interface to the main processing unit and all interface cards. When an application failure occurs on an interface card, the switch cannot automatically remove the ACL that has been applied to the main processing unit or any other interface card.

·           You must also use the undo packet-filter to remove the packet filter if the switch fails to update the packet filter on an interface card after you edit the ACL rules. If you do not remove the packet filter, the old ACL rules continue to take effect and the display packet-filter command shows the initial ACL application status.

Related commands: display packet-filter.

name acl6-name: Specifies an IPv6 ACL by its name. The acl6-name argument takes a case-insensitive string of 1 to 63 characters. It must start with an English letter.

inbound: Filters incoming IPv6 packets.

outbound: Filters outgoing IPv6 packets.

Description

Use the packet-filter ipv6 command to apply an IPv6 basic or IPv6 advanced ACL to an interface to filter IPv6 packets.

Use the undo packet-filter ipv6 command to restore the default.

By default, an interface does not filter IPv6 packets.

The rule you add to an ACL that has been used by a packet filter cannot take effect if hardware resources are insufficient or the packet filter does not support the rule. Such rules are marked as uncompleted in the output of the display acl ipv6 { acl-number | all | name acl-name } slot slot-number command. To successfully apply the rule, you must delete the rule and reconfigure it when hardware resources are sufficient.

2: System level

Parameters

None

Description

Use the packet-filter forwarding-layer route outbound command to set the outbound packet filters on VLAN interfaces to filter only Layer 3 (routed) unicast packets. After you execute this command, the packet-filter outbound command on a VLAN interface filters only Layer 3 unicast packets.

Use the undo packet-filter forwarding-layer route outbound command to restore the default.

By default, an outbound packet filter on a VLAN interface filters all packets, including Layer 2 packets.

When you use the packet-filter forwarding-layer route outbound command or its undo form to specify the outbound packet filter on a VLAN interface to filter only Layer 3 unicast packets or all packets, follow these guidelines:

·           The packet-filter forwarding-layer route outbound command is available only for Ethernet interface cards.

·           The packet-filter forwarding-layer route outbound or its undo form must be configured before the packet-filter { acl-number | name acl-name } outbound command. If you have configured the packet-filter { acl-number | name acl-name } outbound command on a VLAN interface, you must remove the packet filter setting, configure the packet-filter forwarding-layer route outbound or its undo form, and then re-configure the packet-filter { acl-number | name acl-name } outbound command on the VLAN interface.

·           The packet-filter forwarding-layer route outbound command can cause the switch to discard BFD packets. To avoid this problem, configure an advanced ACL rule by using the rule [ rule-id ] permit udp destination-port range 3784 3785 command to permit BFD packets.

·           In IRF mode, the packet-filter forwarding-layer route outbound command can cause the switch to discard sFlow packets. To avoid this problem, configure an advanced ACL rule by using the rule [ rule-id ] permit udp destination-port range eq udp-port command to permit sFlow packets. The udp-port is the port number of the sFlow collector and defaults to 6343. For information about sFlow, see Network Management and Monitoring Configuration Guide.

undo rule rule-id [ counting | time-range ] *

View

Ethernet frame header ACL view

Default level

2: System level

Parameters

rule-id: Specifies a rule ID, in the range of 0 to 65534. If no rule ID is provided when you create an ACL rule, the system automatically assigns it a rule ID. This rule ID takes the nearest higher multiple of the numbering step to the current highest rule ID, starting from 0. For example, if the rule numbering step is 5 and the current highest rule ID is 28, the rule is numbered 30.

deny: Drops matching packets if the ACL rule is used for packet filtering. When the ACL is used for traffic classification, the processing of deny rules vary with feature modules. For example, if you use an ACL for classifying traffic in a QoS policy, the switch does not perform the traffic behavior associated with the traffic class for the packets that match a deny rule.

permit: Allows matching packets to pass if the rule is used for packet filtering. When the ACL is used for traffic classification, the traffic that matches a permit rule matches the class. For example, if you use an ACL for classifying traffic in a QoS policy, the switch performs the traffic behavior associated with the traffic class for the packets that match a permit rule.

cos vlan-pri: Matches an 802.1p priority. The vlan-pri argument can be a number in the range of 0 to 7, or in words, best-effort (0), background (1), spare (2), excellent-effort (3), controlled-load (4), video (5), voice (6), or network-management (7).

counting: Counts the number of times the IPv4 ACL rule has been matched.

dest-mac dest-addr dest-mask: Matches a destination MAC address range. The dest-addr and dest-mask arguments represent a destination MAC address and mask in H-H-H format.

lsap lsap-type lsap-type-mask: Matches the DSAP and SSAP fields in LLC encapsulation. The lsap-type argument is a 16-bit hexadecimal number that represents the encapsulation format. The lsap-type-mask argument is a 16-bit hexadecimal number that represents the LSAP mask. The switch does not support this keyword.

type protocol-type protocol-type-mask: Matches one or more protocols in the Ethernet frame header. The protocol-type argument is a 16-bit hexadecimal number that represents a protocol type in Ethernet_II and Ethernet_SNAP frames. The protocol-type-mask argument is a 16-bit hexadecimal number that represents a protocol type mask. For example, to match ARP, IPv4, or IPv6 packets, specify protocol-type protocol-type-mask as 0x0806 0xFFFF, 0x0800 0xFFFF, or 0x86DD 0xFFFF.

source-mac sour-addr source-mask: Matches a source MAC address range. The sour-addr argument represents a source MAC address, and the sour-mask argument represents a mask in H-H-H format.

time-range time-range-name: Specifies a time range for the rule. The time-range-name argument is a case-insensitive string of 1 to 32 characters. It must start with an English letter. If the time range is not configured, the system creates the rule; however, the rule using the time range can take effect only after you configure the timer range.

Description

Use the rule command to create or edit an Ethernet frame header ACL rule. You can edit ACL rules only when the match order is config.

Use the undo rule command to delete an Ethernet frame header ACL rule or some attributes in the rule. If no optional keywords are provided, you delete the entire rule. If optional keywords or arguments are provided, you delete the specified attributes.

By default, an Ethernet frame header ACL does not contain any rule.

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 all command.

Default level

2: System level

Parameters

rule-id: Specifies a rule ID, in the range of 0 to 65534. If no rule ID is provided when you create an ACL rule, the system automatically assigns it a rule ID. This rule ID takes the nearest higher multiple of the numbering step to the current highest rule ID, starting from 0. For example, if the rule numbering step is 5 and the current highest rule ID is 28, the rule is numbered 30.

deny: Drops matching packets if the ACL rule is used for packet filtering. When the ACL is used for traffic classification, the processing of deny rules vary with feature modules. For example, if you use an ACL for classifying traffic in a QoS policy, the switch does not perform the traffic behavior associated with the traffic class for the packets that match a deny rule.

permit: Allows matching packets to pass if the rule is used for packet filtering. When the ACL is used for traffic classification, the traffic that matches a permit rule matches the class. For example, if you use an ACL for classifying traffic in a QoS policy, the switch performs the traffic behavior associated with the traffic class for the packets that match a permit rule.

protocol: Matches protocol carried over IPv6. It can be a number in the range of 0 to 255, or in words, gre (47), icmpv6 (58), ipv6, ipv6-ah (51), ipv6-esp (50), ospf (89), tcp (6), or udp (17). Table 15 describes the parameters that you can specify regardless of the value that the protocol argument takes.

If the protocol argument takes tcp (6) or udp (17), set the parameters shown in Table 16.

Table 16 TCP/UDP-specific parameters for IPv6 advanced ACL rules

 

If the protocol argument takes icmpv6 (58), set the parameters shown in Table 17.

Description

Use the rule command to create or edit an IPv6 advanced ACL rule. You can edit ACL rules only when the match order is config.

Use the undo rule command to delete an entire IPv6 advanced ACL rule or some attributes in the rule. If no optional keywords are provided, you delete the entire rule. If optional keywords or arguments are provided, you delete the specified attributes.

By default, an IPv6 advanced ACL does not contain any rule.

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.

Related commands: acl ipv6, display ipv6 acl, step, and time-range.

Parameters

rule-id: Specifies a rule ID, in the range of 0 to 65534. If no rule ID is provided when you create an ACL rule, the system automatically assigns it a rule ID. This rule ID takes the nearest higher multiple of the numbering step to the current highest rule ID, starting from 0. For example, if the rule numbering step is 5 and the current highest rule ID is 28, the rule is numbered 30.

deny: Drops matching packets if the ACL rule is used for packet filtering. When the ACL is used for traffic classification, the processing of deny rules vary with feature modules. For example, if you use an ACL for classifying traffic in a QoS policy, the switch does not perform the traffic behavior associated with the traffic class for the packets that match a deny rule.

permit: Allows matching packets to pass if the rule is used for packet filtering. When the ACL is used for traffic classification, the traffic that matches a permit rule matches the class. For example, if you use an ACL for classifying traffic in a QoS policy, the switch performs the traffic behavior associated with the traffic class for the packets that match a permit rule.

counting: Counts the number of times the IPv6 ACL rule has been matched.

fragment: Applies the rule only to non-first fragments. A rule without this keyword applies to both fragments and non-fragments.

logging: Logs matching packets. The keyword supports only the packet filter function.

source { ipv6-address prefix-length | ipv6-address/prefix-length | any }: Matches a source IP address. The ipv6-address and prefix-length arguments represent a source IPv6 address and address prefix length in the range of 1 to 128. The any keyword represents any IPv6 source address.

time-range time-range-name: Specifies a time range for the rule. The time-range-name argument takes a case-insensitive string of 1 to 32 characters. It must start with an English letter. If the time range is not configured, the system creates the rule; however, the rule using the time range can take effect only after you configure the timer range.

vpn-instance vpn-instance-name: Applies the rule to packets in a VPN. The vpn-instance-name argument takes a case-sensitive string of 1 to 31 characters. If no VPN instance is specified, the rule applies to non-VPN packets. The switch does not support this option.

Description

Use the rule command to create or edit an IPv6 basic ACL rule. You can edit ACL rules only when the match order is config.

Use the undo rule command to delete an entire IPv6 basic ACL rule or some attributes in the rule. If no optional keywords are provided, you delete the entire rule. If optional keywords or arguments are provided, you delete the specified attributes.

By default, an IPv6 basic ACL does not contain any rule.

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.

2: System level

Parameters

rule-id: Specifies a rule ID, in the range of 0 to 65534. If no rule ID is provided when you create an ACL rule, the system automatically assigns it a rule ID. This rule ID takes the nearest higher multiple of the numbering step to the current highest rule ID, starting from 0. For example, if the rule numbering step is 5 and the current highest rule ID is 28, the rule is numbered 30.

deny: Drops matching packets if the ACL rule is used for packet filtering. When the ACL is used for traffic classification, the processing of deny rules vary with feature modules. For example, if you use an ACL for classifying traffic in a QoS policy, the switch does not perform the traffic behavior associated with the traffic class for the packets that match a deny rule.

permit: Allows matching packets to pass if the rule is used for packet filtering. When the ACL is used for traffic classification, the traffic that matches a permit rule matches the class. For example, if you use an ACL for classifying traffic in a QoS policy, the switch performs the traffic behavior associated with the traffic class for the packets that match a permit rule.

ipv4: Specifies that the offset starts 20 bytes after the beginning of the IPv4 header.

ipv6: Specifies that the offset starts 40 bytes after the beginning of the IPv6 header. Only EC and EF cards support this keyword.

l2: Specifies that the offset starts two bytes before the Layer 3 header.

l4: Specifies that the offset starts 20 bytes after the Layer 4 header.

rule-string: Defines a match pattern in hexadecimal format. Its length must be a multiple of two.

rule-mask: Defines a match pattern mask in hexadecimal format. Its length must be the same as that of the match pattern. A match pattern mask is used for ANDing the selected string of a packet.

offset: Offset in bytes after which the match operation begins.

&<1-8>: Specifies that up to eight match patterns can be defined in the ACL rule.

counting: Counts the number of times the IPv4 ACL rule has been matched.

time-range time-range-name: Specifies a time range for the rule. The time-range-name argument takes a case-insensitive string of 1 to 32 characters. It must start with an English letter. If the time range is not configured, the system creates the rule; however, the rule using the time range can take effect only after you configure the timer range.

Description

Use the rule command to create a user-defined ACL rule. You cannot edit a user-defined ACL rule. If you number the ACL rule the same as an existing rule in the ACL, the new rule overwrites the old one.

Use the undo rule command to delete an entire user-defined ACL rule.

By default, a user-defined ACL does not contain any rule.

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 all command.

2: System level

Parameters

rule-id: Specifies a rule number in the range of 0 to 65535. The specified rule can be one that has been created or not. If you specify no rule ID when adding a remark, the system automatically picks the rule ID that is the nearest higher multiple of the numbering step to the current highest rule ID. For example, if the rule numbering step is 5 and the current highest rule ID is 28, the system picks rule 30.

text: Specifies a remark, a case-sensitive string of 1 to 63 characters.

Description

Use the rule remark command to add a start or end remark for a range of rules that are created for the same purpose.

Use the undo rule remark command to delete the specified or all rule range remarks.

By default, no rule range remarks are configured.

A rule range remark always appears immediately above the specified rule. If the specified rule has not been created yet, the position of the comment in the ACL is as follows:

·           If the match order is config, the remark is inserted into the ACL in descending order of rule ID.

·           If the match order is auto, the remark is placed at the end of the ACL. After you create the rule, the remark appears above the rule.

To display rule range remarks in an ACL, use the display this or display current-configuration.

When you delete rule range remarks, follow these guidelines:

·           If neither rule-id nor text is specified, all rule range remarks are removed.

·           Use the undo rule remark text command to remove all remarks that are the same as the text argument.

·           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.

Default level

2: System level

Parameters

step-value: ACL rule numbering step, in the range of 1 to 20.

Description

Use the step command 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. For example, if there are five rules numbered 5, 10, 13, 15, and 20, changing the step from 5 to 2 causes the rules to be renumbered 0, 2, 4, 6 and 8.

Use the undo step command to restore the default.

The default rule numbering step is 5. After you restore the default numbering step by the undo step command, the rules are renumbered in steps of 5.

Default level

2: System level

Parameters

time-range-name: Specifies a time range name. The name is a case-insensitive string of 1 to 32 characters. It must start with an English letter and to avoid confusion, cannot be all.

start-time to end-time: Specifies a periodic statement. Both start-time and end-time are in hh:mm format (24-hour clock), and each value is in the range of 00:00 to 23:59. The end time must be greater than the start time.

days: Specifies the day or days of the week (in words or digits) on which the periodic statement is valid. If you specify multiple values, separate each value with a space, and make sure that they do not overlap. These values can take one of the following forms:

·           A digit in the range of 0 to 6, respectively for Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday.

·           A day of a week in words, sun, mon, tue, wed, thu, fri, and sat.

·           working-day for Monday through Friday.

·           off-day for Saturday and Sunday.

·           daily for the whole week.

from time1 date1: Specifies the start time and date of an absolute statement. The time1 argument specifies the time of the day in hh:mm format (24-hour clock). Its value is in the range of 00:00 to 23:59. The date1 argument specifies a date in MM/DD/YYYY or YYYY/MM/DD format, where MM is the month of the year in the range of 1 to 12, DD is the day of the month with the range depending on MM, and YYYY is the year in the calendar in the range of 1970 to 2100. If not specified, the start time is 01/01/1970 00:00 AM, the earliest time available in the system.

to time2 date2: Specifies the end time and date of the absolute time statement. The time2 argument has the same format as the time1 argument, but its value is in the range of 00:00 to 24:00. The date2 argument has the same format and value range as the date1 argument. The end time must be greater than the start time. If not specified, the end time is 12/31/2100 24:00 PM, the maximum time available in the system.

Description

Use the time-range command to configure a time range.

Use the undo time-range command to delete a time range or a statement in the time range.

By default, no time range exists.

You can create multiple statements in a time range. Each time statement can take one of the following forms:

·           Periodic statement in the start-time to end-time days format. A periodic statement recurs periodically on a day or days of the week.

·           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. For example, to create a time range that is active from 08:00 to 12:00 on Monday between January 1, 2010 00:00 and December 31, 2010 23:59, use the time-range test 08:00 to 12:00 mon from 00:00 01/01/2010 to 23:59 12/31/2010 command.

The active period of a time range is calculated as follows:

1.      Combining all periodic statements

2.      Combining all absolute statements

3.      Taking the intersection of the two statement sets as the active period of the time range

You can create a maximum of 256 time ranges, each with a maximum of 32 periodic statements and 12 absolute statements.

Related commands: display time-range.
