acl
Syntax
acl number acl-number [ name acl-name ] [ match-order { auto | config } ]
undo acl { all | name acl-name | number acl-number }
View
System view
Default level
2: System level
Parameters
number acl-number: Specifies the number of an IPv4 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
name acl-name: Assigns a name for the IPv4 ACL for easy identification. The acl-name argument takes a case insensitive string of 1 to 32 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 the 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.
all: Deletes all IPv4 ACLs.
Description
Use the acl command to create an IPv4 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.
By default, no ACL exists.
You can assign a name for 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
[Sysname] acl number 2000
[Sysname-acl-basic-2000]
# Create IPv4 basic ACL 2001 with the name flow, and enter its view.

rule (Ethernet frame header ACL view)
Syntax
rule [ rule-id ] { deny | permit } [ cos vlan-pri | dest-mac dest-addr dest-mask | { lsap lsap-type lsap-type-mask | type protocol-type protocol-type-mask } | source-mac sour-addr source-mask | time-range time-range-name ] *
undo rule rule-id [ fragment | time-range ]*
View
Ethernet frame header ACL view
Default level
2: System level
Parameters
rule-id: Specifies a rule ID, which ranges from 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: Denies matching packets.
permit: Allows matching packets to pass.
cos vlan-pri: Matches an 802.1p priority. The vlan-pri argument can be a number in the range 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).
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.
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.
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 specific 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 will fail.
To view rules in an ACL and their rule IDs, use the display acl all command.
Related commands: acl, display acl and step.

Parameters
rule-id: Specifies a rule ID, which ranges from 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: Denies matching packets.
permit: Allows matching packets to pass.
protocol: Protocol carried by IPv4. It can be a number in the range 0 to 255, or in words, gre (47), icmp (1), igmp (2), ip, ipinip (4), ospf (89), tcp (6), or udp (17). Table 6 describes the parameters that you can specify regardless of the value that the protocol argument takes.

Description
Use the rule command to create or edit an IPv4 advanced ACL rule. You can edit ACL rules only when the match order is config.
Use the undo rule command to delete an entire IPv4 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 specific attributes.
By default, an IPv4 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 will fail.
To view rules in an ACL and their rule IDs, use the display acl all command.
Related commands: acl, display acl, step, and time-range.

2: System level
Parameters
step-value: ACL rule numbering step, which ranges from 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.
Related commands: display acl and display acl ipv6.

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 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 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 ranges from 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.
