number acl-number: Specifies the number of an existing access control list (ACL) or an ACL to be defined. ACL number identifies the type of an ACL as follows.

l An ACL number in the range 2000 to 2999 identifies a basic ACL.

l An ACL number in the range 3000 to 3999 identifies an advanced ACL. Note that 3998 and 3999 cannot be configured because they are reserved for cluster management.

l An ACL number in the range 4000 to 4999 identifies a layer 2 ACL.

match-order: Specifies the match order for ACL rules. Following two match orders exist.

l auto: Specifies to match ACL rules according to the depth-first rule.

l config: Specifies to match ACL rules in the order they are defined.

Note that the match-order keyword is not available to Layer 2 ACLs. The match order for layer 2 ACLs can only be config.

Description

Use the acl command to define an ACL and enter the corresponding ACL view.

Use the undo acl command to remove all the rules of the specified ACL or all the ACLs.

By default, ACL rules are matched in the order they are defined.

Only after the rules in an existing ACL are fully removed can you modify the match order of the ACL.

In ACL view, you can use the rule command to add rules to the ACL.

Related commands: rule.

Parameters

Parameters of the rule command

rule-id: ACL rule ID, in the range of 0 to 65534.

deny: Drops the matched packets.

permit: Permits the matched packets.

rule-string: ACL rule information, which can be a combination of the parameters described in Table 1-6.

Table 1-6 Parameters for basic IPv4 ACL rules

Parameter	Function	Description
source { sour-addr sour-wildcard \| any }	Specifies a source address.	The sour-addr sour-wildcard argument specifies a source IP address in dotted decimal notation. Setting the wildcard to a zero indicates a host address. The any keyword indicates any source IP address.
fragment	Indicates that the rule applies to fragments.	—
time-range time-name	Specifies the time range in which the rule takes effect.	time-name: specifies the name of the time range in which the rule is active; a string comprising 1 to 32 characters.

sour-wildcard is the complement of the wildcard mask of the source subnet mask. For example, you need to input 0.0.255.255 to specify the subnet mask 255.255.0.0.

Parameters of the undo rule command

rule-id: Rule ID, which must the ID of an existing ACL rule. You can obtain the ID of an ACL rule by using the display acl command.

fragment: Removes the settings concerning fragments in the ACL rule.

source: Removes the settings concerning source address in the ACL rule.

time-range: Removes the settings concerning time range in the ACL rule.

Description

Use the rule command to define an ACL rule.

Use the undo rule command to remove an ACL rule or specified settings of an ACL rule.

To remove an ACL rule using the undo rule command, you need to provide the ID of the ACL rule. If no other arguments are specified, the entire ACL rule is removed. Otherwise, only the specified information of the ACL rule is removed.

Note that:

l With the config match order specified for the basic ACL, you can modify any existent rule. The unmodified part of the rule remains. With the auto match order specified for the basic ACL, you cannot modify any existent rule; otherwise the system prompts error information.

l If you do not specify the rule-id argument when creating an ACL rule, the rule will be numbered automatically. If the ACL has no rules, the rule is numbered 0; otherwise, it is the maximum rule number plus one.

l The content of a modified or created rule cannot be identical with the content of any existing rule; otherwise the rule modification or creation will fail, and the system prompts that the rule already exists.

l With the auto match order specified, the newly created rules will be inserted in the existent ones by depth-first principle, but the numbers of the existent rules are unaltered.

from start-time start-date: Specifies the start date of an absolute time range, in the form of hh:mm MM/DD/YYYY or hh:mm YYYY/MM/DD. The start-time start-date and end-time end-date argument jointly define a period in which the absolute time range takes effect. If the start date is not specified, the time range starts from 1970/01/01 00:00.

to end-time end-date: Specifies the end date of an absolute time range, in the form of hh:mm MM/DD/YYYY or hh:mm YYYY/MM/DD. The start-time start-date and end-time end-date argument jointly define a period in which the absolute time range takes effect. If the end date is not specified, the time range ends at 2100/12/31 23:59.

Description

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

Use the undo time-range command to remove the specified or all time ranges.

Note that:

l If only a periodic time section is defined in a time range, the time range is active only when the system time is within the defined periodic time section. If multiple periodic time sections are defined in a time range, the time range is active only when the system time is within one of the periodic time sections.

l If only an absolute time section is defined in a time range, the time range is active only when the system time is within the defined absolute time section. If multiple absolute time sections are defined in a time range, the time range is active only when the system time is within one of the absolute time sections.

l If both a periodic time section and an absolute time section are defined in a time range, the time range is active only when the periodic time range and the absolute time range are both matched. Assume that a time range defines an absolute time section from 00:00 January 1, 2004 to 23:59 December 31, 2004, and a periodic time section from 12:00 to 14:00 every Wednesday. This time range is active only when the system time is within 12:00 to 14:00 every Wednesday in 2004.

Examples

# Define an absolute time range that is active from 12:00 January 1, 2000 to 12:00 January 1, 2001.
