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 ACL 3998 and ACL 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.

l An ACL number in the range 5000 to 5999 identifies a user-defined ACL.

match-order: Specifies the match order for the ACL rules of the ACL. This keyword is not available to Layer 2 ACLs or user-defined ACLs. Following two match orders exist.

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

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

all: Specifies to remove all the ACLs.

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 an ACL or all the ACLs.

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

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

Rules of an ACL can be matched in one of the following orders.

l Configured order: ACL rules are matched in the order they are defined.

l Automatic order: ACL rules are matched according to the “depth-first” rule.

With the depth-first rule adopted, the rules of an ACL are matched according to:

1) Protocol range. The range for IP is 1 to 255 and those of other protocols are their protocol numbers. The smaller the protocol range, the higher the priority.

2) Range of source IP address. The smaller the source IP address range (that is, the longer the mask), the higher the priority.

3) Range of destination IP address. The smaller the destination IP address range (that is, the longer the mask), the higher the priority.

4) Range of Layer 4 port number, that is, of TCP/UDP port number. The smaller the range, the higher the priority.

If rule A and rule B are the same in all the four ACEs (access control elements) above, and also in their numbers of other ACEs to be considered in deciding their priority order, the weighting principles will be used in deciding their priority order, as listed below.

l Each ACE is given a fixed weighting value. This weighting value and the value of the ACE itself will jointly decide the final matching order.

l The weighting values of ACEs rank in the following descending order: DSCP, ToS, ICMP, established, precedence, fragment.

l A fixed weighting value is deducted from the weighting value of each ACE of the rule. The smaller the weighting value left, the higher the priority.

l If the number and type of ACEs are the same for multiple rules, then the sum of ACE values of a rule determines its priority. The smaller the sum, the higher the priority.

You can use the match-order keyword to specify whether to use the configured order or “depth-first” order (rules with smaller ranges are matched first) to match rules. If neither match orders are specified, the configured match order will be adopted.

You cannot modify the match order for an ACL once you have specified it, unless you remove all the rules of the ACL and define new rules in the desired order.

The rules of an ACL are matched in a specific order only when the ACL is referenced by software for data filtering and traffic classification.

To remove an ACL rule using the undo rule command, you need to provide the ID of the ACL rule. You can obtain the ID of an ACL rule by using the display acl command.

When you define an ACL rule using the rule command with the rule-id argument provided,

l If the ACL is created with the config keyword specified and the rule identified by the rule-id argument exists, the settings specified in the rule command overwrite the counterparts of the existing rule (other settings of the rule remain unchanged). If the ACL is created with the auto keyword specified, the rules cannot be edited. In this case, the system prompts errors when you execute the rule command.

l If the ACL rule identified by the rule-id argument does not exist, you will create a new ACL rule.

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

If you do not specify the rule-id argument when creating an ACL rule, the ACL rule will be numbered automatically.

User-defined ACL view

Parameter

rule-id: ID of an ACL rule.

rule-string: User-defined ACL rule string. It must be an even hexadecimal number comprising 2 to 160 characters.

rule-mask: User-defined mask of the ACL rule. It must be an even hexadecimal number containing 2 to 160 hexadecimal characters and be of the same length as that of the rule-string argument. This argument is used to perform the logical AND operations with packets.

offset: Mask offset of the rule. It specifies a position in packets, from which the logical AND operation is to be performed. It ranges from 0 to 79 (in bytes). Note that the maximum value becomes one byte less when the rule-string (and rule-mask) argument has two more characters. For example, when rule-string and rule-mask contains two characters respectively, the maximum value of offset is 79 bytes; when the former contains four characters respectively, the maximum value of offset is 78 bytes, and so on.

&<1-8>: At most eight rules can be defined at one time.

1.1.12 time-range

Syntax

time-range time-name { start-time to end-time days-of-the-week [ from start-time start-date ] [ to end-time end-date ] | from start-time start-date [ to end-time end-date ] | to end-time end-date }

undo time-range { name time-name [ start-time to end-time days-of-the-week [ from start-time start-date ] [ to end-time end-date ] | from start-time start-date [ to end-time end-date ] | to end-time end-date ] | all }

View

System view

Parameter

time-name: Name of a time range, used as the identifier of a time range.

start-time: Start time of a periodic time range, in the form of hh:mm.

end-time: End time of a periodic time range, in the form of hh:mm.

days-of-the-week: Day of the week when the periodic time range is active. You can provide this argument in one of the following forms.

l Numeral (0 to 6)

l Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday

l Working days (Monday through Friday)

l Off days (Saturday and Sunday)

l Daily, namely everyday of the week

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 the earliest time that the system can represent.

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.

all: Removes all the time ranges.

Description

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

Use the undo time-range command to remove a time range.

The time range defined by using the time-range command can include absolute time sections and periodic time sections. The start-time and end-time days-of-the-week argument jointly define a periodic time section, while the start-time start-date and end-time end-date argument jointly define an absolute time section.

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.

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.

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.

If you include any argument undo time-range command, the system will removes only the content specified by the argument from the time range.

Example

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