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.

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.

The “depth-first” order is described as follows:

l The “depth-first” ordering of rules in IP ACLs (including basic ACLs and advanced ACLs) is implemented based on the lengths of the source IP address/mask and the destination IP address/mask. The rule with the longest masks is first matched, and then comes the rule with the second longest masks, and so on. In the ordering, the lengths of the source IP addresses/masks are compared first; if the source IP address masks have the same length, the lengths of the destination IP address masks are compared. For example, the rule with the source IP address mask being 255.255.255.0 precedes the rule with the source IP address mask being 255.255.0.0 in the match order.

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.

fragment: Specifies that the ACL rule applies to other types of packets besides those that are not the first fragments.

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

time-range: Deletes 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. 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 rule identified by the rule-id argument already exists, the settings specified in the rule command overwrite the corresponding settings of the existing rule. And the existing settings remain unchanged if the corresponding settings are not specified in the 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.

undo rule rule-id

View

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.

time-range time-name: Specifies a time range within which the ACL rule is valid.

& Note:

Note the following when setting the offset argument.

l All the packets processed internally in a switch carry VLAN tags with them. A VLAN tag occupies four bytes of space.

l With the VLAN VPN function not enabled, a packet processed internally in a switch carries only one VLAN tag.

l With the VLAN VPN function enabled, a switch inserts another VLAN tag to the packets it processed, making the packets traveling across the network with two VLAN tags carried.

Description

Use the rule command to define an ACL rule.

Use the undo rule command to remove an ACL rule.

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.

& Note:

When setting the offset for a user-defined ACL, remember that you need to count two VLAN tags in no matter whether or not the packet is a tagged packet or an untagged packet. To filter 0800 packets using a user-defined ACL, you need to set the offset to 20.

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

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

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

days-of-the-week: Day of the week when the 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 a time range, in the form of hh:mm MM/DD/ YYYY. The start-time start-date and end-time end-date argument jointly define a period in which the special time range takes effect.

to end-time end-date: Specifies the end date of a time range, in the form of hh:mm MM/DD/ YYYY. The start-time start-date and end-time end-date argument jointly define a period in which the special time range takes effect.

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 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 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.
