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. For more information about time range, see ACL and QoS Configuration

Guide.

Usage guidelines

When an Ethernet frame header ACL with the lsap keyword specified is used for QoS traffic classification

or packet filtering, the lsap-type argument must be AAAA and the lsap-type-mask argument must be FFFF.

Otherwise, the ACL cannot be applied successfully.

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, the rule will not be created

or changed.

You can edit ACL rules only when the match order is config.

• If you do not specify any optional keywords, the undo rule command deletes the entire rule.

• If you specify optional keywords or arguments, the undo rule command deletes the specified

attributes.

To view rules in an ACL and their rule IDs, use the display acl all command.

Examples

# Create a rule in Ethernet frame header ACL 4000 to permit ARP packets and deny RARP packets.

<Sysname> system-view

[Sysname] acl number 4000

[Sysname-acl-ethernetframe-4000] rule permit type 0806 ffff

[Sysname-acl-ethernetframe-4000] rule deny type 8035 ffff
