lsap lsap-type lsap-type-mask: Matches the DSAP and SSAP fields in LLC encapsulation. The
lsap-type argument is a hexadecimal number that represents the encapsulation format. The value
range for the lsap-type argument is 0 to ffff. The lsap-type-mask argument is a hexadecimal number
that represents the LSAP mask. The value range for the lsap-type-mask argument is 0 to ffff.
source-mac source-address source-mask: Matches a source MAC address range. The
source-address argument represents a source MAC address, and the sour-mask argument
represents a mask in the 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 time range. For more information about time range, see ACL and QoS
Configuration Guide.
Usage guidelines
Within an ACL, the permit or deny statement of each rule must be unique. If the 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.
To view the existing Layer 2 ACL rules, use the display acl mac all command.
The rule ID is required in the undo rule rule-id command.
If you do not specify optional parameters, the undo rule rule-id command deletes the entire rule. If
you specify optional parameters, the undo rule-id rule command deletes the specified attributes.
The undo rule { deny | permit } command can only be used to delete the entire rule. You must
specify all the attributes of the rule for the command.
The counting keyword in this command enables match counting specific to rules, and the
hardware-count keyword in the packet-filter command enables match counting for all rules in an
ACL.
