Operation Manual – ACL
H3C S7500 Series Ethernet Switches
Note:
source-mac-mask and dest-mac-mask represent the MAC address masks. For
example, if you want to specify a MAC address range from 0011-0011-0000 to
0011-0011-00ff, you can specify ffff-ffff-ff00 as the MAC address mask. The mask can
be all Fs, representing the host address.
To define the CoS, you can directly input a value ranging from 0 to 7, or input a keyword
listed in the following table.

In the case that you specify the rule ID when defining a rule:
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 the auto keyword specified, the rules of the ACL cannot be
edited. In this case, the system will prompt errors when you execute the rule
command.
If the rule corresponding to the specified rule ID does not exist, you will create and
define a new rule.
The content of a modified or newly created rule must not be identical with the
content of any existing rule; otherwise the rule modification or creation will be
failed, and the system will prompt that the rule already exists.
If you do not specify a rule ID, you will create and define a new rule, and the system will
assign an ID for the rule automatically.
