Brief Introduction to ACL 207
You can use the following command to set the time range by performing the
following configuration in the System View.
Tab le 224 Set the Absolute Time Range
When the start-time and end-time are not configured, it will be all the time for
one day. The end time shall be later than the start time.
When
end-time end-date
is not configured, it will be all the time from now to
the date which can be displayed by the system. The end time shall be later than
the start time.
Defining ACL The Switch 5500G-EI supports several types of ACL. This section introduces how
to define these ACLs.
Defining ACL by following the steps below:
1 Enter the corresponding ACL view.
2 Add a rule to the ACL.
You can add multiple rules to one ACL.
■ If a specific time range is not defined, the ACL will always function after
activated.
■ During the process of defining the ACL, you can use the rule command several
times to define multiple rules for an ACL.
■ If ACL is used to filter or classify the data transmitted by the hardware of the
Switch, the match order defined in the acl command will not be effective. If
ACL is used to filter or classify the data treated by the software of the Switch,
the match order of ACL’s sub-rules will be effective. Once the user specifies the
match-order of an ACL rule, he cannot modify it later.
■ The default matching-order of ACL is config, i.e. following the order as that
configured by the user.
Define Basic ACL
The rules of the basic ACL are defined on the basis of the Layer-3 source IP address
to analyze the data packets.
You can use the following command to define basic ACL.
Perform the following configuration in the corresponding view.
