The command accepts the optional time-range parameter. The time-range
parameter allows imposing a time limitation on the IP ACL rule as defined by
the parameter time-range-name. If a time range with the specified name does
not exist, and the IP ACL containing this ACL rule is applied to an interface
or bound to a VLAN, then the ACL rule is applied immediately. If a time
range with the specified name exists, and the IP ACL containing this ACL
rule is applied to an interface or bound to a VLAN, then the ACL rule is
applied when the time-range with a specified name becomes active. The ACL
rule is removed when the time-range with a specified name becomes inactive.
An implicit deny all condition is added by the system after the last MAC or
IP/IPv6 access group if no route-map is configured on the interface.
Every permit/deny rule that does not have a rate-limit parameter is assigned a
counter. If counter resources become exhausted, a warning is issued and the
rule is applied to the hardware without the counter.
If a permit|deny clause is entered with the same sequence number as an
existing rule, an error is displayed and the existing rule is not updated with
the new information.

The command is enhanced to accept the optional time-range parameter. The
time-range parameter allows imposing a time limitation on the MAC ACL
rule as defined by the parameter time-range-name. If a time range with the
