Cisco Systems 3130 User Manual

Beginning in privileged EXEC mode, follow these steps to configure a time-range parameter for an ACL:

Repeat the steps if you have multiple items that you want in effect at different times. 

To remove a configured time-range limitation, use the no time-range time-range-name global 
configuration command.

This example shows how to configure time ranges for workhours and to configure January 1, 2006, as a 
company holiday and to verify your configuration.

Switch(config)# time-range workhours

Switch(config-time-range)# periodic weekdays 8:00 to 12:00

Switch(config-time-range)# periodic weekdays 13:00 to 17:00

Switch(config-time-range)# exit

Switch(config)# time-range new_year_day_2006

Switch(config-time-range)# absolute start 00:00 1 Jan 2006 end 23:59 1 Jan 2006

Switch(config-time-range)# end

Switch# show time-range

time-range entry: new_year_day_2003 (inactive)

   absolute start 00:00 01 January 2006 end 23:59 01 January 2006

time-range entry: workhours (inactive)

   periodic weekdays 8:00 to 12:00

   periodic weekdays 13:00 to 17:00 

To apply a time range, enter the time-range name in an extended ACL that can implement time ranges. 
This example shows how to create and verify extended access list 188 that denies TCP traffic from any 
source to any destination during the defined holiday times and permits all TCP traffic during work hours.

Switch(config)# access-list 188 deny tcp any any time-range new_year_day_2006

Switch(config)# access-list 188 permit tcp any any time-range workhours

Switch(config)# end

Switch# show access-lists

Extended IP access list 188

   10 deny tcp any any time-range new_year_day_2006 (inactive)

   20 permit tcp any any time-range workhours (inactive) 

Enter global configuration mode.

time-range time-range-name

Assign a meaningful name (for example, workhours) to the time range to 
be created, and enter time-range configuration mode. The name cannot 
contain a space or quotation mark and must begin with a letter.

absolute [start time date] 
[end time date]

or 
periodic day-of-the-week hh:mm to 
[day-of-the-week] hh:mm

or 
periodic {weekdays | weekend | daily} 
hh:mm to hh:mm

Specify when the function it will be applied to is operational. 

You can use only one absolute statement in the time range. If you 
configure more than one absolute statement, only the one configured 
last is executed.

You can enter multiple periodic statements. For example, you could 
configure different hours for weekdays and weekends.

See the example configurations.

end 

Return to privileged EXEC mode.

Verify the time-range configuration.

(Optional) Save your entries in the configuration file.
