Configuring ACLs Chapter 29 Configuring Network Security with ACLs Step 3 Step 4 Step 5 Step 6 Command Purpose absolute [start time date] [end time date] or periodic day-of-the-week hh:mm to [day-of-the-week] hh:mm Specify when the function it will be applied to is operational. Use some combination of these commands; multiple periodic statements are allowed; only one absolute statement is allowed. If more than one absolute statement is configured, only the one configured last is executed. or periodic {weekdays | weekend | daily} hh:mm to hh:mm end Return to privileged EXEC mode. show time-range Verify the time-range configuration. copy running-config startup-config (Optional) Save your entries in the configuration file. To remove a configured time-range, use the no time-range time-range-name global configuration command. Repeat the steps if you have multiple items that you want operational at different times. This example shows how to configure time ranges for workhours and for company holidays and how 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_2000 Switch(config-time-range)# absolute start 00:00 1 Jan 2000 end 23:59 1 Jan 2000 Switch(config-time-range)# exit Switch(config)# time-range thanksgiving_2000 Switch(config-time-range)# absolute start 00:00 22 Nov 2000 end 23:59 23 Nov 2000 Switch(config-time-range)# exit Switch(config)# time-range christmas_2000 Switch(config-time-range)# absolute start 00:00 24 Dec 2000 end 23:50 25 Dec 2000 Switch(config-time-range)# end Switch# show time-range time-range entry: christmas_2000 (inactive) absolute start 00:00 24 December 2000 end 23:50 25 December 2000 time-range entry: new_year_day_2000 (inactive) absolute start 00:00 01 January 2000 end 23:59 01 January 2000 time-range entry: thanksgiving_2000 (inactive) absolute start 00:00 22 November 2000 end 23:59 23 November 2000 time-range entry: workhours (inactive) periodic weekdays 8:00 to 12:00 periodic weekdays 13:00 to 17:00 To apply a time range, you must reference it by name (for example, workhours) 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 time ranges and permits all TCP traffic during work hours. Switch(config)# access-list 188 deny tcp any any time-range new_year_day_2000 Switch(config)# access-list 188 deny tcp any any time-range thanskgiving_2000 Switch(config)# access-list 188 deny tcp any any time-range christmas_2000 Switch(config)# access-list 188 permit tcp any any time-range workhours Switch(config)# end 29-16 Catalyst 2950 and Catalyst 2955 Switch Software Configuration Guide 78-11380-10
