Chapter 27 Configuring Network Security with ACLs Configuring IP ACLs 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 for company holidays 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_2003 Switch(config-time-range)# absolute start 00:00 1 Jan 2003 end 23:59 1 Jan 2003 Switch(config-time-range)# exit Switch(config)# time-range thanksgiving_2003 Switch(config-time-range)# absolute start 00:00 27 Nov 2003 end 23:59 28 Nov 2003 Switch(config-time-range)# exit Switch(config)# time-range christmas_2003 Switch(config-time-range)# absolute start 00:00 24 Dec 2003 end 23:50 25 Dec 2003 Switch(config-time-range)# end Switch# show time-range time-range entry: christmas_2003 (inactive) absolute start 00:00 24 December 2003 end 23:50 25 December 2003 time-range entry: new_year_day_2003 (inactive) absolute start 00:00 01 January 2003 end 23:59 01 January 2003 time-range entry: thanksgiving_2000 (inactive) absolute start 00:00 22 November 2003 end 23:59 23 November 2003 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_2003 Switch(config)# access-list 188 deny tcp any any time-range thanskgiving_2003 Switch(config)# access-list 188 deny tcp any any time-range christmas_2003 Switch(config)# access-list 188 permit tcp any any time-range workhours Switch(config)# end Switch# show access-lists Extended IP access list 188 deny tcp any any time-range new_year_day_2003 (inactive) deny tcp any any time-range thanskgiving_2003 (active) deny tcp any any time-range christmas_2003 (inactive) permit tcp any any time-range workhours (inactive) This example uses named ACLs to permit and deny the same traffic. Switch(config)# ip access-list extended deny_access Switch(config-ext-nacl)# deny tcp any any time-range new_year_day_2003 Switch(config-ext-nacl)# deny tcp any any time-range thanksgiving_2003 Switch(config-ext-nacl)# deny tcp any any time-range christmas_2003 Switch(config-ext-nacl)# exit Switch(config)# ip access-list extended may_access Switch(config-ext-nacl)# permit tcp any any time-range workhours Switch(config-ext-nacl)# end Switch# show ip access-lists Extended IP access list deny_access deny tcp any any time-range new_year_day_2003 (inactive) deny tcp any any time-range thanksgiving_2003 (inactive) deny tcp any any time-range christmas_2003 (inactive) Extended IP access list may_access permit tcp any any time-range workhours (inactive) 78-16156-01 Catalyst 3560 Switch Software Configuration Guide 27-17
