Chapter22 Configuring Network Securi ty with ACLs
Configuring ACLs
Beginning in privileged EXEC mode, follow these steps to configure a time-range parameter for an
ACL:
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
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 time-range time-range-name Identify the time-range by a meaningful name (for example, workhours),
and enter time-range configuration mode. The name cannot contain a
space or quotation mark and must begin with a letter.
Step3 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. 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.
Step4 end Return to privileged EXEC mode.
Step5 show time-range Verify the time-range configuration.
Step6 copy running-config startup-config (Optiona l) Save your entries in the configuration file.
