6.3 Time Based Access Lists
6.3.3 Sample applications and configurations
The example in Figure denies HTTP traffic on Monday through Friday between the hours of 8:00 am and 6:00 pm on IP. The example allows UDP traffic on Saturday and Sunday from noon to 8:00 pm only.

The example in Figure configures an access list named northeast, which references a time range named xyz. The access list and time range together permit traffic on Ethernet interface 0 starting at 12:00 noon on January 1, 2001 and going forever.

The example in Figure permits UDP traffic until noon on December 31, 2000. After that time, UDP traffic is no longer allowed out Ethernet interface 0.

The example from Figure permits UDP traffic out Ethernet interface 0 on weekends only, from 8:00am on January 1, 1999 to 6:00 pm on December 31, 2001.
Lab Activity    
  The Denver office needs to control what interesting traffic will bring up the ISDN connection during only open hours. Last month they received a bill for $729.00 for ISDN service. You will setup a time-range extended ACL and apply it to the dialer group and the BRI interface so that the link will only be operational during business hours.
