Chapter 16 Identifying Traffic with Access Lists
Scheduling Extended Access List Activation
The text can be up to 100 characters in length. You can enter leading spaces at the beginning of the text.
Trailing spaces are ignored.
For example, you can add remarks before each ACE, and the remark appears in the access list in this
location. Entering a dash (-) at the beginning of the remark helps set it apart from ACEs.
hostname(config)# access-list OUT remark - this is the inside admin address
hostname(config)# access-list OUT extended permit ip host 209.168.200.3 any
hostname(config)# access-list OUT remark - this is the hr admin address
hostname(config)# access-list OUT extended permit ip host 209.168.200.4 any
Scheduling Extended Access List Activation
You can schedule each ACE to be activated at specific times of the day and week by applying a time
range to the ACE. This section includes the following topics:
• Adding a Time Range, page 16-18
•
Applying the Time Range to an ACE, page 16-19
Adding a Time Range
To add a time range to implement a time-based access list, perform the following steps:
Step 1 Identify the time-range name by entering the following command:
hostname(config)# time-range name
Step 2
Specify the time range as either a recurring time range or an absolute time range.
Multiple periodic entries are allowed per time-range command. If a time-range command has both
absolute and periodic values specified, then the periodic commands are evaluated only after the
absolute start time is reached, and are not further evaluated after the absolute end time is reached.
•
Recurring time range:
hostname(config-time-range)# periodic
days-of-the-week time
to [
days-of-the-week
]
time
You can specify the following values for days-of-the-week :
–
monday , tuesday , wednesday , thursday , friday , saturday , and sunday .
– daily
–
weekdays
– weekend
The time is in the format hh : mm . For example, 8:00 is 8:00 a.m. and 20:00 is 8:00 p.m.
• Absolute time range:
hostname(config-time-range)# absolute start time date [ end time date ]
The time is in the format hh : mm . For example, 8:00 is 8:00 a.m. and 20:00 is 8:00 p.m.
The date is in the format day month year ; for example, 1 january 2006 .
