Configuring Basic Acl - 3Com 5500-EI PWR Install Manual

If only an absolute time section is defined in a time range, the time range is active only
when the system time is within the defined absolute time section. If multiple absolute
time sections are defined in a time range, the time range is active only when the system
time is within one of the absolute time sections.
If both a periodic time section and an absolute time section are defined in a time range,
the time range is active only when the periodic time range and the absolute time range
are both matched. Assume that a time range contains an absolute time section ranging
from 00:00 January 1, 2004 to 23:59 December 31, 2004, and a periodic time section
ranging from 12:00 to 14:00 on every Wednesday. This time range is active only when
the system time is within the range from 12:00 to 14:00 on every Wednesday in 2004.
If the start time is not specified, the time section starts from 1970/1/1 00:00 and ends
on the specified end date. If the end date is not specified, the time section starts from
the specified start date to 2100/12/31 23:59.
Configuration example
# Define a periodic time range that spans from 8:00 to 18:00 on Monday through Friday.
<Sysname> system-view
[Sysname] time-range test 8:00 to 18:00 working-day
[Sysname] display time-range test
Current time is 13:27:32 Apr/16/2005 Saturday
Time-range : test ( Inactive )
08:00 to 18:00 working-day
# Define an absolute time range spans from 15:00 1/28/2006 to 15:00 1/28/2008.
<Sysname> system-view
[Sysname] time-range test from 15:00 1/28/2006 to 15:00 1/28/2008
[Sysname] display time-range test
Current time is 13:30:32 Apr/16/2005 Saturday
Time-range : test ( Inactive )
From 15:00 Jan/28/2006 to 15:00 Jan/28/2008

Configuring Basic ACL

A basic ACL filters packets based on their source IP addresses.
A basic ACL can be numbered from 2000 to 2999.
Configuration prerequisites
To configure a time range-based basic ACL rule, you need to create the corresponding
time range first. For information about time range configuration, refer to
Time Range.
The source IP addresses based on which the ACL filters packets are determined.
