Configuring Basic Acl - 3Com 4210 9-Port Configuration Manual

Note that:
If only a periodic time section is defined in a time range, the time range is active only when the
system time is within the defined periodic time section. If multiple periodic time sections are defined
in a time range, the time range is active only when the system time is within one of the periodic time
sections.
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/28/2000 to 15:00 Jan/28/2004

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 section
The source IP addresses based on which the ACL filters packets are determined.
