Using Traffic Filters
117348-A Rev. A 1-11
Ranges
For each traffic filter criterion, you also specify the valid range, a series of target
values that apply to the criterion. For most criteria, you specify an address range.
There must be at least one target value for each criterion. The range can be just
one value or a set of values.
You enter a minimum and a maximum value to specify the range. For a range of
only one value, you enter only the minimum value; the Configuration Manager
automatically uses that value for both the minimum and maximum value.
For example, if the filter criteria is MAC Source Address, you must specify which
addresses you want the filter to examine. If you specify 0x0000A2000001 as the
minimum range value and 0x0000A2000003 as the maximum range value, the
router checks for packets with a MAC source address between 0x0000A2000001
and 0x0000A2000003, inclusive.
Actions
The filter action determines what happens to packets that match a filter criterion’s
ranges. You can apply the following actions to any traffic filter:
• Accept
The router processes any packet that matches the filter criteria and ranges.
• Drop
The router does not route any packet that matches the filter criteria and ranges.
• Log
For every packet that matches the filter criteria and ranges, the router sends an
entry to the system Events log. You can specify the Log action in combination
with other actions.
Note: Chapter 5 lists valid ranges for common traffic filter criteria and
explains how to specify some common address ranges.
Note: Specify the Log action only to record abnormal events; otherwise, the
Events log will fill up with filtering messages, leaving no room for critical log
messages.
