Creating a rule for a flow

To accommodate creating a rule for a flow, mapsRule accepts a flow name as

a value for the -group parameter. The following example illustrates the

structure.

switch246:FID24:admin> mapsrule --create check_crc2 -monitor crc -group MyFlow -t

min -op g -value 15 -action raslog -policy daily_policy2

Modifying a MAPS policy rule

You can modify only user-defined MAPS policy rules. You cannot modify the default MAPS policy

rules.

To modify a user-defined MAPS policy rule, complete the following steps.

1. Enter mapsRule --show rule_name to display the rules, so you can identify the rule you want to

modify.

2. Enter mapsRule --config followed by the parameters you are changing to modify the rule.

NOTE

You only need to specify the parameters you are changing. Any parameters you do not specify are

not changed.

3. Optional: Enter mapsRule --show to display the updated rule.

4. If the rule is included in the active policy you must re-enable the policy using mapsPolicy --enable

policy policy_name for the modified rule to take effect.

Changing one parameter

The following example changes the time base for a rule from minutes to hours.

switch:admin> mapsrule --show check_crc

Rule Data:

----------

RuleName: check_crc

Condition: critical_ports(crc/minute>5)

Actions: raslog

Policies Associated: daily_policy

switch:admin> mapsrule --config check_crc -timebase hour
