MAPS actions

The change in the CRC counter in the last minute is greater than 10.

For this condition, the threshold is “greater than 10”.

NOTE

MAPS conditions are applied on a per-port basis, not switch- or fabric-wide. For example, 20 ports

that each get 1 CRC counter would not trigger a “greater than 10” rule.

Time base

Time bases specify the time interval between two samples to be compared. You can set the time

base to day (samples are compared once a day), hour (samples are compared once an hour), or

minute (samples are compared every minute).

The time base affects the comparison of sensor-based data with user-defined threshold values.For

measures where the time base is not applicable, set the time base to “none”.

MAPS actions

When you create a rule, you associate an action for MAPS to take if the condition defined in the rule

evaluates to true.

Each rule can have one or more actions associated with it. For example, you can configure a rule to

issue a RASLog message and fence the port if the number of CRC errors on any E_Port is greater

than 20 per minute.

The global action settings on the switch take precedence over the actions defined in the rules.

For example, if the global action settings allow RASLog alerts, but do not allow port fencing, then in

the previous example, if the CRC threshold is reached, a RASLog message would be issued but the

port would not be fenced. To enable global actions, use mapsConfig --actions. For more details,

refer to “Enabling or disabling actions at a global level” on page 28. Refer to the Fabric OS

Command Reference for further details on using this command.

MAPS provides the following actions:

• RASLog messages

• SNMP traps

• E-mail alert

• Port fencing

• Switch critical

• Switch marginal

• SFP marginal
