Eem Policies - Cisco Nexus 5600 Series Configuration Manual

EEM Policies

• Policies—An event paired with one or more actions to troubleshoot or recover from the event.
EEM Policies
An EEM policy consists of an event statement and one or more action statements. The event statement defines
the event to look for as well as the filtering characteristics for the event. The action statement defines the
action EEM takes when the event occurs.
The following figure shows the two basic statements in an EEM policy.

You can configure EEM policies by using the CLI or a VSH script.
EEM gives you a device-wide view of policy management. You configure EEM policies on the supervisor,
and EEM pushes the policy to the correct module based on the event type. EEM takes any actions for a
triggered event either locally on the module or on the supervisor (the default option).
EEM maintains event logs on the supervisor.
Cisco NX-OS has a number of preconfigured system policies. These system policies define many common
events and actions for the device. System policy names begin with two underscore characters (__).
You can create user policies to suit your network. If you create a user policy, any actions in your policy occur
after EEM triggers any system policy actions that are related to the same event as your policy. To configure
a user policy, see
You can also override some system policies. The overrides that you configure take the place of the system
policy. You can override the event or the actions.
Use the show event manager system-policy command to view the preconfigured system policies and determine
which policies that you can override.
To configure an overriding policy, see
You should use the show running-config eem command to check the configuration of each policy. An
Note
override policy that consists of an event statement and no action statement triggers no action and no
notification of failures.
Your override policy should always include an event statement. An override policy without an event
statement overrides all possible events in the system policy.
