EEM Event Correlation

EEM Event Correlation
You can trigger an EEM policy based on a combination of events. First, you use the tag keyword to create
and differentiate multiple events in the EEM policy. Then using a set of boolean operators (and, or, andnot),
along with the count and time, you can define a combination of these events to trigger a custom action.

High Availability

Cisco NX-OS supports stateless restarts for EEM. After a reboot or supervisor switchover, Cisco NX-OS
applies the running configuration.

Virtualization Support

You configure EEM in the virtual device context (VDC) that you are logged into. By default, Cisco NX-OS
places you in the default VDC. You must be in this VDC to configure policies for module-based events.
Not all actions or events are visible in all VDCs. You must have network-admin or vdc-admin privileges to
configure policies.
See the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide for more information
on VDCs.
