> # EMC E-mail Home Delayed Traps

> DCNM-SAN can be configured to generate EMC E-mail Home XML e-mail messages. In SAN-OS Release 3.x or earlier, DCNM-SAN listens to interface traps and generates EMC E-mail Home e-mail messages. Link traps are generated when an interface goes to down from up or vice versa. For example, if there is a scheduled server reboot, the link goes down and DCNM-SAN generates an e-mail notification.

> Cisco NX-OS Release 4.1(3) provides the ability to generate a delayed trap so that the number of generated e-mail messages is reduced. This method filters server reboots and avoids generating unnecessary EMC E-mail Home e-mail messages. In NX-OS Release 4.1(3), users have the ability to select the current existing feature or this new delayed trap feature.
