> # Configuring Delayed Traps

> The server.callhome.delayedtrap.enable property is added to section 9 Call Home in the server.properties configuration file. The property file can enable the DCNM-SAN server to use delayed traps instead of regular linkDown traps for EMC E-mail Home messages.

> ## Prerequisites

> To enable this feature, you need to turn on delayed traps at switch level, and then set the server.callhome.delayedtrap.enable property in the server.properties configuration file to true. By default, the server.callhome.delayedtrap.enable option is disabled and regular linkDown traps are used.

> ## Detailed Steps

> To enable delayed traps on switches running NX-OS Release 4.1(3) and later, follow these steps:

> 1. Expand Events and select SNMP Traps in the Physical Attributes pane.

> In the table above the map layout in DCNM-SAN, click the Delayed Traps tab.

> 2. Check the Enable check box for the switches on which you want to enable delayed traps.
> 3. Enter the timer value in the Delay column.
> 4. Click Apply to save your changes.

> Note If no value is entered, the default value of 4 minutes is used.

> To disable delayed traps, follow these steps:

> 1. Uncheck the Enable check box.
> 2. Click Apply.
