Creating a Trap Destination

You can create trap destinations from either the Network Workshop or the Device Workshop. From the Create Trap Destination dialog box, you can set default values and associate device parameters. There are two tabs in the Create Trap Destination dialog box: Default Values and Associated Devices.

• Default Values tab—From this tab, you set the default values to be used on the initial association of a trap destination with an E-series device. You can modify these values on a per-device level when you associate the destination host with an E-series device.
• Associated Devices tab—From this tab, you associate a trap destination with any E-series device's virtual router that does not yet have the maximum number of trap destinations associated with it. The Associated Device parameters are populated with the currently selected device from the device table. These values are not configurable.

• Add/Remove Devices dialog box—From this dialog box, you make selections of available devices and virtual routers that you want to associate with the trap destination. The Host Name, IP Address, UDP Port, Community Name, and Protocol Version parameters are populated with the currently selected trap destination values. These values are not configurable. The device trap parameters are populated with the values for the virtual router you select.

To create a trap destination:

1. From the Device-wide Explorer, click Trap Destinations.
2. Right-click, and click Create Trap Destinations.

The Create Trap Destination dialog box appears.

3. Set the trap destination parameters (Table 4).
