Figure 2-2. SEHI Hub View Device Menu

The Device menu lets you perform the following:

•Open the Device Status window

•Open the Repeater Status window

•Open the Polling Intervals window

•Open the Statistics windows

•Create device-level Pie Charts, Graphs and Meters

•Change the Port Display Form

•Launch the Link/Seg Traps application

•Launch the Redundancy application

•Launch the Source Addressing application

•Launch the Security application.

Note that the Device menu does not provide access to every application which is available to the SEHI; some information is only available from the Module or Port menus, and several applications can only be accessed either from the icon menu (if you are running under a network management platform) or from the command line (if you are running in stand-alone mode). See Chapter 1, Introduction to SPMA for the SEHI-22/24 and SEHI-32/34, for a complete list of applications available to the SEHI and how to access each one.
