Viewing Chassis Information 2-9
Using the STS16-20 Chassis View
Displaying MIBs and MIB Components
Like most networking devices, the STS16-20 draws its functionality from a
collection of proprietary MIBs, and IETF RFCs. The MIB data is organized into a
series of Òcomponents,Ó which is a logical grouping of MIB data with each group
controlling a deÞned set of objects. There is no one-to-one correspondence
between MIBs and MIB components. A single MIB component might contain
objects from several different proprietary MIBs and RFCs.
The Chassis Manager window (Figure 2-4) is a read-only window that displays
the MIBs and the MIB components Ñ and, therefore, the functionality Ñ
supported by the currently monitored device.
To open the Chassis Manager window:
1. Click on Help in the Chassis View menu bar to access the Help menu.
2. Click on MIBs Supported. The Chassis Manager window, Figure 2-4, will
appear.

Viewing Hardware Descriptions
Menu options available at the device and port levels provide speciÞc information
about the physical characteristics of the STS16-20 and its ports.
Viewing the Device Type
The Device Type window displays a hardware description of the device.
To open the Device Type window:
1. Click on Device in the Chassis View menu bar to access the Device menu.
2. Click on Device Type. A Device Type window, similar to the one shown in
Figure 2-5, will appear.
The MIBs which provide the
functionality for the STS16-20
— both proprietary and IETF
RFCs — are listed here.
The MIB Components are
listed here. Note, there is no
one-to-one correspondence
between MIBs and MIB
Components.
