Collision domain assignments
All hubs running at the same speed in the stack belong to the same
collision domain. In the example below, all devices (PCs, print
servers, and so on) connected to hubs 1 and 2 share 100 Mbps of
bandwidth. All devices connected to hubs 3 and 4 share 10 Mbps of
bandwidth.

The two collision domains don’t pass traffic to each other without
optional bridging equipment (see the Intel Express 10/100 Stackable
Hub User Guide that came with the hub for more information on
bridging options).
MIB identification
If you use a MIB browser, you can configure or view statistics for the
hub at three levels – by hub (chassis), module, or port. The MIB file
locations are listed on page 51.

The entire hub is called
the chassis.
The group of base ports on the
hubs are called modules. The
expansion slots are also modules.
