Topology Type
Indicates how the port is being used. The available types are:
¥ Station Ñ The port is receiving packets from no devices, a single device, or
two devices. Note that a port in station status may actually be connected to
multiple devices; station status simply indicates that no more than two devices
are currently active.
¥ Trunk Ñ The port is receiving packets from three or more devices; it may be
connected to a coax cable with multiple taps, or to a repeater or another MIM.
¥ Unknown Ñ The SEHI100TX cannot determine the topology status.
Checking Statistics
The Hub View can provide a summary of Ethernet statistics at the Device,
Module, and Port levels, as shown in Figure 2-10. The windows that display the
statistics contain the same statistical categories at each level.
