Cabletron Systems SEHI-22/24 Checking Statistics, Topology Type, 2-15, Using the SEHI Hub View

Using the SEHI Hub View

•Multi-Mode Fiber: ST EPIM

•Single-Mode Fiber: ST EPIM

Topology Type

Indicates how the port is being used. The available types are:

•Station—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—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 — The SEHI 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.
