Using the SEHI100TX Hub View

To view device statistics at the Device, Module, or Port levels:

1.Display the Device, Module, or Port menu by clicking mouse button 3 in the appropriate area (refer to Figure 2-5, page 2-8).

2.Drag down to Statistics and then right to either General/Errors or Frames and release.

The Hub View begins counting the selected statistics when you open the window; counts will be cumulative until you use the Reset button or close the window.

NOTE

When a device is reset, statistics windows and/or statistics displays in the Hub View may display very large numbers for one polling interval. This is due to the resetting of the counters.

Because the SEHI100TX does not currently support Protocol counts, the Protocol Þelds in the Frames window will be grayed-out.

Note that the module statistics windows include the module number in the window title; the port statistics windows include the module and port numbers in the window title.

General/Error Statistics

The General/Errors statistics windows display the following Þelds:

Received Bytes

The number of bytes of data received by this device, module, or port since the window was last opened or reset.

Total Packets

The number of packets of all types received by this device, module, or port since the window was last opened or reset.

Avg Packet Size

The number of bytes per packet received by this device, module, or port since the window was last opened or reset. The average packet size is calculated by dividing the number of bytes received by the number of packets received.

Broadcast Packets

The number of broadcast packets received by this device, module, or port since the window was last opened or reset. Broadcast packets have a single address recognized by each station on the net: this address is designated in IP form as 255.255.255.255, or in MAC hexadecimal form as FF-FF-FF-FF-FF-FF. The ARP and RARP requests sent by bridges and routers are broadcast packets.
