#### Displaying Throughput Statistics

  The DLCI Statistics window, associated with an individual DLCI, provides the user with physical Layer 2 Throughput statistics collected on Frame Delay traffic passing across the DLCI.
  To open a DLCI Statistics window:
  1 Make sure that the Unit Detail window's DLCIs tab has been clicked.
  2 Position the mouse arrow over the DLCI entry, listed in the Unit Detail window's DLCIs tab, whose statistics you wish to view, and click the right mouse button.
  3 Select DLCI Statistics... from the list of pull-down menu options.
  This action will cause a window, corresponding to your DLCI selection, to be displayed. Examples of Statistic windows, for a DLCI seen off the DTE port and a DLCI seen off the Network port.
  Note: The window values displayed in parentheses represents the difference (delta) between values obtained during the previous polling interval and the current interval. The buttons located at the bottom of each DLCI Statistics window are described in the following paragraphs.
  Stop/Start - Clicking this button will update (refresh) the information contained in the DLCI Statistics window.
  Done - Clicking this button will close the DLCI Statistics window.

#### DLCI Throughput Statistics

  1. In Octets ~ Number of octets (bytes) which have been received on this DLCI.
  2. Out Octets ~ Number of octets (bytes) which have been transmitted on this DLCI.
  3. In Frames ~ Number of frames which have been received on this DLCI.
  4. Out Frames ~ Number of frames which have been transmitted on this DLCI.
  5. In FECN Frames ~ Number of frames which have been received on this DLCI with the Forward Explicit Congestion Notification (FECN) flag bit set.
  6. In BECN Frames ~ Number of frames which have been received on this DLCI with the Backward Explicit Congestion Notification (FECN) flag bit set.
  7. In DE Frames ~ Number of frames which have been received on this DLCI with the Discard Eligibility (DE) bit set.
  8. Out DE Frames ~ Number of frames which have been received on this DLCI with the Discard Eligibility (DE) bit set.
  9. In Throughput ~ Number of bit/Sec received on this DLCI during the current interval sample.
  10. Out Throughput ~ Number of bit/Sec transmitted on this DLCI during the current interval sample.
  11. CIR ~ Committed Information Rate (CIR) indicated in LMI messages for this DLCI.
  12. Uptime ~ The total cumulative time (days, hours, minutes, and seconds) that the DLCI has been available to carry traffic.
  13. Downtime ~ The total cumulative time (days, hours, minutes, and seconds) that the DLCI has been unavailable to carry traffic.
  14. Creation Time ~ The running time (day, hour, minuet, and second) from when the DLCI was first detected. The detect time will never reset (only increment) unless statistic are cleared. This statistic is not available as a protocol filter for Long Term collection.
  15. Last Change Time ~ The running time (day, hour, minuet, and second) from when the DLCI became active. This time will change each time the DLCI goes down and then becomes active once again. This statistic is not available as a protocol filter for Long Term collection.
