Figure 3.39 DLCI Statistics Screen
There are ninety-six 15-minute buckets (sampled every second) available for
DLCI statistics. If the unit is powered on at 01:00 PM, the first interval will
be completed at 01:15 PM; subsequent intervals would be completed at xx:30,
xx:45, xx:00 and xx:15. Interval 1 is always the latest (most recent) interval,
and interval 96 will always be the oldest.
The DLCI Statistics screen in the preceding figure shows a summary that
includes all 96 buckets. You can choose to see the statistics for any given
bucket by selecting the desired Period Index from the pull-down menu and
clicking the “Submit” button. Alternatively, you can display all intervals at
once by clicking the “All DLCI Intervals” button beneath the table. The MIB
(ipadv2.mib) describes each available statistic. “FDR” on the screen above
refers to Frame Delivery Ratio, which is the ration of successful frame
receptions to attempted frame transmissions. “DDR” refers to Data Delivery
Ratio or the ratio of successful payload bytes received to attempted payload
bytes transmitted. “DE,” or Discard Eligible, refers to the data that is first
eligible to be discarded when network congestion occurs.
DLCI Table Screen
Clicking the “DLCI Table” button on the DLCI Details screen will display a
table of all DLCIs (Figure 3.40) on a specific frame relay service along with
their state and alarm conditions.
