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 under 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

bytes transmitted. “DE,” or Discard Eligible, refers to the data that is first
eligible to be discarded when network congestion occurs.

The Service Aware screen (Figure 3.35) provides a table showing these
filtered packet counts for up to 10 rules. This table indicates which Service
Aware filters are enabled or disabled, and shows the specific DLCI, IP
Address, and IP Port by which the IP traffic is filtered. In addition, this table
