DAC ES Performance Screen Navigation
Select the required DAC ES from the Module menu.
On opening, the Performance Statistics lines are empty. To enable, click the Start
All button. Data aggregates from this point forward for as long as CT is logged
on, or until the Stop All or Clear All buttons are selected.
Error events are shown with red text.
Viewing other CT screens does not affect the aggregation of performance
statistics.
The Stop All button terminates the data aggregation, but leaves for viewing the
data collected / displayed to that point.
The Clear All button clears all data.
If the Node is powered off, reset or the DAC ES withdrawn during data capture, a
warning is displayed advising that collected data has been interrupted.
Table 15-3 describes each statistic.
Table 15-3. Description of DAC ES RMON Performance Statistics
Statistic Description
In Ucast Pkts The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were not addressed to a multicast
or broadcast address at this sub-layer.
In Broadcast Pkts The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a broadcast
address at this sub-layer.
In Multicast Pkts The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a multicast
address at this sub-layer. For a MAC layer protocol, this
includes both Group and Functional addresses.
HC In Octets The total number of octets received on the interface,
including framing characters. This object is a 64-bit version
of If In Octets.
In Discards The number of inbound packets which were chosen to be
discarded even though no errors had been detected to prevent
them being deliverable to a higher-layer protocol. One
possible reason for discarding such a packet could be to free
up buffer space.
