7.3.3 Configuring the ethernetStatsTable
EthernetStatsTable records traffic information that RMON collects on interfaces.
Context
Do as follows on the switch on which traffic statistics should be collected:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface { gigabitethernet | xgigabitethernet } interface-number
The interface view is displayed.
Step 3 Run:
rmon statistics entry-number [ owner owner-name ]
The ethernetStatsTable is configured.
To monitor the statistics of an interface on a device, a network administrator needs to create a
table entry for this interface and specify the interface OID, entry index, and entry state. The
network administrator can then read the corresponding entry to obtain the latest statistics.

7.3.4 Configuring the HistoryControlTable
HistoryControlTable provides the historical data management function. With this function, you
can sample traffic of a certain interface, set the maximum number of items to be saved and the
sampling interval, collect traffic statistics on the specific interface periodically, and save the
statistics to etherHistoryTable for future use.
Context
The history data management supports the setting of sampling, sampling interval, and saving
quantity for the traffic passing through a specified port. RMON periodically collects statistics
of the port and saves them to etherHistoryTable for future reference.
As recommended by the RMON specifications, each monitored interface should be configured
with more than two history control entries. One entry is sampled every 30 seconds while another
entry is sampled every 30 minutes.
The short sampling interval enables a monitor to probe the sudden changes of traffic modes, and
the long sampling interval is applicable if the interface status is relatively stable.
Currently, the S5700 reserves up to 10 pieces of the latest records for each history control entry.
NOTE
To reduce the effect on the performance of the system, the sampling interval of the history table should be
longer than 10 seconds, and the same port should not be configured with too many history control entries
and alarm entries.
