RMON-MIB
Functions Overview
RMON-MIB is used to monitor the data traffic of a network section or the whole network. This MIB contains many tables, such as etherStatsTable, historyControlTable, etherHistoryTable, alarmTable, eventTable, and logTable.
The OID of the root object is iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1).rmon(16).

The following figure shows the relationship between RMON-MIB tables:
Description of MIB Tables
etherStatsTable
This table is the RMON Ethernet statistics table. This table records the basic statistics of each monitored subnet. Currently, one statistics row corresponds to one Ethernet port.

On one interface, only one etherStatsTable row can be created.
When creating a row, you must set the value of etherStatsStatus to valid or createRequest. After successful operation, a new statistics row is created, with etherStatsStatus as valid. If you set the value of etherStatsStatus to createRequest when creating a row, a new statistics row is created, with etherStatsStatus as underCreation. When creating a row, you must configure all mandatory objects. You must set the proper value for etherStatsStatus. It is mandatory. If you do not set the value for this object, a new statistics row is created, with etherStatsStatus as underCreation. When creating a user, you may not set the value of etherStatsOwner. In this case, the default value is null.
Modification Restriction
You can modify the value of etherStatsDataSource only when the value of etherStatsStatus is not valid.
You can modify the value of etherStatsOwner if the row exists. When the value of etherStatsStatus changes to valid or underCreation, you need to verify the validity of the interface.
Deletion Restriction
If you set the value of etherStatsStatus to invalid, the row is deleted from the table.
Access Restriction
The entries in this table can be read without restriction.
