16.10.1.2 Row Creation in cMediaIndependentHistoryControlTable

SNMP row creation and deletion for the cMediaIndependentHistoryControlTable follows the same
processes as for the MediaIndependentTable; only the variables differ. In order to create a row, the
SetRequest PDU should contain the following:
• cMediaIndependentHistoryControlDataSource and its desired value
• cMediaIndependentHistoryControlOwner and its desired value
• cMediaIndependentHistoryControlStatus with a value of createRequest (2)
16.10.2 HC-RMON-MIB Support
For the ONS 15454, the implementation of the high-capacity remote monitoring info rmation base
(HC-RMON-MIB, or RFC 3273) enables 64-bit support of existing RMON tables. This support is
provided with the etherStatsHighCapacityTable and the etherHistoryHighCapacityTable. An additional
table, the mediaIndependentTable, and an additional object, hcRMONCapabilities, are also added for
this support. All of these elements are accessible by any third-party SNMP client should have the ability
to upload RFC 3273 SNMP MIB variables in the etherStatsHighCapacityTable,
etherHistoryHighCapacityTable, or mediaIndependentTable.
16.10.3 Ethernet Statistics RMON Group
The Ethernet Statistics group contains the basic statistics monitored for each subnetwork in a single table
called the etherStatsTable.

16.10.3.1 Row Creation in etherStatsTable

The SetRequest PDU for creating a row in this table contains all needed values to activate a table row in
a single operation as well as assign the status variable to createRequest. The SetRequest PDU OID)
entries must have an instance value, or type OID, of 0.
In order to create a row, the SetRequest PDU should contain the following:
• The etherStatsDataSource and its desired value
• The etherStatsOwner and its desired value (up to 32 characters)
• The etherStatsStatus with a value of createRequest (2)
The etherStatsTable creates a row if the SetRequest PDU is valid according to these rules. The SNMP
agent decides the value of etherStatsIndex when the row is created and this value changes when an
Ethernet interface is added or deleted; it is not sequentially allotted or contiguou sly numbered. A newly
created row will have an etherStatsStatus value of valid (1). If the etherStatsTable row already exists, or
if the SetRequest PDU values are insufficient or do not make sense, the SNMP agent returns an error
code.
Note EtherStatsTable entries are not preserved if the SNMP agent is restarted.
