13.9 Remote Monitoring

For security reasons, the SNMP proxy feature must be enabled at all receiving and transmitting NEs to
function. For instructions to do this, refer to the Cisco ONS 15600 Procedure Guide.
13.9 Remote Monitoring
The ONS 15600 incorporates RMON to allow network operators to monitor Ethernet facility
performance and events. Software Release R7.0 and later releases provide remote data communications
channel (DCC) monitoring using 64-bit RMON over the DCC to gather historical and statistical Ethernet
data. In general, ONS 15600 system RMON is based on the IETF-standard MIB RFC 2819 and includes
the following five groups from the standard MIB: Ethernet Statistics, History Control, Ethernet History,
Alarm, and Event.
Typical RMON operations, other than threshold provisioning, are invisible to the CTC user.
Note

13.9.1 64-Bit RMON Monitoring over DCC

The ONS 15600 DCC is implemented over the IP protocol, which is not compatible with Ethernet. The
system monitors Ethernet equipment history and statistics using RMON. RMON DCC monitoring (for
both IP and Ethernet) is also supported; it monitors the health of remote DCC connections.
RMON DCC contains two MIBs for DCC interfaces. They are:
•
•

13.9.1.1 Row Creation in MediaIndependentTable

The mediaIndependentTable is created automatically when the Ethernet facility is created on the
ONS 15600 ASAP card.

13.9.1.2 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:
•
•
•

13.9.2 HC-RMON-MIB Support

For the ONS 15600, the implementation of the high-capacity remote monitoring information 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
Cisco ONS 15600 Reference Manual, R8.0
