Chapter 13 SNMP

13.8.1 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.

13.8.1 Remote Monitoring

The ONS 15600 incorporates RMON to allow network operators to monitor Ethernet facility performance and events. Software R7.0 and later 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.

13.8.2 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:

•cMediaIndependentTable—Standard, RFC 3273; the proprietary extension of the HC-RMON MIB used for reporting statistics

•cMediaIndependentHistoryTable—Proprietary MIB used to support history

13.8.2.1Row Creation in MediaIndependentTable

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

13.8.2.2 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)

13.8.3HC-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 this support. All of these elements are accessible by any third-party SNMP client having RFC 3273 support.

ONS 15600 specifications

Cisco Systems ONS 15600 is a highly versatile optical networking platform designed to meet the demands of modern telecommunications and data services. This multiservice edge platform supports various transmission mediums and offers a wide array of features that enable efficient data transport. Ideal for service providers and large enterprises, the ONS 15600 is engineered to provide scalable and reliable optical transport solutions.

One of the notable features of the ONS 15600 is its capability to support multiple protocols, including SONET/SDH, Ethernet, OTN, and legacy TDM services. This flexibility allows users to tailor their networks according to specific service requirements while ensuring interoperability with existing infrastructure. The platform is designed to facilitate seamless service migration, accommodating both legacy and next-generation services.

The modular architecture of the ONS 15600 enhances its scalability. It allows for easy expansion by incorporating additional line cards or interface modules without requiring significant downtime. This modularity ensures that service providers can evolve their networks over time, responding to increasing bandwidth demands and new service offerings with ease.

Incorporating advanced technologies, the ONS 15600 employs Dense Wavelength Division Multiplexing (DWDM), significantly increasing the capacity of fiber networks by allowing multiple signals to be transmitted simultaneously over a single optical fiber. This capability helps to optimize fiber utilization and reduce operational costs. In addition, the platform supports Optical Transport Network (OTN) for improved error detection and correction, contributing to higher reliability and performance.

Another key characteristic of the ONS 15600 is its robust management capabilities. The platform can be managed through Cisco's Optical Networking Manager (ONM), providing a centralized interface for network configuration, monitoring, and troubleshooting. This enhances operational efficiency and minimizes downtime, allowing service providers to focus on delivering quality services to their customers.

The ONS 15600 also prioritizes security, offering various features like encryption and access control to safeguard sensitive data during transmission. With its combination of scalability, flexibility, and security, the Cisco ONS 15600 stands out as a reliable choice for organizations looking to enhance their optical networking capabilities while meeting the evolving demands of the digital landscape. Its commitment to quality and performance makes it a cornerstone of modern optical networks.
