Chapter 17 CE-Series Ethernet Cards

CE-MR-6 Ethernet Card

Note Priority queuing has no effect when flow control is enabled (default) on the CE-MR-6. When flow control is enabled, a 6KB, single-priority, first-in first-out (FIFO) buffer fills, then a PAUSE frame is sent. This results in the packet ordering priority becoming the responsibility of the external device, which is buffering as a result of receiving the PAUSE flow-control frames.

Note Priority queuing takes effect only when there is congestion at the egress POS. For example, priority queuing has no effect when the CE-MR-6 card is provisioned with STS-3C circuits and the front-end is

100Mbps. The STS-3c circuit has more data capacity than Fast Ethernet, so CE-MR-6 buffering is not needed. Priority queuing only takes effect during buffering.

RMON and SNMP Support

The CE-MR-6 card features remote monitoring (RMON) that allows network operators to monitor the health of the network with a network management system (NMS). The CE-MR-6 card uses

ONG RMON. ONG RMON contains statistics, history, alarms, and events MIB groups from the standard RMON MIB as well as Simple Network Management Protocol (SNMP). A user can access RMON threshold provisioning through TL1 or CTC. For RMON threshold provisioning with CTC, see the Cisco ONS 15310 Procedure Guide and the Cisco ONS 15310 Troubleshooting Guide.

The following SNMP MIBs are supported by the CE-MR-6 card:

•RFC2819 -MIB

Cisco Systems has long been a leader in networking and telecommunications technology, and among its impressive lineup of products, the Cisco ONS 15310 series stands out as an essential solution for optical networking. This series includes models such as the ONS 15310-MA, ONS 15310-CL, and ONS 15310-CA, each designed to meet the diverse needs of service providers and enterprises seeking to enhance their optical transport networks.

The Cisco ONS 15310-MA is an advanced multi-service platform designed for metropolitan area networks. It facilitates the seamless transport of data, voice, and video over optical networks. One of its main features is its ability to support a variety of interfaces, including Ethernet, SONET/SDH, and Wavelength Division Multiplexing (WDM), allowing users to integrate multiple services into a single platform. Additionally, the ONS 15310-MA supports advanced traffic management and Quality of Service (QoS) features to prioritize critical applications and ensure consistent performance.

The ONS 15310-CL variant is tailored for more specific applications, providing enhanced capabilities aimed at delivering carrier-grade services. It features a robust architecture that accommodates high-capacity traffic without compromising reliability. This model emphasizes low power consumption and a compact design, making it suitable for deployment in space-constrained environments. The ONS 15310-CL also supports a wide range of optical interfaces, making it highly flexible for various network configurations.

In terms of technologies, the Cisco ONS 15310 series leverages Optical Transport Network (OTN) capabilities, providing high efficiency and greater bandwidth utilization. OTN technology enables efficient error correction and adds resilience to the network through its built-in protection mechanisms. Furthermore, the series supports seamless integration with existing IP/MPLS networks, creating a cohesive infrastructure as organizations evolve their networking requirements.

One of the defining characteristics of the ONS 15310 series is its focus on scalability. Network operators can start with a modest deployment and gradually expand capacity as demand grows. This adaptability is complemented by Cisco's comprehensive management and monitoring tools, providing operators with real-time insights into network performance and facilitating proactive management.

In conclusion, the Cisco ONS 15310-MA and ONS 15310-CL models represent sophisticated solutions for modern optical networks. With their versatile features, advanced technologies, and robust design, they empower service providers and enterprises to build resilient, high-capacity networks that meet the demands of today’s data-driven world.
