Chapter 17 CE-Series Ethernet Cards

CE-MR-6 Ethernet Card

SONET synchronous transport signal (STS). When the payload reaches the destination node, the process is reversed and the data is transmitted from the 10/100/1000 Mbps Ethernet ports in the destination CE-MR-6 card onto the Ethernet cable and data network. The POS process is covered in detail in Chapter 6, “Configuring POS on the ML-Series Card.”

The CE-MR-6 card supports ITU-T G.707-based standards. It allows a soft reset, which is errorless in most cases. During the soft reset, if there is a provisioning change, or if the firmware is replaced during a software upgrade process, the reset is equivalent to a hard reset. For more information on a soft reset of a CE-MR-6 card using Cisco Transport Controller (CTC), refer to the

Cisco ONS 15310 Procedure Guide.

CE-MR-6 Ethernet Features

The Ethernet interface of the CE-MR-6 card comprises six front-end Small Form-factor Pluggable (SFP) slots. For each slot, the interface speed and media type is determined by the installed SFP module. The SFP slots support 10 Mbps, 100 Mbps, and 1000 Mbps (Gigabit Ethernet) operation. The SFP modules supporting the intended rate can be copper (10/100/1000 Mbps) or optical (100/1000 Mbps). SFP modules are offered as separate orderable products for flexibility. For SFP details, refer to the

Cisco ONS 15310 Reference Manual or Installing the GBIC, SFP, SFP+, XFP, CXP, and CFP Optical Modules in Cisco ONS Platforms. Ethernet Ports 1 through 6 each map to a POS port with a corresponding number. The console port on the CE-MR-6 card is not functional.

The CE-MR-6 card forwards valid Ethernet frames without modifying it over the SONET network. Information in the headers is not affected by encapsulation and transport. IEEE 802.1Q information travels through the process unaffected.

The CE-MR-6 supports jumbo frames with MTU sizes of 64 to 9600 bytes.

The CE-MR-6 card discards certain types of erroneous Ethernet frames rather than transport them over SONET. Erroneous Ethernet frames include corrupted frames with CRC errors and undersized frames that do not conform to the minimum 64-byte length, or oversized frames greater than 9600 bytes Ethernet standard.

Note Many Ethernet attributes are also available through the network element (NE) defaults feature. For more information on NE defaults, refer to the “Network Element Defaults” appendix in the Cisco ONS 15310 Reference Manual.

Autonegotiation, Flow Control, and Frame Buffering

On the CE-MR-6 card, Ethernet link auto negotiation is on by default when the duplex or speed of the port is set to auto. The user can also set the link speed, duplex, selective auto negotiation, and flow control manually under the card-level Provisioning tab in CTC.

The CE-MR-6 card supports selective auto negotiation on the Ethernet ports. If selective auto negotiation is enabled, the port attempts to auto negotiate only to a specific speed and duplex. The link will come up if both the speed and duplex of the attached auto negotiating device matches that of the port. You cannot enable selective auto negotiation if either the speed or duplex of the port is set to auto.

The CE-MR-6 card supports IEEE 802.3x flow control and frame buffering to reduce data traffic congestion. Flow control is on by default.

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.
