Chapter 6 Configuring POS on the ML-Series Card

Configuring the POS Interface

Configuring the POS Interface

The user can configure framing mode, encapsulation, and Cisco IOS SONET alarm reporting parameters through Cisco IOS.

Scrambling on the ONS 15310-CL and ONS 15310-MA ML-Series card is on by default and is not configurable. The C2 byte is not configurable. CRC-under-HDLC framing is restricted to 32-bit and is not configurable. CRC-under-GFP-F is restricted to 32-bit, but can be enabled (default) and disabled.

Note ML-Series card POS interfaces normally send PDI-P to the far end when the POS link goes down or RPR wraps. ML-Series card POS interfaces do not send PDI-P to the far end when PDI-P is detected, when RDI-P is being sent to the far end, or when the only defects detected are GFP LFD, GFP CSF, VCAT LOM, or VCAT SQM.

Configuring POS Interface Framing Mode

You can configure framing mode on an ML-100T-8 card through Cisco IOS. You cannot configure framing mode through CTC on the ML-100T-8 card.

Framing mode can be changed on a port by port basis. The user does not need to delete the existing circuits or reboot the ML-100T-8 card. On the ONS 15454 or ONS 15454 SDH ML-Series cards, the circuits must be deleted and the card must reboot for the framing mode to change.

To configure framing mode for the ML-Series card, perform the following steps, beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

Router(config)# interface pos number

Activates interface configuration mode to

 

 

configure the POS interface.

Step 2

 

 

Router(config-if)# shutdown

Manually shuts down the interface. Encapsulation

 

 

and framing mode changes on POS ports are

 

 

allowed only when the interface is shut down

 

 

(ADMIN_DOWN).

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.
