Chapter 6 Configuring POS on the ML-Series Card

Configuring the POS Interface

 

Command

Purpose

Step 3

 

 

Router(config-if)# [no] pos mode gfp

Sets the framing mode employed by the ONS

 

[fcs-disabled]

Ethernet card for framing and encapsulating data

 

 

packets onto the SONET transport layer. Valid

 

 

framing modes are:

 

 

HDLC—A common mechanism employed in

 

 

framing data packets for SONET. HDLC is

 

 

not a keyword choice in the command. The no

 

 

form of the command sets the framing mode

 

 

to Cisco HDLC.

 

 

GFP (default)—The ML-Series card supports

 

 

the frame mapped version of generic framing

 

 

procedure (GFP-F).

 

 

GFP-F with a 32-bit CRC, also referred to as

 

 

frame check sequence (FCS), is enabled by

 

 

default. The optional FCS-disabled keyword

 

 

disables the GFP-F 32-bit FCS.

 

 

The FCS-disabled keyword is not available when

 

 

setting the framing mode to Cisco HDLC.

 

 

Note CRC-under-HDLC framing is restricted to

 

 

a 32-bit size and cannot be disabled.

 

 

Note The GFP-F FCS is compliant with ITU-T

 

 

G.7041/Y.1303

Step 4

 

 

Router(config-if)# no shutdown

Restarts the shutdown interface.

Step 5

 

 

Router(config)# end

Returns to privileged EXEC mode.

Step 6

 

 

Router# copy running-config startup-config

(Optional) Saves configuration changes to

 

 

NVRAM.

 

 

 

Configuring POS Interface Encapsulation Type Under GFP-F Framing

To configure the encapsulation type for a 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).

ONS 15310-CL, ONS 15310-MA, Cisco ONS 15310-MA specifications

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.
