Chapter 6 Configuring POS on the ML-Series Card

Monitoring and Verifying POS

To configure path alarms as triggers and specify a delay, perform the following steps beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

Router(config)# interface pos

Enters interface configuration mode and specifies the POS

 

number

interface to configure.

Step 2

 

 

Router(config-if)# pos trigger

Configures certain path defects as triggers to bring down the

 

defect {all ber_sf_b3 encap

POS interface. The configurable triggers are as follows:

 

pais plop ppdi pplm

• all—All link down alarm failures

 

prdi ptim puneq}

 

 

• ber_sd_b3—PBIP BER in excess of SD threshold

 

 

failure

 

 

• ber_sf_b3—PBIP BER in excess of SD threshold failure

 

 

(default)

 

 

• encap—Path Signal Label Encapsulation Mismatch

 

 

failure (default)

 

 

• pais—Path Alarm Indication Signal failure (default)

 

 

• plop—Path Loss of Pointer failure (default)

 

 

• ppdi—Path Payload Defect Indication failure (default)

 

 

• pplm—Payload label mismatch path (default)

 

 

• prdi—Path Remote Defect Indication failure (default)

 

 

• ptim—Path Trace Indicator Mismatch failure (default)

 

 

• puneq—Path Label Equivalent to Zero failure (default)

Step 3

 

 

Router(config-if)# pos trigger

Sets waiting period before the line protocol of the interface

 

delay millisecond

goes down. Delay can be set from 200 to 2000 ms. If no time

 

 

intervals are specified, the default delay is set to 200 ms.

Step 4

 

 

Router(config-if)# end

Returns to the privileged EXEC mode.

Step 5

 

 

Router# copy running-config

(Optional) Saves configuration changes to NVRAM.

 

startup-config

 

 

 

 

Monitoring and Verifying POS

Showing the outputs framing mode and concatenation information with the show controller pos [0 1] command (Example 6-1).

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.
