Chapter 6 Configuring POS on the ML-Series Card

Configuring the POS Interface

Configuring SONET Alarms

All SONET alarms are logged on the Cisco IOS CLI by default. But to provision or disable the reporting of SONET alarms on the Cisco IOS CLI, 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 report

Permits console logging of selected SONET alarms. Use the

 

{all encap pais plop ppdi

no form of the command to disable reporting of a specific

 

pplm prdi ptim puneq

alarm.

 

sd-ber-b3 sf-ber-b3}

 

 

 

 

 

The alarms are as follows:

 

 

•

all—All alarms/signals

 

 

•

encap—Path encapsulation mismatch

 

 

• pais—Path alarm indication signal

 

 

• plop—Path loss of pointer

 

 

• ppdi—Path payload defect indication

 

 

• pplm—Payload label, C2 mismatch

 

 

• prdi—Path remote defect indication

 

 

• ptim—Path trace identifier mismatch

 

 

• puneq—Path label equivalent to zero

 

 

• sd-ber-b3—PBIP BER in excess of SD threshold

 

 

• sf-ber-b3—PBIP BER in excess of SF threshold

Step 3

 

 

Router(config-if)# end

Returns to the privileged EXEC mode.

Step 4

 

 

Router# copy running-config

(Optional) Saves configuration changes to NVRAM.

 

startup-config

 

 

 

 

 

 

To determine which alarms are reported on the POS interface and to display the bit error rate (BER) thresholds, use the show controllers pos command, as described in the “Monitoring and Verifying POS” section on page 6-8.

Configuring SONET Delay Triggers

You can set path alarms listed as triggers to bring down the line protocol of the POS interface. When you configure the path alarms as triggers, you can also specify a delay for the triggers using the pos trigger delay command. You can set the delay from 200 to 2000 ms. If you do not specify a time interval, the default delay is set to 200 ms.

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.
