Chapter 5 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 5-1).

15310-CL, 15310-MA specifications

Cisco Systems has established itself as a leader in the networking domain, offering a wide array of solutions to meet the needs of modern businesses. Among its impressive product lineup are the Cisco 15310-CL and 15310-MA routers, designed to provide advanced network performance and reliability.

The Cisco 15310-CL is a versatile platform that primarily serves as a carrier-class router aimed at supporting high-speed data and voice services. It is built to handle the demands of large enterprises and service providers, offering a robust design that ensures maximum uptime and performance. One of its standout features is its modular architecture, which enables users to customize their configurations based on specific application needs. This scalability allows for future expansion without the need for a complete hardware overhaul.

Key technologies integrated into the Cisco 15310-CL include high-density Ethernet interfaces and a comprehensive suite of Layer 2 and Layer 3 protocol support. The device is capable of supporting multiple types of connections, including TDM, ATM, and Ethernet. This flexibility makes it an ideal choice for organizations that require seamless migration between various service types. Moreover, with features such as MPLS (Multiprotocol Label Switching) support and advanced Quality of Service (QoS) mechanisms, the router ensures that critical applications receive the necessary bandwidth and low latency required for optimal performance.

In contrast, the Cisco 15310-MA focuses on access solutions, providing a cost-effective entry point for businesses looking to enhance their network capabilities. It is well-suited for smaller offices or branch locations that need reliable connectivity without the expense and complexity associated with larger systems. The device supports a range of access methods and provides essential features like firewall capabilities, VPN support, and comprehensive security measures to protect sensitive data.

Both models benefit from Cisco's commitment to security and manageability, offering features like enhanced encryption protocols and user authentication mechanisms that help safeguard networks against threats. Additionally, they can be managed through Cisco’s intuitive software tools, simplifying configuration and monitoring tasks for IT administrators.

The Cisco 15310-CL and 15310-MA are ideal solutions for businesses seeking to enhance their network infrastructure, ensuring firms can keep pace with evolving technology demands while maintaining a focus on security and performance. Their combination of advanced features, modular capabilities, and robust support makes them valuable assets in the networking landscape.
