Chapter 14 Configuring Resilient Packet Ring on the ML-Series Card

Configuring RPR

 

Command

Purpose

Step 4

 

 

Router(config-if)# carrier-delay msec

(Optional) Sets the carrier delay time. The default setting

 

milliseconds

is 200 msec, which is optimum for SONET protected

 

 

circuits.

 

 

Note The default unit of time for setting the carrier

 

 

delay is seconds. The msec command resets the

 

 

time unit to milliseconds.

Step 5

 

 

Router(config-if)# pos trigger defect

(Optional) Configures a trigger to bring down the POS

 

ber_sd-b3

interface when the SONET bit error rate exceeds the

 

 

threshold set for the signal degrade alarm. Bringing the

 

 

POS interface down initiates the RPR wrap.

 

 

This command is recommended for all RPR POS

 

 

interfaces, since excessive SONET bit errors can cause

 

 

packet loss on RPR traffic.

 

 

Note This command should not be used when a Cisco

 

 

ONS 15310 is part of the ring. It may cause

 

 

inconsistent RPR wrapping.

Step 6

 

 

Router(config-if)# no shutdown

Enables the POS port.

Step 7

 

 

Router(config-if)# interface pos 1

Enters the interface configuration mode to configure the

 

 

second POS interface that you want to assign to the SPR.

Step 8

 

 

Router(config-if)# encapsulation lex

Sets POS interface encapsulation as LEX (default). RPR

 

 

on the ML-Series card requires LEX encapsulation.

Step 9

 

 

Router(config-if)# spr-intf-id

Assigns the POS interface to the SPR interface. The

 

shared-packet-ring-number

shared packet ring number must be 1 (the same shared

 

 

packet ring number that you assigned in Step 3), which is

 

 

the only shared packet ring number that you can assign

 

 

to the SPR interface.

Step 10

 

 

Router(config-if)# carrier-delay msec

(Optional) Sets the carrier delay time. The default setting

 

milliseconds

is 200 milliseconds, which is optimum for SONET

 

 

protected circuits.

Step 11

 

 

Router(config-if)# pos trigger defect

(Optional) Configures a trigger to bring down the POS

 

ber_sd-b3

interface when the SONET bit error rate exceeds the

 

 

threshold set for the signal degrade alarm. Bringing the

 

 

POS interface down initiates the RPR wrap.

 

 

This command is recommended for all RPR POS

 

 

interfaces since excessive SONET bit errors can cause

 

 

packet loss on RPR traffic.

Step 12

 

 

Router(config-if)# no shutdown

Enables the POS port.

Step 13

 

 

Router(config-if)# end

Exits to privileged EXEC mode.

Step 14

 

 

Router# copy running-config

(Optional) Saves the configuration changes to NVRAM.

 

startup-config

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.
