Chapter 7 Configuring STP and RSTP on the ML-Series Card

Verifying and Monitoring STP and RSTP Status

Configuring the Forwarding-Delay Time for a Bridge Group

Beginning in privileged EXEC mode, follow these steps to configure the forwarding-delay time for a bridge group:

 

Command

Purpose

Step 1

 

 

ML_Series# configure

Enters global configuration mode.

 

terminal

 

Step 2

 

 

ML_Series(config)# bridge

Configures the forward time of a VLAN. The forward delay is the

 

bridge-group-number

number of seconds a port waits before changing from its

 

forward-time seconds

spanning-tree learning and listening states to the forwarding state.

 

 

 

 

For seconds, the range is 4 to 200; the default is 15.

Step 3

 

 

ML_Series(config)# end

Returns to privileged EXEC mode.

 

 

 

To return the switch to its default setting, use the no bridge bridge-group-numberforward-timeseconds command. The number for seconds should be the same number as configured in the original command.

Configuring the Maximum-Aging Time for a Bridge Group

Beginning in privileged EXEC mode, follow these steps to configure the maximum-aging time for a bridge group:

 

Command

Purpose

Step 1

 

 

ML_Series# configure

Enters global configuration mode.

 

terminal

 

Step 2

 

 

ML_Series(config)# bridge

Configures the maximum-aging time of a bridge group. The

 

bridge-group-number max-age

maximum-aging time is the number of seconds a switch waits

 

seconds

without receiving spanning-tree configuration messages before

 

 

 

 

attempting a reconfiguration.

 

 

For seconds, the range is 6 to 200; the default is 20.

Step 3

 

 

ML_Series(config)# end

Returns to privileged EXEC mode.

 

 

 

To return the switch to its default setting, use the no bridge bridge-group-numbermax-ageseconds command. The number for seconds should be the same number as configured in the original command.

Verifying and Monitoring STP and RSTP Status

To display the STP or RSTP status, use one or more of the privileged EXEC commands in Table 7-6.

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.
