2 × (forwarddelay - 1) maxage

 

 

maxage 2 × (hellotime + 1)

 

 

Configuration saving saves this information. By default the forward

 

delay time is set to 15 seconds.

 

Example:

;Sets the forwarding

 

DSL bridge> spanning forwarddelay 10

 

 

delay to 10 seconds.

11. spanning hellotime

Syntax:

spanning hellotime [<time>]

Description:

Reads or sets the time in seconds, after which the spanning tree process sends notification of topology changes to the root bridge, and is used when the bridge is or is attempting to become the root bridge. The hello time may be any value between 1 and 10 and is also constrained by the forwarddelay and maxage times. The hello time may also be changed by SNMP command.

Configuration saving saves this information. By default the hello time is set to 2 seconds.

Example:

DSL bridge> spanning hellotime 5

;Sets the hello time

 

to 5 seconds

12. spanning maxage

Syntax:

spanning maxage [<time>]

Description:

Reads or sets the maximum age of received spanning tree protocol information before it is discarded, and is used when the bridge is or is attempting to become the root bridge. The maxage time may be any value between 6 and 40 and is also constrained by the forwarddelay and hellotime times. The maxage time may also be changed by SNMP command.

Configuration saving saves this information. By default the maxage time is set to 20 seconds.

Example:

DSL bridge> spanning maxage 6

;Sets the maxage

 

time to 6 seconds

Heritage specifications

IBM, or International Business Machines Corporation, is a global leader in technology and consulting, with a heritage that spans over a century. Established in 1911, IBM initially emerged from a merger of four companies, and it has since evolved into one of the most influential players in the tech industry.

One of the main features of IBM’s legacy is its commitment to innovation. The company has a long history of technological breakthroughs, including the development of the first programmable computer, the IBM 701, in the early 1950s. IBM has also been at the forefront of many pivotal technologies, including mainframe computers, which became central to large-scale enterprise computing. The System/360, introduced in 1964, revolutionized the industry by offering a compatible range of computers that could run the same software, a concept that helped define the standardization of computer systems.

IBM’s contributions to artificial intelligence, particularly through its Watson platform, are another hallmark of its heritage. Watson gained international fame for its success on the quiz show Jeopardy! in 2011, showcasing advanced natural language processing capabilities and machine learning techniques. This technology has since found applications in various fields, from healthcare to finance, significantly transforming data analysis.

Another key characteristic of IBM is its focus on research and development. With an impressive portfolio of patents, IBM consistently ranks among the top patent holders annually. Their research endeavors have led to significant advancements in quantum computing, with initiatives like the IBM Quantum Experience making quantum technologies accessible to developers and researchers.

Sustainability is also a priority for IBM, with programs aimed at promoting environmental responsibility. The company has committed to achieving net-zero greenhouse gas emissions by 2030, reflecting the growing importance of sustainability in technology practices.

In summary, IBM's heritage is characterized by a strong legacy of innovation, technological leadership, and a commitment to addressing contemporary challenges in business and society. From pioneering mainframe systems to leading the charge in AI and quantum computing, IBM continues to shape the future of technology while maintaining a visionary outlook towards a sustainable and inclusive digital world.
