Command Sets for Command Line Interface

3. device list

Syntax:

device list

Description:

This command lists all the devices that are currently attached to the bridge. It does not show the stored configuration (which can be seen with the config print command).

Example:

DSL bridge> device list

4. ethertype

Syntax:

ethertype [<port> anyippppoe]

Description:

This command enables filtering of Ethernet packets according to the ETHER_TYPE field in the header. Only packets of the type specified using this command will be sent on the port specified; packets of all types will always be received. By default, all bridge ports are set to “any”, which means that the type of the packet will never be checked. The meaning of the other options is as follows:

Option

Permitted ETHER_TYPE values

“ip”

0x0800

– IP

 

0x0806

– ARP

“pppoe”

0x8863, 0x8864 – PPP Over Ethernet (RFC 2516)

The port is specified as an integer, as displayed by the device list command. When using this command in the initbridge configuration file, ports are numbered in the order in which the device add commands are given, starting from 1.

If no arguments are given, the current settings for each port are displayed.

Example:

DSL bridge> ethertype 2 any

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.
