5. nat protocol

Syntax:

nat protocols

Description:

The nat protocols command lists the application level gateways (ALGs) provided in the current image in order to support particular higher-level protocols, and the port or ports, which each ALG monitors

Example

>nat protocols

Name Port/IP protocol ftp 21/tcp

6. nat sessions

Syntax:

nat sessions <i/f> [all summary]

Description:

The nat sessions command displays a list of currently active NAT sessions on the interface <i/f>. In this context, a session is a pair of source IP addresses and port numbers (and corresponding new port number) that NAT regards as one side of an active connection. For each TCP or UDP session active, the source and destination IP address and port number, and the local port number and the age of the session, are printed.

The all option causes the sessions command to print out information on every session, including sessions, which have timed out. Normally the sessions command only shows active sessions (those which have not timed out). The summary command does not

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.
