DHCP Client Configuration

9.3.2 Interface

interface " name" { declarations ... }

A client with more than one network interface may require different behaviour depending on which interface is being configured. All timing parameters and declarations other than lease and alias declarations can be enclosed in an interface declaration, and those parameters will then be used only for the interface that matches the specified name. Interfaces for which there is no interface declaration will use the parameters declared outside of any interface declaration, or the default settings

9.4 DHCP Options

The DHCP client supports only a subset of configuration options specified in [3]. However, this mechanism is extensible, allowing vendor-specific customization and possible support of more options in future. A DHCP client accepts the following information and uses it to configure the IP stack:

IP address

Subnet mask

The following would be useful, but are not supported in current software:

Default routers (one only)

Static routes

These are less useful but it is possible they will be supported in future:

IP forwarding enable/disable

Default IP time-to-live (TTL)

Interface Maximum Transmission Unit (MTU)

Host name

The following are not configurable in the current IP core and are unlikely to be supported:

Non-local source routing enable/disable

Policy filters for non-local source routing

Maximum re-assembly size

Path MTU ageing timeout

MTU plateau table

All-subnets-MTU

Broadcast address flavour

Perform mask discovery

Be a mask supplier

Perform router discovery

Router solicitation address

Trailer encapsulation

ARP cache timeout

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.
