Setting Forced Mode

This section describes how to set forced mode (not capable of auto- negotiation).

▼To select one of the five local transceiver capabilities and set the mode to forced mode

1.Select one of the following capabilities: adv_100T4_cap, adv_100fdx_cap, adv_100hdx_cap, adv_10fdx_cap, or adv_10hdx_cap, and set its value to 1.

If you select more than one of the local transceiver capabilities, the driver selects the one that is highest in the priority order (see the footnote from Table 3-5 on page 13).

2.Set the local transceiver capabilities advertised by the hardware to forced mode = 0, which is not capable of auto-negotiation: adv_autoneg_cap 0

Use the ndd utility as described in “Using the ndd Utility in Interactive Mode” on page 22.

Auto-Negotiation Mode

This section describes how to select at least one of the five local transceiver capabilities and set the mode to auto-negotiation.

▼To set the mode to auto-negotiation

1.Select at least one of the five capabilities (adv_100T4_cap,

adv_100fdx_cap, adv_100hdx_cap, adv_10fdx_cap, adv_10hdx_cap) that you want to advertise to the remote system, and set its value to 1.

2.Set the local transceiver capabilities advertised by the hardware to 1, the auto-negotiation setting: adv_autoneg_cap 1

Use the ndd utility as described in “Using the ndd Utility in Interactive Mode” on page 22.

Sun Microsystems, established in 1982, became a pioneering force in the realms of computing and technology. Initially founded by four Stanford University graduates, the company was built on innovative ideas and a vision to create powerful computing solutions. One of the standout features of Sun Microsystems was its commitment to open systems and network computing. Sun's early adoption of Unix operating systems significantly influenced the development of reliable and scalable systems.

One of the key technologies developed by Sun was the SPARC architecture. This scalable, high-performance RISC (Reduced Instruction Set Computer) architecture powered many of its servers and workstations, allowing for enhanced computing capabilities. SPARC systems were well-regarded for their performance efficiency and reliability, making them a popular choice for enterprise applications.

Sun also played a crucial role in software development. The introduction of the Java programming language in the mid-1990s revolutionized how developers approached cross-platform application development. With its tagline “Write Once, Run Anywhere,” Java enabled applications to run on various platforms without modification. This technology became foundational in web-based applications and enterprise solutions.

Another notable aspect of Sun Microsystems was its commitment to networking and storage solutions. The company developed robust server systems that catered to high-performance computing demands, supporting enterprises in managing vast amounts of data. Sun’s Network File System (NFS) allowed seamless file sharing across networks, which became a standard in many organizations.

The company was also a pioneer in providing various services and solutions for data centers, including virtualization and cloud computing approaches that preceded the wave of cloud services we see today. Their emphasis on innovative storage solutions and data management systems positioned them as industry leaders.

Though Sun Microsystems was acquired by Oracle Corporation in 2010, its technological legacy continues to shape the IT landscape. The contributions made by Sun in areas such as software development, hardware architecture, and open systems have left an indelible mark on the technology industry. The emphasis on openness and innovation laid the groundwork for many principles that guide modern computing, making Sun Microsystems an integral part of the history of technology.
