Configuring VLANs

C H A P T E R 5

This chapter explains VLANs in detail and provides configuration instructions and examples.

VLANs: Virtual Local Area Networks (VLANs) are commonly used to split up groups of network users into manageable broadcast domains, to create logical segmentation of workgroups, and to enforce security policies among each logical segment. With multiple VLANs on an adapter, a server with a single adapter can have a logical presence on multiple IP subnets. By default, 128 VLANs can be defined for each VLAN-aware adapter on your server. However, this number can be increased by changing the system parameters.

If your network does not require multiple VLANs, you can use the default configuration, in which case no further configuration is necessary.

Note – If you change any of the VLAN configuration parameters, you must reboot the system before the changes take effect. If you make changes and do not reboot, you may experience configuration problems.

Overview of VLANs

VLANs enable you to split your physical LAN into logical subparts, providing an essential tool for increasing the efficiency and flexibility of your network.

GigaSwift Ethernet Adapter specifications

The Sun Microsystems GigaSwift Ethernet Adapter is a high-performance network interface card that was designed to provide advanced connectivity solutions for enterprise environments. Launched in the early 2000s, this adapter caters to the increasing demands for speed and efficiency in networking, especially amidst the rise of data-intensive applications.

One of the standout features of the GigaSwift Ethernet Adapter is its capability to support gigabit Ethernet technology, delivering data transfer rates of up to 1 Gbps. This allows organizations to boost their network throughput significantly, ensuring that bandwidth-intensive applications, such as video conferencing, online collaboration, and large file transfers, can be handled without significant lag or disruption.

The adapter utilizes a PCI-X interface, which enhances its performance compared to traditional PCI interfaces. This allows for higher bandwidth operations, making the GigaSwift suitable for servers and workstations that require robust connectivity. It is backward compatible with earlier Ethernet standards, which means it can seamlessly communicate with existing network infrastructures, preserving investments in legacy technologies.

Another critical characteristic of the GigaSwift Ethernet Adapter is its support for various networking protocols. It is designed to operate in diverse networking environments, supporting both full-duplex and half-duplex modes, which maximizes its efficiency in data transmission. This flexibility makes it an ideal choice for heterogeneous networks where different devices and standards coexist.

Furthermore, the adapter features advanced error detection and correction technologies, ensuring reliable transmission of data over the network. With features such as flow control and jumbo frame support, it enhances the efficiency and performance of large-scale data transfers.

The GigaSwift also comes equipped with diagnostic and management utilities, allowing network administrators to monitor the network performance effectively. This is crucial for identifying bottlenecks and optimizing network configurations to ensure peak operational efficiency.

Overall, the Sun Microsystems GigaSwift Ethernet Adapter is an essential tool for businesses looking to upgrade their networking infrastructure. Its combination of speed, versatility, and reliability allows enterprises to adopt next-generation networking solutions while maintaining compatibility with existing systems, ultimately contributing to a more robust and efficient IT environment.
