Glossary

TCP(TransmissionControlProtocol)  Anetworkprotocol for transmitting data that requires acknowledgement from the recipient of data sent.

TCP/IP (Transmission Control Protocol/Internet Protocol)  A set of instructions PCs use to communicate over a network.

Telnet  A user command and TCP/IP protocol used for accessing remote PCs.

TFTP (Trivial File Transfer Protocol)  A version of the TCP/IP FTP protocol that has no directory or password capability.

Throughput  The amount of data moved successfully from one node to another in a given time period.

Trunking  Link Aggregation. Optimizes port usage by linking a group of ports together to form a single trunk (aggregated groups).

TX Rate  Transmission Rate.

UDP (User Data Protocol)  Communication protocol that transmits packets but does not guarantee their delivery.

Upgrade  To replace existing software or firmware with a newer version.

Upload  To transmit a file over a network.

URL (Uniform Resource Locator)  The address of a file located on the Internet.

VLAN (Virtual Local Area Networks)  Logical subgroups that constitute a Local Area Network (LAN). This is done in software rather than defining a hardware solution.

WAN (Wide Area Network)  Networks that cover a large geographical area.

Wildcard Mask  Specifies which IP address bits are used, and which bits are ignored. A wild card mask of 255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that all the bits are important.

For example, if the destination IP address is 149.36.184.198 and the wildcard mask is 255.36.184.00, the first two bits of the IP address are used, while the last two bits are ignored.

Linksys SRW2048, SRW248G4, SRW2024, SRW224G4, SRW2016 manual Appendix D

SRW2016, SRW224G4, SRW2024, SRW2048, SRW248G4 specifications

The Linksys SRW2048 is a robust Layer 2 managed switch that caters to the networking needs of small to medium-sized businesses. Designed with performance and reliability in mind, it provides features that ensure optimal network efficiency and security.

One of the standout features of the SRW2048 is its 48 10/100/1000 Mbps Gigabit Ethernet ports, enabling high-speed data transfer and seamless connectivity for various devices within the network. This makes it ideal for environments with heavy data traffic, ensuring minimal latency and high performance.

The SRW2048 also supports advanced Layer 2 management features, including VLAN (Virtual Local Area Network) support, which allows users to segment the network into smaller, manageable sections. This is crucial for improving security and performance, as it reduces unnecessary traffic and potential broadcast storms. With a VLAN configuration, businesses can group users and devices based on function or department, ensuring efficient communication within teams.

In addition to VLAN capabilities, the Linksys SRW2048 incorporates Quality of Service (QoS) features. This technology prioritizes critical network traffic, such as voice over IP (VoIP) and video conferencing, ensuring that these applications receive the bandwidth they require for optimal performance. This is particularly beneficial for businesses that rely on real-time communication tools.

The switch also enhances security through features such as IEEE 802.1X port security, which ensures that only authorized users can access the network. The SRW2048 supports access control lists (ACLs), allowing administrators to set specific permissions for users and devices, further tightening security.

Linksys has also equipped the SRW2048 with a user-friendly web-based management interface, simplifying the process of configuring and monitoring network performance. This accessible interface allows IT personnel to quickly identify issues, manage traffic, and configure settings without extensive training.

Another notable characteristic of the Linksys SRW2048 is its robust build quality and reliability. With a metal chassis and fanless design, it maintains a low acoustic footprint and ensures passive cooling, making it suitable for office environments.

Overall, the Linksys SRW2048 is a feature-rich managed switch that combines advanced networking technologies, efficient performance, and security features to meet the diverse needs of modern businesses. Its scalability, manageability, and robust construction make it a valuable addition to any network infrastructure.
