DSL (Digital Subscriber Line) - An always-on broadband connection over traditional phone lines..

DSCP (DiffServ Code Point) - Provides a method of tagging IP packets with QoS priority information..

Dynamic IP Address - A temporary IP address assigned by a DHCP server..

EIGRP (Enhanced Interior Gateway Routing Protocol)

-Provides fast convergence, support for variable-length subnet mask, and supports multiple network layer protocols..

Encryption - Encoding data transmitted in a network..

Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium..

Firmware -The programming code that runs a networking device..

Flow Control - Enables lower speed devices to communicate with higher speed devices.. This is implemented by the higher speed device refraining from sending packets..

FTP (File Transfer Protocol) - A protocol used to transfer files over a TCP/IP network..

Full Duplex - The ability of a networking device to receive and transmit data simultaneously..

GARP (General Attributes Registration Protocol) - Registers client stations into a multicast domain..

Gateway - A device that interconnects networks with different, incompatible communications protocols..

GBIC (GigaBit Interface Converter) - A hardware module used to attach network devices to fiber-based transmission systems.. GBIC converts the serial electrical signals to serial optical signals and vice versa..

GVRP (GARP VLAN Registration Protocol) - Registers client stations into a VLANs..

Half Duplex - Data transmission that can occur in two directions over a single line, but only one direction at a time..

HTTP (HyperText Transport Protocol) - The communications protocol used to connect to servers on the World Wide Web..

HTTPS (HyperText Transport Protocol Secure) - An extension to the standard HTTP protocol that provides confidentiality by encrypting the traffic from the website.. By default this protocol uses TCP port 443..

ICMP (Internet Control Message Protocol) - Allows the gateway or destination host to communicate with the source host.. For example, to report a processing error..

IGMP (Internet Group Management Protocol) - Allows hosts to notify their local switch or router that they want to receive transmissions assigned to a specific multicast group..

IP (Internet Protocol) - A protocol used to send data over a network..

IP Address - The address used to identify a computer or device on a network..

IPCONFIG - A Windows 2000 and XP utility that displays the IP address for a particular networking device..

IPSec (Internet Protocol Security) - A VPN protocol used to implement secure exchange of packets at the IP layer..

ISP (Internet Service Provider) - A company that provides access to the Internet..

Jumbo Frames - Enable transporting identical data in fewer frames.. Jumbo Frames reduce overhead, lower processing time, and ensure fewer interrupts..

LAG (Link Aggregated Group) - Aggregates ports or VLANs into a single virtual port or VLAN..

LAN - The computers and networking products that make up your local network..

48-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet

SRW248G4P specifications

Cisco Systems SRW248G4P is a high-performance Layer 2 switch designed specifically for small to medium-sized businesses that require robust networking solutions. This switch supports Power over Ethernet (PoE), providing a highly flexible option for powering devices such as IP phones, wireless access points, and surveillance cameras.

One of the standout features of the SRW248G4P is its 48 10/100 Ethernet ports, which ensure ample connectivity for various networked devices. Additionally, it offers four Gigabit Ethernet uplink ports, allowing for seamless integration with existing network infrastructure and facilitating high-speed data transfer. The combination of these ports enables businesses to expand their network capabilities as needed without the immediate requirement for added devices.

The SRW248G4P comes equipped with advanced Layer 2 switching capabilities, including VLAN support, which enables the segmentation of network traffic for improved performance and security. It also supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), which help prevent network loops and ensure redundancy. With features like Link Aggregation Control Protocol (LACP), multiple physical connections can be combined into a single logical link, enhancing bandwidth and providing failover capabilities.

Another critical attribute of the Cisco SRW248G4P is its user-friendly management interface. The switch can be managed through a web-based interface, allowing IT administrators to configure settings, monitor performance, and troubleshoot issues with ease. Additionally, it supports SNMP (Simple Network Management Protocol) for integration with network management systems, further simplifying monitoring tasks.

Power over Ethernet functionality is a significant advantage of the SRW248G4P, providing up to 15.4 watts per port. This capability simplifies installation and reduces the clutter of power cords and outlets. Organizations can deploy PoE-enabled devices in locations that lack power sources, thus enhancing overall flexibility in network design.

In summary, the Cisco Systems SRW248G4P is a feature-rich switch tailored for small to medium-sized enterprises. Its blend of performance, management capabilities, and advanced features like PoE makes it a valuable asset in any organization's networking setup.
