Access Mode - Specifies the method by which user access is granted to the system..

Access Point - A device that allows wireless-equipped computers and other devices to communicate with a wired network.. Also used to expand the range of a wireless network..

Access Profiles - Allows network managers to define profiles and rules for accessing the device.. Access to management functions can be limited to user groups, which are defined by the following criteria:

•Ingress interfaces

•Source IP address and/or Source IP subnets..

ACE - Filters in Access Control Lists (ACL) that determine which network traffic is forwarded.. An ACE is based on the following criteria:

•Protocol

•Protocol ID

•Source Port

•Destination Port

•Wildcard Mask

•Source IP Address

•Destination IP Address

ACL (Access Control List) - Access Control Lists are used to grant, deny, or limit access devices, features, or applications..

Auto-negotiation- Allows 10/100 Mbps or 10/100/1000 Mbps Ethernet ports to automatically establish the optimal duplex mode, flow control, and speed..

Back Pressure - A mechanism used with Half Duplex mode that enables a port not to receive a message..

Bandwidth - The transmission capacity of a given device or network..

Bandwidth Assignments - Indicates the amount of bandwidth assigned to a specific application, user, and/or interface..

Glossary

Baud - Indicates the number of signaling elements transmitted each second..

Best Effort - Indicates that traffic is assigned to the lowest priority queue, and packet delivery is not guaranteed..

Bit - A binary digit..

Boot - To start a device and cause it to start executing instructions..

Browser - An application program that provides a way to look at and interact with all the information on the World Wide Web..

Bridge - A device that connect two networks.. Bridges are hardware specific, however they are protocol independent.. Bridges operate at Layer 1 and Layer 2 levels..

Broadcast Domain - Devices sets that receive broadcast frames originating from any device within a designated set.. Routers bind Broadcast domains, because routers do not forward broadcast frames..

Broadcast Storm - An excessive amount of broadcast messages simultaneously transmitted across a network by a single port.. Forwarded message responses are heaped onto the network, overloading network resources or causing the network to time out..

Burst - A packet transmission at faster than normal rates.. Bursts are limited in time and only occur under specific conditions..

Burst Size - Indicates the burst size transmitted at a faster than normal rate..

Byte - A unit of data that is usually eight bits long

Cable Modem - A device that connects a computer to the cable television network, which in turn connects to the Internet..

CBS (Committed Burst Size) - Indicates the maximum number of data bits transmitted within a specific time interval..

CIR (Committed Information Rate) - The data rate is averaged over a minimum time increment..

Class Maps - An aspect of Quality of Service system that is comprised of an IP ACL and/or a MAC ACL.. Class maps are configured to match packet criteria, and are matched to packets in a first-fit fashion..

Combo Ports - A single logical port with two physical connections, including an RJ-45 connection and a SFP connection..

Communities - Specifies a group of users which retain the same system access rights..

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. By ensuring reliable connectivity and ease of management, businesses can focus more on growth and their core objectives rather than worrying about network complexities.
