Description
Product Overview of the Cisco 24 Ports Token Ring Switch
The Cisco WS-C3920 24 Ports Token Ring Switch Catalyst 3920 is a network switch manufactured by Cisco Systems. This device is designed to facilitate the transfer of data between multiple devices within a computer network. Specifically, the WS-C3920 model is equipped with 24 ports and supports the Token Ring network protocol.
Understanding Network Switches
Before delving into the specifics of the Cisco WS-C3920, it’s essential to understand the role of network switches in computer networking. A network switch is a hardware device that connects multiple devices, such as computers, printers, and servers, within a local area network (LAN). It operates at the data link layer of the OSI model and is responsible for forwarding data packets between devices. The Cisco WS-C3920 24-Port Token Ring Switch Catalyst 3920 is a networking device designed to support Token Ring technology. As part of Cisco’s Catalyst series of switches, it offers a range of features and capabilities tailored to the needs of Token Ring networks.
Token Ring Network Protocol
The Token Ring network protocol is a communication standard used in local area networks. Unlike Ethernet, which uses a contention-based access method, Token Ring utilizes a token-passing mechanism. In a Token Ring network, devices are arranged in a logical ring topology, and a token circulates the network. Only the device holding the token can transmit data, ensuring orderly communication and minimizing collisions.
Features of Cisco WS-C3920
24 Ports
The switch is equipped with 24 ports, enabling simultaneous connections for multiple devices. This high port density is well-suited for medium to large-scale network deployments.
Token Ring Support
As indicated by its name, the WS-C3920 supports the Token Ring network protocol. It is compatible with Token Ring devices and can seamlessly integrate into existing Token Ring networks.
Layer 2 Switching
Operating at the data link layer (Layer 2) of the OSI model, the switch can forward data packets based on MAC addresses. This facilitates efficient communication between devices within the same LAN segment.
Redundancy and Resilience
Cisco switches are known for their robustness and reliability. The WS-C3920 incorporates features such as redundant power supplies and hot-swappable modules to minimize downtime and ensure uninterrupted network operation.
Quality of Service (QoS)
