Remote Management and Monitoring
The WS-X4418-GB Cisco Catalyst 4500 18 Ports Server Switching offers several remote management and monitoring options to help administrators manage and maintain the switch from a remote location.
Cisco IOS Software: The switch runs on Cisco IOS Software, which provides a wide range of management and monitoring options such as command-line interface (CLI) and Simple Network Management Protocol (SNMP). The CLI allows administrators to manage and configure the switch using a terminal emulation program, while SNMP allows for monitoring and management of the switch using network management systems (NMS) such as CiscoWorks.
Cisco Network Assistant: Cisco Network Assistant is a web-based management tool that simplifies the configuration and management of Cisco switches, routers, and wireless access points. It provides a centralized management interface that allows administrators to easily configure, monitor, and troubleshoot devices on the network.
Cisco Prime LAN Management Solution: Cisco Prime LAN Management Solution (LMS) is a comprehensive network management solution that provides automated device discovery, network monitoring, and troubleshooting. It allows administrators to view real-time network statistics, configure devices, and perform software upgrades from a single centralized console.
Cisco Smart Call Home: Cisco Smart Call Home is a feature that allows the switch to automatically send alerts and diagnostic information to Cisco for troubleshooting and analysis. This allows Cisco to proactively identify and resolve issues before they become critical, helping to reduce downtime and improve network availability.
Features and Benefits
The WS-X4418-GB is a module for the Cisco Catalyst 4500 series of switches, providing 18 Gigabit Ethernet ports for server switching. The following are the key features and benefits of this module:
- High-density ports: With 18 Gigabit Ethernet ports, the WS-X4418-GB provides a high-density solution for server connectivity, allowing administrators to connect more servers with fewer switches.
- Fast Ethernet and Gigabit Ethernet support: The module supports both Fast Ethernet and Gigabit Ethernet speeds, providing versatility and allowing administrators to choose the right speed for each server.
- Quality of Service (QoS): The WS-X4418-GB supports QoS, allowing administrators to prioritize network traffic based on specific needs, such as voice and video.
- Spanning Tree Protocol (STP): The module supports STP, which helps prevent network loops by creating a loop-free topology in the network.
- Hot-swappable: The module is hot-swappable, meaning it can be removed and replaced without affecting the rest of the network.
- Scalability: The WS-X4418-GB is part of the Cisco Catalyst 4500 series, a highly scalable and modular switching platform, allowing administrators to easily add additional modules and expand the network as needed.
Quality of Service (QoS) Capabilities
The WS-X4418-GB Cisco Catalyst 4500 18 Ports Server Switching offers advanced Quality of Service (QoS) capabilities to help ensure that mission-critical applications receive the necessary bandwidth and low latency.
Classification and Marking: The switch supports a variety of classification and marking methods, such as Layer 2 and Layer 3 marking, Access Control Lists (ACLs), and Differentiated Services Code Point (DSCP) marking. This allows administrators to classify and mark traffic based on various criteria such as IP address, protocol, and port number, ensuring that the right traffic gets the right priority.
Traffic Shaping and Policing: The switch supports both traffic shaping and policing to help control and manage network congestion. Traffic shaping allows administrators to limit the amount of traffic that enters the network, while policing drops excessive traffic that exceeds a set limit.
Congestion Management: The switch supports various congestion management techniques such as Weighted Random Early Detection (WRED) and Class-Based WRED (CB-WRED) to help prevent network congestion. WRED and CB-WRED allow the switch to selectively drop packets before a queue becomes full, helping to prevent network congestion and ensure that critical traffic is not dropped.
Prioritization: The switch supports multiple levels of priority queuing, including Low Latency Queuing (LLQ) and Class-Based Weighted Fair Queuing (CBWFQ), to help ensure that mission-critical applications receive the necessary bandwidth and low latency. LLQ allows administrators to assign a specific amount of bandwidth to a particular traffic class, while CBWFQ helps to ensure that all traffic classes receive a fair share of the available bandwidth.

About Refurbished Products
Different Types of Switches
Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).
The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.
The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.
The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.
Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.
Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.
Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
