Using LANVIEW

DFE modules use a built‐in visual diagnostic and status monitoring system called LANVIEW. The LANVIEW LEDs (Figure 4‐1) allow quick observation of the network status to aid in diagnosing network problems.

About the Management (MGMT) LED

The MGMT LED (shown in Figure 4‐1) indicates when the module is serving as the Management Module to control the management functions for all DFE modules in the chassis. The Management Module handles all IP requests to the chassis IP address, such as, but not limited to, PING, Telnet, SNMP, HTTP. The Management Module also handles the CLI configuration sessions through the console port. So, when you plug into a DFE module COM port to configure a DFE module in the chassis, it is handled by the Management Module regardless of the DFE module COM port that you use.

4G4205-72, 4G4285-49 specifications

Enterasys Networks is a distinguished name in the realm of networking solutions, offering a variety of high-performance switches and routers designed for enterprise environments. Among their impressive lineup, the 4G4285-49 and 4G4205-72 models stand out for their advanced capabilities and robust features that cater to the demanding needs of modern IT infrastructure.

The Enterasys 4G4285-49 is a high-density Layer 3 switch that provides exceptional performance and reliability. It is equipped to handle the increasing data traffic common in enterprise networks, facilitating enhanced throughput and reduced latency. This model features 48 Gigabit Ethernet ports, ideal for connecting a vast array of devices within a network, along with one or two 10 Gigabit SFP+ uplink ports, ensuring fast data transmission to other network segments.

On the other hand, the 4G4205-72 is specifically designed as a versatile access switch with 24 Gigabit Ethernet ports and an additional 4 SFP+ uplink ports. This configuration makes it perfect for connecting endpoints like computers, printers, and other network devices while also providing scalability for future expansion.

Both models leverage advanced technologies such as Virtual LAN (VLAN) support, which helps in segmenting network traffic for better performance and security. Quality of Service (QoS) features are integrated, allowing administrators to prioritize critical applications and ensure optimal performance during high traffic periods. Additionally, security protocols like Access Control Lists (ACLs) and port security measures safeguard the network against unauthorized access.

The Enterasys 4G4285-49 and 4G4205-72 also support advanced management capabilities. With intuitive web-based interfaces and support for SNMP (Simple Network Management Protocol), IT teams can efficiently monitor network performance and troubleshoot issues as they arise.

In terms of build quality, both models are designed for reliability, featuring robust chassis and components that withstand the rigors of a data center environment. Their energy-efficient designs also contribute to reduced operational costs, aligning with the growing demand for sustainable networking solutions.

In summary, Enterasys Networks' 4G4285-49 and 4G4205-72 models combine high performance, advanced networking technologies, and robust security features, making them ideal choices for enterprises looking to enhance their network infrastructure and manage increasing data demands effectively.
