4. Istruzioni per l'uso (Web Gestione)
IL web-managed interface provides comprehensive control over the switch's features. After logging in, you can monitor device/port status and configure various network settings.
4.1 Basic Management Features
Figura 4.1.1: Oltreview of Basic Management Features. This image illustrates the range of configurable features accessible via the web interface, designed to optimize network efficiency.
The switch offers a suite of management features to optimize network performance and security. These include:
- VLAN (rete locale virtuale): Segmenta la tua rete per migliorare sicurezza e prestazioni.
- QoS (Qualità del servizio): Dare priorità al traffico di rete per le applicazioni critiche.
- Link Aggregation (LACP/Static): Combina più collegamenti fisici in un unico collegamento logico per aumentare la larghezza di banda e la ridondanza.
- Spanning Tree Protocol (STP/RSTP/MSTP): Prevenire i loop di rete.
- Multicast (IGMP Snooping): Optimize multimedia traffic delivery.
- Cornice gigante: Support for larger Ethernet frames to improve throughput.
- MAC Address Table Management: View and manage MAC addresses.
4.2 Configurazione VLAN
Figure 4.2.1: VLAN for Higher Security. This image demonstrates how VLANs (VLAN1, VLAN2) can be used to logically separate network traffic, enhancing security and management within a business network.
VLANs allow you to logically group devices on your network, regardless of their physical location. This enhances security by isolating traffic and improves network efficiency. The switch supports up to 31 static VLAN groups and configurable VLAN IDs from 1-4094. Refer to the web management interface's VLAN section for detailed configuration steps.
4.3 QoS (Quality of Service)
Figure 4.3.1: QoS for Fluent Online Experience. This image illustrates how administrators can prioritize different types of network traffic, such as voice and video, to ensure smooth and lag-free performance.
QoS features enable you to prioritize certain types of network traffic, such as voice or video, to ensure smooth and uninterrupted performance. This is crucial for applications sensitive to latency and packet loss. The switch supports SP and WRR scheduling and up to 8 queues per port. Configure QoS settings through the web interface to optimize your network for specific applications.
4.4 IGMP Snooping for Multicast Optimization
Figure 4.4.1: IGMP Snooping for Multicast Optimization. This image visually represents how IGMP Snooping enhances the delivery of multimedia traffic, leading to a better network experience, particularly for services like IPTV.
IGMP Snooping is a feature that optimizes the delivery of multicast traffic, such as IPTV or video conferencing streams. By intelligently forwarding multicast packets only to the ports that have requested them, it prevents unnecessary flooding of traffic across the network, conserving bandwidth and improving overall performance.
