4.3 Collegamento dei cavi di rete

• Porte RJ45: Connect standard Ethernet cables from your network devices (computers, servers, other switches) to the 8x GbE RJ45 ports.
• Porte SFP+: Insert compatible SFP+ transceivers into the 2x SFP+ ports, then connect fiber optic cables to the transceivers for high-speed uplinks or downlinks.
• Porta della console: For initial configuration or advanced troubleshooting, connect a serial cable from your computer to the CONSOLE port.

5. Configurazione iniziale

5.1 Accesso al Web Interfaccia utente (Web UI)

Il GWN7811 può essere gestito tramite un web-interfaccia utente grafica (GUI) basata su.

1. Connect a computer directly to any of the GWN7811's RJ45 ports.
2. Ensure your computer's IP address is in the same subnet as the switch's default IP address (e.g., 192.168.1.x). The default IP address for the GWN7811 is typically 192.168.1.1.
3. Aprire un web browser and enter the switch's default IP address (e.g., http://192.168.1.1) nella barra degli indirizzi.
4. Enter the default username and password (refer to the Quick Installation Guide or device label for default credentials).
5. Dopo aver effettuato l'accesso con successo, avrai accesso a Web UI for further configuration.

5.2 Basic Network Settings

After logging in, it is recommended to configure basic network settings:

• Cambia password predefinita: Per motivi di sicurezza, modificare immediatamente la password predefinita dell'amministratore.
• Configurazione dell'indirizzo IP: Configure a static IP address for the switch that is suitable for your network environment, or enable DHCP client if applicable.
• Ora di sistema: Set the correct system time and configure NTP (Network Time Protocol) for accurate time synchronization.

6. Istruzioni per l'uso

The GWN7811 is a Layer 3 managed switch, offering advanced features for network control and optimization.

6.1 Layer 3 Features

• Routing statico: Configurare percorsi statici per indirizzare il traffico tra diverse subnet IP.
• Inter-VLAN Routing: Enable routing between configured VLANs to allow communication across different broadcast domains.
• DHCP Server/Relay: The switch can act as a DHCP server for connected devices or relay DHCP requests to an external server.

6.2 Configurazione VLAN

Virtual Local Area Networks (VLANs) segment your network into logical broadcast domains, improving security and performance.

1. Navigate to the VLAN section in the Web UI.
2. Create new VLANs by assigning a VLAN ID and name.
3. Assign ports to specific VLANs as either access ports (for end devices) or trunk ports (for connecting to other switches).

6.3 Qualità del servizio (QoS)

QoS allows you to prioritize network traffic, ensuring critical applications receive sufficient bandwidth.

• Configure QoS policies based on port, VLAN, IP address, or DSCP values.
• Apply bandwidth control to limit or guarantee bandwidth for specific traffic types.
