3. Mode d'emploi
3.1 Fonctionnalités de gestion de réseau
The keepLiNK switch offers advanced L2/L2+/L3 management capabilities:
- Qualité de service (QoS) : Prioritize network traffic to ensure critical applications (e.g., video conferencing, VoIP) receive sufficient bandwidth.
- Surveillance IGMP : Optimise la distribution du trafic multicast, en évitant l'inondation inutile de tous les ports par des paquets multicast.
- Agrégation de liens (LACP) : Combine plusieurs liaisons physiques en une seule liaison logique pour une bande passante et une redondance accrues.
- Contrôle de flux : Manages data flow between devices to prevent packet loss during network congestion.
- Routage statique : Allows for manual configuration of routing paths for specific network segments.

3.2 Sécurité du réseau
Implement robust security measures using the switch's built-in features:
- VLAN 802.1Q : Segment your network into virtual local area networks to enhance security and manage broadcast domains.
- Liaison IP-MAC-Port : Binds specific IP and MAC addresses to individual ports, preventing unauthorized access.
- Access Control Lists (ACL): Définir des règles pour filtrer le trafic réseau en fonction de différents critères.
- Sécurité des ports : Limits the number of MAC addresses allowed on a port to prevent MAC flooding attacks.
- Défense contre les attaques DoS : Protège le réseau contre les attaques par déni de service.
- Contrôle des tempêtes : Empêche la dégradation des performances du réseau causée par les tempêtes de diffusion, de multidiffusion ou de monodiffusion inconnue.
- Surveillance DHCP : Filters untrusted DHCP messages and builds a DHCP snooping binding table.
- Authentification Radius 802.1X : Provides port-based network access control.

3.3 Gestion du Cloud
While the switch primarily uses WEB management, it supports cloud management through the MQTT protocol if you have an existing cloud platform. Consult your cloud platform's documentation for integration details.
3.4 PoE Operation (for PoE-enabled models)
This switch supports Power over Ethernet (PoE) on its RJ45 ports, allowing compatible devices to receive power and data over a single Ethernet cable. Ensure your connected devices are PoE-compatible.

5. Dépannage
If you encounter issues with your keepLiNK switch, consider the following troubleshooting steps:
- Pas d'alimentation :
- Assurez-vous que le câble d'alimentation est bien branché à la fois à l'interrupteur et à la prise de courant.
- Vérifiez que la prise de courant est fonctionnelle.
- Aucun lien/connectivité :
- Check the Ethernet cables for proper connection and damage.
- Vérifiez que l'appareil connecté est allumé et fonctionne correctement.
- Pour les ports SFP+, assurez-vous que le module SFP+ est correctement inséré et compatible.
- Le périphérique PoE ne s'allume pas :
- Confirm that the connected device is a standard PoE (802.3af/at) compliant device.
- If connecting a passive PoE camera, ensure a PoE splitter is used between the switch and the camera. Direct connection of passive PoE devices to an active PoE switch will not work. Refer to Video 2 for correct operation.
- Vérifiez le voyant d'état PoE du port concerné.
- Web Interface Access Issues:
- Verify your computer's IP address is in the same subnet as the switch.
- Ensure you are using the correct IP address, username, and password.
- Essayez de vider le cache de votre navigateur ou d'utiliser un autre navigateur.
- Problèmes de performance :
- Check for network loops (Spanning Tree Protocol should prevent this, but verify).
- Monitor port utilization and overall network traffic via the web interface.
- Ensure cables are of appropriate length and quality for the desired speed (e.g., Cat5e/Cat6 for Gigabit).
