3.1 네트워크 관리 기능

The keepLiNK switch offers advanced L2/L2+/L3 management capabilities:

• 서비스 품질(QoS): Prioritize network traffic to ensure critical applications (e.g., video conferencing, VoIP) receive sufficient bandwidth.
• IGMP 스누핑: 멀티캐스트 트래픽 전달을 최적화하여 모든 포트에 대한 불필요한 멀티캐스트 패킷 플러딩을 방지합니다.
• 링크 집계(LACP): 여러 개의 물리적 링크를 단일 논리적 링크로 결합하여 대역폭과 중복성을 높입니다.
• 흐름 제어: Manages data flow between devices to prevent packet loss during network congestion.
• 정적 라우팅: Allows for manual configuration of routing paths for specific network segments.

3.2 네트워크 보안

Implement robust security measures using the switch's built-in features:

• 802.1Q VLAN: Segment your network into virtual local area networks to enhance security and manage broadcast domains.
• IP-MAC-포트 바인딩: Binds specific IP and MAC addresses to individual ports, preventing unauthorized access.
• 접근 제어 목록(ACL): 다양한 기준에 따라 네트워크 트래픽을 필터링하는 규칙을 정의합니다.
• 항구 보안: MAC 주소 플러딩 공격을 방지하기 위해 포트에서 허용되는 MAC 주소 수를 제한합니다.
• DoS 방어: 네트워크를 서비스 거부 공격으로부터 보호합니다.
• 폭풍 통제: 브로드캐스트, 멀티캐스트 또는 알 수 없는 유니캐스트 스톰으로 인한 네트워크 성능 저하를 방지합니다.
• DHCP 스누핑: Filters untrusted DHCP messages and builds a DHCP snooping binding table.
• 802.1X Radius 인증: 포트 기반 네트워크 접근 제어를 제공합니다.

3.3 클라우드 관리

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.

4. 유지관리

To ensure optimal performance and longevity of your keepLiNK network switch, follow these maintenance guidelines:

5. 문제 해결

If you encounter issues with your keepLiNK switch, consider the following troubleshooting steps:

• 전원 없음:
  • 전원 케이블이 스위치와 전원 콘센트에 단단히 연결되어 있는지 확인하세요.
  • 전원 콘센트가 작동하는지 확인하세요.
• 링크/연결 없음:
  • Check the Ethernet cables for proper connection and damage.
  • 연결된 장치의 전원이 켜져 있고 올바르게 작동하는지 확인하세요.
  • SFP+ 포트의 경우 SFP+ 모듈이 올바르게 삽입되었고 호환되는지 확인하세요.
• PoE 장치가 켜지지 않음:
  • 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.
  • 해당 포트의 PoE 상태 LED를 확인하십시오.
• Web Interface Access Issues:
  • 컴퓨터의 IP 주소가 스위치와 동일한 서브넷에 있는지 확인하십시오.
  • Ensure you are using the correct IP address, username, and password.
  • 브라우저 캐시를 지우거나 다른 브라우저를 사용해 보세요.
• 성능 문제:
  • Check for network loops (Spanning Tree Protocol should prevent this, but verify).
  • Monitor port utilization and overall network traffic via the web 인터페이스.
  • Ensure cables are of appropriate length and quality for the desired speed (e.g., Cat5e/Cat6 for Gigabit).
