Software Function

• Long Range
  • Ports 1 to 48: up to 300 m.
  • Long range performance may vary depend on camera model or cable condition.
• Port Isolation
  • Ports 1 to 48: port isolation mode to improve network security.
  • Ports in an isolation group cannot communicate with each other, but they can communicate with ports outside the isolation group.
• PoE Watchdog : Ports 1 to 48: auto detect and restart the cameras that do not respond.
• Link Aggregation
  • Link aggregation is used to aggregate multiple physical ports to form a logical port for load balancing, bandwidth expansion, and port protection.
  • Support static link aggregation.
  • Support 8 aggregation groups.
• QoS
  • QoS is used to allocate bandwidth to different services so as to provide end-to-end service quality assurance.
  • Support port-based priority configuration.
  • Support SP, WRR priority schedule mode.
• Loop Prevention
  • Loop prevention is used to prevent the switching network from forming loops, which will seriously affect network communication. Disabled by default.
  • Support 802.1D STP.
  • Suppport 802.1w RSTP.
• VLAN
  • VLAN is used for network scale planning and network health improvement.
  • Support 802.1Q.
  • Configurable VLAN ID from 1-4094.
  • Support Trunk, Access port mode.
  • Support Max. 4094 VLAN.
• HPP
  • Support one-click activation and remote management via Hik-Partner Pro. Functions supported:
    • Display the port rate.
    • Display the port bandwidth utilization rate.
    • Display topology information.
    • Display the alarm status.
    • Restart ports and devices.
    • Remotely upgrade the device.
• System Maintenance : Support remote upgrade, default parameter restoration, logs viewing, basic network parameter configuration, import and export configuration, and time synchronization.
• Port Rate-Limiting : Port rate-limiting is used for port bandwidth adjustment to prevent network congestion.
• Storm Control
  • Storm control is used to prevent switch ports from being blocked by broadcast or multicast storms in the LAN, which may affect network communication.
  • Support port rate limiting based on broadcast, multicast, and unknown unicast packets.
