Software Function<\/strong><\/em><\/h2>\n
\n
\n
Long Range:<\/div>\n
Ports 1 to 48: up to 300 m. Long range performance may vary depend on camera model or cable condition.<\/div>\n<\/div>\n
\n
Port Isolation:<\/div>\n
Ports 1 to 52: 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.<\/div>\n<\/div>\n
\n
PoE Watchdog:<\/div>\n
Ports 1 to 48: auto detect and restart the cameras that do not respond.<\/div>\n<\/div>\n
\n
Link Aggregation:<\/div>\n
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.<\/div>\n<\/div>\n
\n
QoS :<\/div>\n
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.<\/div>\n<\/div>\n
\n
Loop Prevention:<\/div>\n
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. Support 802.1w RSTP. Support G.8032 ERPS.<\/div>\n<\/div>\n
\n
VLAN:<\/div>\n
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.<\/div>\n<\/div>\n
\n
HPP:<\/div>\n
Support one-click activation and remote management via Hik-Partner Pro. Functions supported: 1. Display the port rate. 2. Display the port bandwidth utilization rate. 3. Display the PoE power usage. 4. Display topology information. 5. Display the alarm status. 6. Restart ports and devices. 7. Enable port long-rage mode. 8. Remotely upgrade the device.<\/div>\n<\/div>\n
\n
System Maintenance:<\/div>\n
Support device management via web. Support DHCP Client. Enabled by default for dynamic assignment of management IP addresses. Support Super IP, which is a fixed IP address (10.180.190.200) for direct access. Support management via Hik-Central Pro. Support remote management via Hik-Partner Pro. Support cable detection. Abnormal open circuits and short circuits as well as network cable length can be detected. Supports 802.1ab LLDP for peer device discovery. Support port mirroring for fault locating.<\/div>\n<\/div>\n
\n
Port Rate-Limiting:<\/div>\n
Port rate-limiting is used for port bandwidth adjustment to prevent network congestion.<\/div>\n<\/div>\n
\n
Storm Control:<\/div>\n
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.<\/div>\n<\/div>\n
\n
DHCP Snooping:<\/div>\n
DHCP Snooping can prevent unauthorized connections to DHCP servers from disrupting the network and affecting normal network communication, and only allow DHCP packets from trusted ports to pass through. Disable by default.<\/div>\n<\/div>\n
\n
ACL:<\/div>\n
Port security strategy. Support up to 64 ACL entries. Support up to 128 configuration rules under all ACL entries.<\/div>\n<\/div>\n
\n
IPSG:<\/div>\n
IPSG can control the security of port access device. Support port, MAC, IP binding. Support 256 security entries.<\/div>\n
