1. Features
◆Meet the requirements of EN50155 layer 2 network management industrial Ethernet switch;
◆ Supports IEEE802.3, IEEE 802.3U, IEEE 802.3ab, IEEE 802.3AF, IEEE 802.3at, IEEE802.3x, IEEE 802.1p, IEEE 802.1Q, IEEE802.1d, IEEE802.1w;
◆ The switch module has 12 network ports, all interfaces are exported from the front panel, including seven 10/100Mbps (support POE power supply) M12-A and five 10/100/1000Mbps electrical ports M12-D;
◆ With 1 debug interface;
◆ G1 and G3 are a group of Bypass , G2 and G4 are a group of Bypass, which function is to prevent communication interruption caused by power supply fault;
◆ SNMPv1/v2c/v3 for different levels of network management;
◆ RMON can be used for efficient and flexible network monitoring;
◆ Port mirror can analyze and monitor data, convenient for online debugging;
QoS allows real-time traffic classification and prioritization.
◆ LLDP can realize automatic topology discovery, easy to visual management;
◆ DHCP server and DHCP client can be used to allocate IP address of different policies;
◆ File management to facilitate the rapid configuration of equipment and online upgrade;
◆ Log management records boot, operation, connection, threshold alarm of CRC check error frame, line detection of Ethernet interface etInformation, important events can be reported to the PIS controller through trap (whether this function is enabled and the address of the PIS controller can be set);
◆It supports the summary statistics of receiving and sending interface packets and port rate statistics.
◆ARP can be used for MAC address resolution;
◆ User password can manage users hierarchically, improve the security of equipment management;
◆ Anti-attack control, ACL and 802.1X authentication can enhance the flexibility and security of the network;
◆ Storm suppression can suppress broadcast, unknown multicast and unknown unicast;
◆ SSHD configuration can realize encrypted transmission data, prevent DNS and IP spoofing;
◆TELNET configuration and HTTPS configuration can ensure data access security;
◆ VLAN can simplify network planning by setting up virtual local area network, support access, trunk and hybird three modes;
◆Port aggregation can increase network bandwidth and enhance the reliability of network connection. Whether aggregation is enabled or not can be configured, and aggregation port failure has automatic protection mechanism, load balancing mode can be configured.
◆ Bandwidth management can allocate network bandwidth reasonably to prevent unpredictable network status;
◆ Port isolation can realize the port isolation between the same VLAN, which can save Vlan resources.
IGMP listening and querying and static multicast can be used to filter multicast traffic to save network bandwidth, and have a dynamic multicast group member protection mechanism;
◆ Network diagnosis and trouble shooting can be carried out through Ping, Traceroute and port loopback.
◆ Support loop detection function, master node support dynamic election, prevent misoperation caused by network loop and further lead to network storm;
◆ Support layer 3 speed forwarding, NAT switching bandwidth 30M;
◆ Support rstp, MSTP etc. standard ring protocol;
◆ The power outage does not affect the use of the switch during the upgrade of the dual version range
