Role of core switch MOAXA

Moxa core switches provide high-performance industrial networking with Layer 3 routing, redundancy protocols, advanced security, and support for industrial communication protocols.

High-Performance Switching

Moxa core switches, such as the ICS-G7826A series, feature 24 Gigabit Ethernet ports with up to 2 10 Gigabit Ethernet ports, while the 10GbE industrial core switches can include up to 4 10GbE ports . These switches support full Gigabit backbone capability, enabling rapid transfer of large volumes of video, voice, and data across industrial networks . Layer 3 switching functionality allows for routing between VLANs and networks, facilitating large-scale industrial deployments .

Redundancy and Reliability

To ensure network availability, Moxa core switches support Turbo Ring, Turbo Chain, and RSTP/STP redundancy protocols, providing fast recovery in case of link failures . They are designed with fanless operation and isolated redundant power supplies, enhancing reliability in harsh industrial environments .

Industrial Protocol Support

These switches are compatible with major industrial protocols, including EtherNet/IP, PROFINET, and Modbus TCP, allowing seamless integration with automation and control systems . They also support IGMP snooping and GMRP for efficient multicast traffic management, which is critical for SCADA and video applications .

VLAN and Network Management

Moxa core switches offer advanced VLAN capabilities, including Q-in-Q tagging, IEEE 802.1Q VLAN, and GVRP, simplifying network segmentation and planning . They support DHCP Option 82 for IP address assignment and port trunking to optimize bandwidth utilization .

Security and Access Control

Security features include TACACS+, SNMPv3, IEEE 802.1X, HTTPS, and SSH, along with access control lists (ACLs) to manage network access and enhance protection against unauthorized use . Quality of Service (QoS) is supported via IEEE 802.1p/1Q and TOS/DiffServ, ensuring deterministic traffic handling for critical industrial applications .

Management and Monitoring

Moxa core switches provide a command line interface (CLI) for configuration and support SNMPv1/v2c/v3 for network monitoring and management . Automatic warning by exception through email and relay output allows proactive network maintenance .

Applications

These switches are ideal for large-scale industrial networks, including power automation, transportation, manufacturing, and surveillance systems, where high reliability, fast data transfer, and industrial protocol support are essential .

In summary, Moxa core switches combine high-speed Layer 3 routing, industrial-grade reliability, redundancy, protocol support, and advanced security, making them suitable for critical industrial network backbones.
