Physical Port

• Four 10/100/1000BASE-T RJ45 ports with auto MDI / MDI-X function
• Two SFP interfaces, supporting 100/1000/2500BASE-X transceiver type auto detection 

Fiber Port Redundancy

• Automatically detects link status and redundancy on dual ports with the same connector type.
• Only primary port is active at a time, while the backup port is blocked.
• When primary port link failure occurs, the traffic will swap to backup port automatically.
• Once the primary-port status is back to link up, the traffic will swap from backup port to primary port. 

Layer 2 Features

• Supports auto-negotiation and 10/100Mbps half / full duplex and 1000Mbps full duplex mode
• High performance Store and Forward architecture, runt/CRC filtering eliminates erroneous packets to optimize the network bandwidth
• IEEE 802.3x flow control for full duplex operation and back pressure for half duplex operation
• 9K Jumbo Frame size support
• Backplane (Switching Fabric): 18Gbps
• Integrated address look-up engine, supporting 4K absolute MAC addresses
• Automatic address learning and address aging
• IEEE 802.1Q VLAN transparency
• CSMA/CD Protocol
