Additional Details:

The RTL8363S-VC-GR typically supports features such as auto-negotiation for automatic speed and duplex setting. Its MAC address table enables efficient packet forwarding by learning and storing the MAC addresses of connected devices. The VLAN features enhance network security and segmentation, while QoS allows for prioritization of time-sensitive traffic, such as VoIP or video streaming. IGMP snooping is used to optimize multicast traffic, preventing unnecessary flooding of packets. The loop detection feature helps prevent network loops, which can cause broadcast storms and network outages. The integrated PHYs support 10BASE-T and 100BASE-TX Ethernet standards. Power consumption is minimized through EEE, which reduces power during periods of low network activity. It's often used in both managed and unmanaged switch applications.
