Supports half-duplex flow control and full-duplex back pressure mode, with each switch port supporting adaptive functionality. Provides a wired connection speed of up to 100M for your workgroup or server, making it convenient for plug-and-play use. Delivers a data transmission network with stable performance, high throughput, and wired connection speeds for every end-user connected to the LAN. Each port utilizes store-and-forward mode, effectively isolating broadcast storms, preventing network congestion, and avoiding network conflicts. Supports IPv4 IGMP v1/v2/v3 and IPv6 MLDv1/v2 snooping on all ports, along with IEEE 802.3x half-duplex flow control and full-duplex back pressure mode.
