The role of an Ethernet switch is to forward Ethernet frames from one port to another. The presence of a FIB is one attribute that separates a switch from a hub. Without a functional FIB, all frames received by a network switch would be echoed back out to all other ports, much like an Ethernet hub.
A LAG is a method of inverse multiplexing over multiple Ethernet links, thereby increasing bandwidth and providing redundancy. It is defined by the IEEE 802.1AX-2008 standard, which states, "Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation Group, such that a MAC client can treat the Link Aggregation Group as if it were a single link."

RDMA over Converged Ethernet (RoCE) [1] is a network protocol which allows remote direct memory access (RDMA) over an Ethernet network. There are multiple RoCE versions. RoCE v1 is an Ethernet link layer protocol and hence allows communication between any two hosts in the same Ethernet broadcast domain.
An overwhelmed network node can send a pause frame, which halts the transmission of the sender for a specified period of time. A media access control (MAC) frame (EtherType 0x8808) is used to carry the pause command, with the Control opcode set to 0x0001 (hexadecimal). [1] Only stations configured for full-duplex operation may send pause frames.
That way, a common Ethernet connection becomes shared between the computer's operating system and the integrated baseboard management controller (BMC), usually by configuring the network interface controller (NIC) to perform Remote Management Control Protocol (RMCP) ports filtering, use a separate MAC address, or to use a virtual LAN . Thus ...

The number of switch port states a port can be in has been reduced to three instead of STP's original five: Discarding – No user data is sent over the port; Learning – The port is not forwarding frames yet, but is populating its MAC address table; Forwarding – The port is fully operational; RSTP operational details:
