Because of this, cut-through switching cannot pass packets to higher speed networks, for example, to forward packets from a 10Mbps to a 100Mbps Ethernet network. Since the switch has forwarded most of the packet when the CRC is read, the switch cannot discard packets with CRC errors. However, the CRC check is still made and, if errors are found, the error count is updated. Cut-through switching is recommended for networks intended to provide one switch port per user, or for lightly loaded networks. It is essential for multimedia applications and ideal for workgroup environments where minimum delays are required.
Runts are typically the result of collision fragments.
Because of this, fragment-free switching cannot pass packets to higher speed networks, for example, to forward packets from a 10Mbps to a 100Mbps Ethernet network. Therefore, if you opt for fragment-free switching, you cannot make direct connections to higher speed networks from that port. Adaptive switching Adaptive switching mode is a user-defined facility to maximize the efficiency of the switch. As the numbers of runts and CRC errors change, so does the forwarding mode. Latency Latency is the delay measured from the time the packet first enters a network device until it leaves it.
