Abstract
Technologies are provided for preventing transmission of cyclic redundancy check (CRC) errors, and/or other errors, within a computer network that uses cut-through forwarding of network packets. For example, counts of CRC errors can be maintained for network packets processed by network devices. When a CRC error condition is detected based on the counts of CRC errors, cut-through forwarding is disabled on at least a portion of the network (e.g., on one or more specific network ports and/or on one or more specific network devices). While cut-through forwarding is disabled, the affected portion of the network uses store-and-forward for processing network packets. When the CRC error condition no longer exists, then cut-through forwarding is re-enabled on the portion of the network.
