Abstract: This application discloses a bit error indication method for a service stream and a communication apparatus, so that when a quantity of bit errors that is counted inside a device exceeds a preset threshold, it can be ensured that the device continues to work normally. The method includes: A network device receives a first signal stream from a first node by using N slots of a first bonding group, determines a first check value based on a first check code in the first signal stream, determines a second check value based on the first check value and a current check value, and sends a second signal stream to a second node by using M slots of the first bonding group. The second signal stream includes a target check value determined based on the second check value.

Abstract: This application provides an isolation and recovery method and related network device for a case when one or more physical layer apparatuses (PHYs) in a flexible Ethernet group (FlexE group) are faulty. In the method, if a network device determines that a first overhead block corresponding to each current available PHY is stored in a corresponding memory, the network device determines that a FlexE group meets a PHY alignment condition, and starts to simultaneously read cached data from all memories. Therefore, there is no need to insert local fault LF code blocks to all clients, and there is no need to recreate a group. This effectively reduces the impact of a faulty PHY on client services carried by a normal PHY.
