Using the HCCN Tool
During distributed training, you need to use the HCCN Tool in the Ascend software to configure the NIC IP address of the device. This IP address is used for communication between devices to synchronize network model parameters. If you need to use other functions of the HCCN tool (for example, checking the link status of a network port), see the Atlas Center Training Server 23.0.0 HCCN Tool Interface Reference or Atlas A2 Center Training Hardware 23.0.0 HCCN Tool Interface Reference.
