We have some problems with configuring Huawei AR1220 routers by executing command script. After executing each command in script NCM waits for about 10-20 seconds and then continues to another command in script. Since we have nearly 600 Huawei AR1220 routers it takes long time to configure them all. There are no such problems with Cisco routers. I guess NCM doesn't receive something from Huawei router and continues after some timeout.
