Symptom
+ Configuration modification example below:
N9504(config)# interface Ethernet1/3
N9504(config-if)# mtu 9216
N9504(config-if)# ip flow monitor NETFLOW4-IN input >>>> The N9504 switch hangs at this point. Hitting Crtl+C returns error: Failed to collect returned stimulus
+ After this error, "copy run start" does not save configuration and aborts.
+ However, data can be saved to the bootflash and other local file systems.
Conditions
+ Issue may occur when modify NetFlow configurations.
Workaround
+ Save current running config to bootflash, other local file system or USB.
