Question

 I upgraded the NX -OS on Nexus 7K and after upgrade. I could not longer console in. What could be the root cause?

Answer

 Check the line console config and the speed is not set to 9600  after upgrade per below

line Console:
Speed: 38400 baud
Databits: 8 bits per byte
Stopbits: 1 bit(s)
Parity: none
Modem In: Disable
Modem Init-String -
default : ATE0Q1&D2&C1S0=1\015
Statistics: tx:8095393 rx:687 Register Bits:fe:229

 

To resolve:

SW01# conf t
SW01(config)# line console
SW01(config-console)# speed 9600
SW01# copy run start
