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
