Description (partial)

The UUID is 16-byte number, represented in its canonical form as 32 hexadecimal digits, displayed in 5 groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters (32 digits and 4 hyphens).

N1k treats UUID as case sensitive string, thus the followings are treated as three different UUIDs, instead of one unique UUID:
vem 13
  host vmware id 45D870E1-6B28-11DE-BABA-000BAB01BFD6
vem 14
  host vmware id 45d870e1-6b28-11de-baba-000bab01bfd6
vem 15
  host vmware id 45d870e1-6b28-11de-baba-000BaB01bfd6

The all upper case, all lower case, or mix case UUID should be treated the same if the hexadecimal number is the same; VEM should be able to connect with the configured module number regardless the case of UUID configured; i.e., the above configuration if configured in sequence, only vem 13 config should be accepted.

Configuring host vmware UUID in upper or mix case.
