creating a cifs share via cli is stated in https://www.dell.com/support/kbdoc/en-us/000043071

On the Data Domain system prompt type:

# cifs share create path {max-connections  |clients | browsing {enabled | disabled} |writeable {enabled | disabled} | users | comment }

Example:

# cifs share create backup path /backup
