error log

mount error(22): Invalid argument
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

solution
View root cause:

tail -f /var/log/kern.log

Note:

No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount.

The solution has been specified in the prompt, and the version of cifs shared is not specified, cifs is divided into smb1.0/2.0/3.0/3.1.
Solution

sudo mount -t cifs //ip/sharename /tmp/1 -o username=11,password=tmm,vers=1.0
