Configuration Mode Commands : SteelHead Configuration Commands : CIFS, SMB, SMB2, and SMB3 Support Commands : protocol cifs smbv1-mode enable
  
protocol cifs smbv1-mode enable
Enables SMBv1 backward compatibility mode, which allows a SteelHead to perform CIFS latency optimization and SDR on SMB traffic in Windows Vista environments.
Syntax
[no] protocol cifs smbv1-mode enable
Parameters
None
Usage
Improves SMB optimization for Windows Vista users. Use this command to perform latency and SDR optimizations on SMB traffic on the client-side SteelHead appliance. Without this feature, SteelHead appliances perform only SDR optimization without improving CIFS latency. This feature enables SMBv1 for Vista-to-Vista CIFS connections instead of SMBv2 (similar to Vista to pre-Vista CIFS connections). While the SteelHeads are fully compatible with the SMBv2 included in Vista, they deliver the best performance using SMBv1.
Important: You must restart the client SteelHead service after enabling the SMBv1 Backward Compatibility Mode.
To enable SDR and CIFS latency optimization on SMB traffic in a Windows Vista environment, perform the following steps on the client-side SteelHead:
1. Run the following command:
# protocol cifs smbv1-mode enable
2. Restart the SteelHead service.
# restart
The no command option disables this feature.
Example
amnesiac (config) # protocol cifs smbv1-mode enable
amnesiac (config) # service restart
