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.
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
