4.3.2 Verifying SMB Connection
To verify the SMB connection on the SMB client:
Step 1. Copy the large file to create a new session with the SMB Server.
Step 2. Open a PowerShell window while the copy is ongoing.
Step 3. Verify the SMB Direct is working properly and that the correct SMB dialect is used.
4.4 Verifying SMB Events that Confirm RDMA Connection
To confirm RDMA connection, verify the SMB events:
Step 1. Open a PowerShell window on the SMB client.
Step 2. Run the following cmdlets.
NOTE: Any RDMA-related connection errors will be displayed as well.
Get-SmbConnection
Get-SmbMultichannelConnection
netstat.exe -xan | ? {$_ -match "445"}
If you have no activity while you run the commands above, you might get an empty list
due to session expiration and no current connections.
Get-WinEvent -LogName Microsoft-Windows-SMBClient/Operational | ? Message -match "RDMA"
