Acceleration Diagnostics

Where to view the acceleration diagnostics

Go to Configuration > System > Diagnostics > Acceleration. Select SMB Acceleration from the drop-down.

To view TCP acceleration configuration, number of accelerated connections, and reduction statistics

From the Module drop-down, select TCP Acceleration.

The configuration settings for TCP acceleration are displayed.

To view the SMB configuration

From the Module drop-down, select SMB Acceleration.
The configuration settings for SMB1 and SMB2 are displayed. The connections statistics are grouped into two categories:
- Concurrent — All signed connections from the file sharing servers that are currently connected.
- Total Signed — All signed connections since the SMB Acceleration service was last started, including those recorded as Concurrent.
As signed connections are processed, there are three possible results:
- Bypassed — The number of connections that bypass acceleration because the first time an attempt to validate the domain credentials failed, which resulted in the connection being identified as signed, but is not accelerated. All subsequent attempts to validate credentials of a signed connection against the IP address of the server are marked as Unhandled.
- Handled — The number of connections that are known to be signed and accelerated.
- Unhandled — The number of connections that, following a bypass state, had subsequent attempts to validate credentials of a signed connection against the IP address of the server.

To view the WAN memory configuration and reduction statistics for individual hosts

From the Module drop-down, select SMB Acceleration.

The configuration settings for WAN memory acceleration are displayed.
