NimbostratusF5 APM - limiting access to the bandwidth for network Access
I am looking for a way of restricting access to the available bandwidth for our SSL VPN users. I see within the 'Network Access' configuration (Network Settings) there is an option to set 'Client Interface Speed' in bits per second. I have attempted to find more information on this without much luck. The only references I can find are below:
'Specifies the maximum speed of the client interface connection, in bits per second.' 'Specifies the speed of the client interface connection, in bits per second.'
Can anyone provide further insight to this particular setting? I want to confirm/understand: (1) if this is actually a bandwidth restriction or whether it is just an administrative setting (though the above suggests a restriction) (2) if it is a bandwidth restriction, does this perform Traffic Policing or shaping? (3) is the setting per client connection, or all connections using that particular 'network access'
Thanks

The "Client Interface Speed" feature was primarily designed for specific functionalities in older Windows versions:
That includes:- Helping the OS adjust the TCP receive window size.
- Displaying the interface speed in a taskbar tooltip pop-up when hovering over network adapters.
With the advent of Windows 10, there were significant changes in how the OS managed TCP-related features. Consequently, the "Client Interface Speed" setting became less influential.
If your goal is to adjust the bandwidth of the VPN connection, please see the Creating a client rate class section of Shaping Traffic on the Network Access Client article.

You can do bandwidth control using 'Client Traffic Control'

Ever find-out anymore information on this by chance?
NZ_David_20489Thanks for the information - however we are version 11.2 and not 11.5. We are planning to upgrade in the near future. I am still interested in information about the 'Client Interface Speed' which seems a quick and easy fix.
