Way to throttle Windows file copy operations?

We have four locations all connected via an Extreme router at each core (MPLS network between them with AdTran routers at each location).  We do have QoS configured on the MPLS, but we are still running into issue with Windows users copying a file from A to B and maxing out the connection.  What we were hoping to do either at the port level or Extreme Control (if it can do it) is somehow throttle Windows based file copies leaving  a location so that it doesn’t end up maxing out the bandwidth at our main site.  We debated upgrading the MPLS speed, but then we’ll just end up in the same boat (with users maxing that out), so it sounds like we really need to figure out a way to rate-limit/throttle the copies.

Hi Stephen,

 

This should be able to be done via meter configuration. Please see https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-configure-basic-rate-limiting-on-a-port-for-ingress-and-egress

We should match on the protocol tcp or udp and the appropriate port number for SMB.

 

Thanks
Brad

Hello Stephen, could you tell us which platform you’re using for Extreme?

Userlevel 2

x460G2 switches as the core at two locations with x440G2 switches connected to those (desktops are connected to the x440G2 units).  The co-location facilities are using x460-48t.

 

G2 switches are running EXOS EXOS 22.7.2.4 and the Gen1 switches are running EXOS 16.2.5.4-patch1-22

That might work.  We were really hoping for some solution that would trigger after a certain amount of time (i.e an extended large file copy).

Hi Stephen,

I’m not aware of any current way to do that, as the switch does not keep track of individual sessions. It would just strictly limit the sending of that traffic at a defined rate.

Thanks
Brad
