Setting switchport rate limit on M4100

Hi, 

 

I am presently trying to come up with a solution to control bandwidth across a site with multiple clients, using Netgear switches.

 

One of the switches deployed is a GS728TP and I can easily set limits under the COS settings for the ingress and egress on each port. This works great!

 

The other three switches we have are M4100 and I have looked at traffic-shaping through the Web interface. I understand from documentation that any limits are set as a percentage and therefore would be different for a client connected at 100Mbps Vs 1Gbps. I also see that there is a 5% granularity, which on a Gb link is not really small enough for us. (Also this only throttled download when tested (not upload))

 

I then found a link on this site referring to M4300 switches and ACL rules, so I attempted to configure this, and all was looking good. However it would not apply the out rule on the port. (Only the in option was available). 

 

Is there a way to achieve the kind of rate-limiting we have applied on the GS728TP with the M4300? Using either the web interface or CLI for ACL rules or similar?

Many thanks for reading!
