GS308T - Enable port rate limiting
Hi there, I was wondering if anybody could help me enable rate-limiting on a couple of ports on the switch. I'm not 100% sure how to do that. My configuration is such that these two ports have W...

9. In the Interface Shaping Rate field, specify the maximum outbound transmission rate
bandwidth in kbps.
This setting is used to shape the outbound transmission rate in increments of 16 kbps in
the range from 16 to 1,000,000 kbps. This value is controlled independently of any
per-queue maximum bandwidth configuration. It is effectively a second-level shaping
mechanism. The default value is 0. The value 0 means that the maximum is unlimited.
The expected shaping at egress interface is calculated as follows:
frameSize × shaping/(frameSize + IFG), where IFG (Inter frame gap) is 20 bytes,
frameSize is configured frame size, and shaping is configured traffic shaping.
For example, if 64 bytes frame size and 64 kbps shaping are configured, the expected
shaping is approximately 48 kbps.
10. In the Interface Ingress Rate Limit field, specify the maximum inbound transmission rate
bandwidth in kbps.

This setting is used to shape the inbound transmission rate in increments of 16 kbps in
the range from 16 to 1,000,000 kbps. The interface discards traffic that arrives at a
bandwidth in excess of the specified limit.

Pefect! Thanks for that. I had actually done just that, but wanted the confirmation that it was the right method to use to get where and what I wanted.
I configured the 2 ports, and then tested with my desktop PC using speedtest.net. Both checked out as being properly configured speed-limit-wise, as per those instructions.
Thanks again!
