Bandwidth Limitation (QoS) M4300-48XF

Hello,

we want to limit the bandwidth of several ports of the M4300-48XF, independent of the content.

The physical speed is 10GE, but we want to limit with 5GE for example.

I'm not a super expert and I don't have experience with Core-Switches.

I've read "Chapter 8 Configure Quality of Service" but I don't understand it completely.

Can somebody help please.

Thx.
