Configure rate limiting.
Sample configuration. 

'set port ratelimit' 

As described in the Matrix DFE Configuration Guide, the ratelimit command has the format:

set port ratelimit {disable | enable} | <port-string> <priority>
<threshold> {disable | enable} [inbound | outbound] [<index>]

The 'threshold' is stated in kilobytes per second, within the range of 125 through the maximum rate for the port. 

Here is an example of a one-port rate limit of 30 Megabits per second (30 million bits per second divided by 8 thousand bits per second = 3750), applied bi-directionally to all traffic priorities:

DFE(rw)->set port ratelimit enable
DFE(rw)->set port ratelimit fe.1.1 0-7 3750 enable

Note that Inbound and Outbound rate limiting is more typically applied using the cos/policy commands, by means of NetSight Policy Manager.
