Configuration Example
■
The GigabitEthernet1/0/1 of the switch is accessed into the 10.1.1.1/24 network
segment
■
Perform TP on the packets from the 10.1.1.1/24 network segment and the rate of
TP is set to100kbps
■
The packets within the specified traffic are forwarded after their DSCP precedence
is marked as 16, and the packets beyond the traffic are forwarded after their DSCP
precedence is marked as 56

The statistics of TP includes the bytes of
the packets within the limited rate and
the bytes of the packets beyond the
limited rate.
When the statistics count reaches the
upper threshold, the switch will restart
statistics. It is recommended to use the
