3Com Switch 7750 Configuration Guide

Configuring Rate Limit on Ports 671
Configuration Example Ethernet 2/0/1 of the switch is accessed into the 10.1.1.1/24 network segment
Remark the DSCP precedence of the traffic from the 10.1.1.1/24 network
segment to 56
Configuration procedure:
<SW7750> system-view
