3Com Switch 7750 Configuration Guide

672 CHAPTER 61: QOS CONFIGURATION
n
Only non-type-A I/O Modules support port-based rate limit.
Configuration Example
■ Set rate limit on GigabitEthernet 2/0/1 of the switch
■ Limit the rate to 10 Mbps.
Configuration procedure:
<SW7750> system-view
[SW7750] interface GigabitEthernet 2/0/1
[SW7750-GigabitEthernet2/0/1] qos
[SW7750-qosb-GigabitEthernet2/0/1] line-rate 10
Configuring TP Refer to “TP” on page 661 for the introduction to TP.
Configuration
Prerequisites
■ ACL rules used for traffic identifying are defined. Refer to “Choosing ACL
Mode for Traffic Flows” on page 639 for defining ACL rules
■ The limit rate for TP, the actions for the packets within the specified traffic and
the actions for the packets beyond the specified traffic have been specified.
■ The ports that needs this configuration is specified
Configuration Procedure
of TP
acl-rule: Applied ACL rules which can be the combination of various ACL rules.
Type-A I/O Modules’ ways of combinations are described in Table 540, and
non-type-A I/O Modules’ ways of combination is described in Table 541.
n
■ TP configuration is effective only for the ACL rules whose actions are permit.
