21.5. 流量控制

21.5.1. 基于接口

cir 它必须是64的倍数

qos lr outbound cir 64 64Kbps

qos lr outbound cir 1024 1Mbps

[H3C-GigabitEthernet1/0/18]di this
#
interface GigabitEthernet1/0/18
 port access vlan 9
 qos lr outbound cir 64 cbs 4000
 qos apply policy 20 inbound
 dhcp-snooping trust
#
return
			

察看状态

display qos lr interface GigabitEthernet 1/0/18
			

21.5.2. 基于 ACL

acl number 3009
rule 0 permit ip source 192.168.9.0 0.0.0.255

traffic classifier traffic-limit
if-match acl 3009

traffic behavior traffic-limit

Warning: CBS is smaller than (100/16)CIR, and this maybe effect network traffic burst.
