21.3 QoS Example
Example 1:
Enable QoS function, change the queue out weight of port to 1:1:2:2:4:4:8:8, set it in trust CoS
mode and set the default CoS value of the port to 5.
The configuration steps are listed below:
Switch#config
Switch(config)#mls qos queue weight 1 1 2 2
Switch(Config-If-Ethernet1/1)# mls qos queue wrr weight 1 1 2 2 4 4 8
8
Switch(Config-If-Ethernet1/1)#mls qos cos 5
Configuration result:
When QoS enabled in Global Mode, the egress queue bandwidth proportion of all ports is
1:1:2:2:4:4:8:8. When packets with CoS value coming in through port, it will be map to the
queue out according to the CoS value, CoS value 0 to 7 correspond to queue out 0, 0, 1, 1, 2,
2, 3, 3 respectively. If the incoming packet without CoS value, it is default to 5 and will be put in
queue 2.
Example 2:
In port ethernet1/2, set the bandwidth for packets from segment 192.168.1.0 to 10 Mb/s, with a
burst value of 4 MB, all packets exceed this bandwidth setting will be dropped.
The configuration steps are listed below:
Switch#config
Switch(config)#access-list 1 permit 192.168.1.0 0.0.0.255
Switch(config)#class-map c1
Switch(Config-ClassMap-c1)#match access-group 1
Switch(Config-ClassMap-c1)#exit
Switch(config)#policy-map p1
Switch(Config-PolicyMap-p1)#class c1
Switch(Config-PolicyMap-p1-Class-c1)#policy 10000 4000 exceed-action
drop
Switch(Config-PolicyMap-p1-Class-c1)#exit
