EES4710BD 10 Slots L2/L3/L4 Chassis Switch
the port in trust CoS mode without changing DSCP value, and set the default CoS value of the port
to 5.
The configuration steps are listed below:
SWITCH#CONFIG
Switch(Config)#mls qos
Switch(Config)#interface ethernet 1/1
Switch(Config-Ethernet1/1)#wrr-queue bandwidth 1 1 2 2 4 4 8 8
Switch(Config-Ethernet1/1)#mls qos trust cos pass-through dscp
Switch(Config-Ethernet1/1)#mls qos cos 5
Configuration result:
When QoS enabled in Global Mode, the egress queue bandwidth proportion of Ethernet port 1/1 is
1:1:2:2:4:4:8:8. When packets have CoS value coming in through Ethernet port 1/1 , they will be
map to the queue according to this value. CoS values range from 0 to 7 and correspond to queue out
1, 2, 3, 4, 5, 6, 7, 8, respectively. If the incoming packet has no CoS value, it is by default 5 and will
be put in queue 6. All passing packets would not have their DSCP values changed.
Scenario 2:
In Ethernet port 1/2, set the bandwidth for packets from segment 192.168.1.0 to 10 Mbps, with a
burst value of 4 MB and all packets exceeding 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)#mls qos
Switch(Config)#class-map c1
Switch(Config-ClassMap)#match access-group 1
Switch(Config-ClassMap)# exit
Switch(Config)#policy-map p1
Switch(Config-PolicyMap)#class c1
Switch(Config--Policy-Class)#police 10000 4000 exceed-action drop
Switch(Config--Policy-Class)#exit
Switch(Config-PolicyMap)#exit
Switch(Config)#interface ethernet 1/2
Switch(Config-Ethernet1/2)#service-policy input p1
Configuration result:
