set mef-envelopeId 20 envelope-rank 5
end

#Sixth Meter Creation

configure terminal
meter 60
meter-type mefBandwidthSharing  cir 1000000 cbs 4194304 eir 2000000 ebs 4194304 coupling-flag disable
set mef-envelopeId 20 envelope-rank 6
end

#Seventh Meter Creation

configure terminal
meter 70
meter-type mefBandwidthSharing  cir 1000000 cbs 4194304 eir 2000000 ebs 4194304 coupling-flag enable
set mef-envelopeId 20 envelope-rank 7
end

#Eight Meter Creation

configure terminal
meter 80
meter-type mefBandwidthSharing  cir 1000000 cbs 4194304 eir 2000000 ebs 4194304 coupling-flag disable
set mef-envelopeId 20 envelope-rank 8
end

7. Configure the QOS policy-map with actions.

configure terminal
policy-map 10
set meter 10 exceed-action cos-transmit-set 7 violate-action drop
set policy class 10 default-priority-type none
end
configure terminal
policy-map 20
set meter 20 exceed-action cos-transmit-set 6 violate-action drop 
set policy class 10 default-priority-type none 
end
configure terminal
policy-map 30
set meter 30 exceed-action cos-transmit-set 5 violate-action drop 
set policy class 10 default-priority-type none 
end
configure terminal
policy-map 40
set meter 40 exceed-action cos-transmit-set 4 violate-action drop 
set policy class 10 default-priority-type none 
end
configure terminal
policy-map 50
set meter 50 exceed-action cos-transmit-set 3 violate-action drop
set policy class 10 default-priority-type none
end
configure terminal
policy-map 60
set meter 60 exceed-action cos-transmit-set 2 violate-action drop 
set policy class 10 default-priority-type none 
end
configure terminal
policy-map 70
set meter 70 exceed-action cos-transmit-set 1 violate-action drop 
set policy class 10 default-priority-type none 
end
configure terminal
policy-map 80
set meter 80 exceed-action cos-transmit-set 0 violate-action drop 
set policy class 10 default-priority-type none 
end

8. Configure QOS envelope.
   #Envelope 1

configure terminal
mef-envelope 20 
set envelope-type priority-based coupling-flag enable envelope-name EVC1 
set envelope enable 
end

9. Enable the meter stats.

configure terminal
set meter-stats enable meter-id 10
set meter-stats enable meter-id 20
set meter-stats enable meter-id 30
set meter-stats enable meter-id 40
set meter-stats enable meter-id 50
set meter-stats enable meter-id 60
set meter-stats enable meter-id 70
set meter-stats enable meter-id 80
end

10. Configure envelope rank.

configure terminal
set mef dot1p-priority 0 envelope-rank 1
set mef dot1p-priority 1 envelope-rank 2
set mef dot1p-priority 2 envelope-rank 3
set mef dot1p-priority 3 envelope-rank 4
set mef dot1p-priority 4 envelope-rank 5
set mef dot1p-priority 5 envelope-rank 6
set mef dot1p-priority 6 envelope-rank 7
set mef dot1p-priority 7 envelope-rank 8
end

MEF 10.3 priority base interlaced method, Green packet remarking is not supported (the configuration of green remarking priority values is not applicable when metering entry is color aware) and only yellow, red packets remarking is supported. Red packet remarking should be configured the same as yellow or drop.
