Hi, everybody
I’m studying QoS, such as Policing. And I have one question: Why packets drop (violated), if interface rate not exceeded 128 000 bps, I don’t understand that moment ?
I build lab on EVE-NG. Topology is very simple. R1 and R2 routers directly connected (ethernet 0/0) (subnet 10.1.12.0/24). Policing (single rate and three color) configured on R2:
interface Ethernet0/0
ip address 10.1.12.2 255.255.255.0
load-interval 30
service-policy input PM-SINGLE-RATE-THREE-COLOR
end
!
class-map match-all CM-ICMP
match protocol icmp
policy-map PM-SINGLE-RATE-THREE-COLOR
class CM-ICMP
police cir 128000
conform-action transmit
exceed-action set-dscp-transmit default
violate-action drop
and R1 config:
interface Ethernet0/0
ip address 10.1.12.1 255.255.255.0
end
P.S. I interrupted ping when was 1052
