Hallo,
Is there a way to simulate a DoS attack in CML? I am doing a lab on CoPP and an attack is required but I am unable to generate this. Thanks.

Config CoPP rate
And ping the device 10000
This will test your CoPP ' it must drop this high rate of ping traffic

Hi @MHM Cisco World Thanks for the quick response but I don't quite understand what you mean. Above is the simple topology and the attcket should be from extern. Could you clarify more.

From extern ping 10000 to R1

you can use like kali linux as attacker:
check kali Linux integration with CML

@MHM Cisco World Thank you, I have used a router to send many icmp packets and a few are dropping , which is what I wanted to test. Thanks so much for always being helpful.
@balaji.bandi Thanks for the suggestion. It will require a bit of effort to get it done but I have found a workaround.

@MHM Cisco World Just a curious question. I have explicitly denied icmp packets in the access-list on R2 and applied it in the control plane. However, when R1 pings R2, it only drops a few packets. Why is that so? Part of the config is below:
-------on R2-----------
ip access-list extended ICMP
deny icmp any any
class-map match-all ICMPC
match access-group name ICMP
policy-map ICMPP
class ICMPC
police 8000 conform-action transmit exceed-action drop
control-plane
service-policy input ICMPP
_______________________________________________________________________
R1#ping 192.168.12.2 repeat 100
Type escape sequence to abort.
Sending 100, 100-byte ICMP Echos to 192.168.12.2, timeout is 2 seconds:
!!!!!!!!!!!!!.!!!!!!!!!!!!!.!!!!!!!!!!!!!.!!!!!!!!!!!!!.!!!!!!!!!!!!!.
!!!!!!!!!!!!!.!!!!!!!!!!!!!.!!
Success rate is 93 percent (93/100), round-trip min/avg/max = 1/1/1 ms

Hi friend
policy-map ICMPP
class ICMPC
police 4000 conform-action transmit exceed-action drop
Change the police to be 4000 and check ping loss you need to see now more ping loss
