Control Plane Protection (Policing) configuration on Catalyst 3850
I need to block ICMP requests from being received by the switch. And there is no 'control-plane' configuration mode, which I was going to use for this. How can I configure this feature or apply another for my purpose?
+1 I'm just looking in to this and have some questions on my own. The 3650 and 3860 seems to be missing the "control-plane" by design. There's some default settings on the box for control plane protection, that you can change. The command "cpp" in global mode configures some queues. List the queues with:
show platform qos queue stats internal cpu policer
There no specific ICMP request queue, not that i see anyway. Sorry! Maybe the ICMP GEN is the one that you could look in to....but what else is then dropped?
I can't find any more information about this. If i disable something, is it dropped or just in some default queue? if i set police 0 (zero) is the queue dropping everything? What stuff is put in thees detained queues....
