My pair of Nexus 6K started giving a poor rate of response to ping messages a couple of days ago. Any SVI's IP address seeing 10 to 30% loss. These pings can come from any attached device. After some googling I came across an article discussing COPP and the management plane. As you can see the violation counts are enormous. Can someone comment on what all might be affected by all of these violations? The glean, the managemenet, the ICMP? 1 Trillion glean violations? What's that about??

ICMP violations increment around 9MB every five minutes. Advice appreciated!
