Nexus Ping loss

[hanwucisco]

We have two Nexus 7k used as core in a site, they are doing VPC and have portchannel between . The ping from one to other loses constantly with 0.5% percent. and I did ping from one of them to the switches that directly connect to them. the ping is also not good, similar results.

And we have another site, the topo is the same and the ping result loss is also the same.

What could be the problem?

thanks,

Han

That is because CoPP.   I have seen the same thing with 7Ks.

Here is what I would do-

Check physical media and assosciated port statistics

Check your vpc's [show vpc]

debug icmp
