The cpu usage is even more higher when I apply a voice ACL on the on of the switches, more than other.
The peak is at Lopri processes.
I attached the show procc cpu and sh platform health.
When I apply a ACL the cpu utilization is 90%.
In my show log I have detected only one error duplex mismatch. The network is operating normally now, but I disabled the ACL on the other switch because than the CPU spikes. The same ACL is working fine on the other switch.
