There's a mobile version of our website.
We have two c4500 with above characteristics.
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.
Thanks in advance.
I have attached another show cpu and platform output with the 70% usage. The ACL is not active, but still big usage.
The process is K2CpuMan Review and K2AccelPacketMan: Tx are using more then used to.
The proccess K2CpuMan has greatly devolved to a normal stage when I typed in the comand:
no ip unreachables on voice vlan interface
I am reading now on what are the side effects of this command.
This command stopped sending back to the cpu ICMP packets for the denied packets in the ACL.
That used a lot of cpu utilization.
Any suggestion is much appreaciated.
