The highest process cause the high CPU utilization is "IP input". We take many times to find specific source interface and disable it to decrease CPU utilization.
The netdr tool can speed up to find the root cause of high CPU utilization, it is better for us if we can export the result and analyze it by protocol analyzer.

Hi,
My Catalyst 6509 with Supervisor Engine 2T have high cpu utilization issue, we hope to know which traffic imapct and cause the high CPU utilization.
As I know the Supervisor Engine 2T not support the "monitor session type local" command. Is there other method to capture the traffic hit to CPU, and I can export and analyze it by packet analyze tool ( wireshark )?

Hi,
We have find the configuration guide ( http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/nx-os/unicast/configuration/guide/b-7k-Cisco-Nexus-7000-Series-NX-OS-Unicast-Routing-Configuration-Guide-Release/n7k_unicast_config_isis.html ) mention :
" Cisco NX-OS supports the Equal Cost Multiple Paths (ECMP) feature with up to 16 equal-cost paths in the IS-IS route table and the unicast RIB"
Does it support unequal cost load balance for IS-IS?

Jackson Ku

Dear All,
The Cisco 1832i datasheet mention "If 802.3af PoE is the source of power, the USB port is disabled".
The power source we used is 803.2af PoE, but the access point seems reload unexpectedly. We change the power source to 802.3at PoE to resolve this issue. Please help to advice me how to disable Aironet 1832i USB port manually?
