Hi everyone,
As per my understanding the CPU usage of any L3 switch will increase if the switch is having two different configurations which consumes cpu processes like NAT and PBR in same interface.

Please correct me if i am wronge.
Here my doubt is, in one of my switch(6504 model) is having these type of configuration which is show below, but it doesn't have cpu high utilization as of now. Do i need to remove any of the configuration from this to avoid problem which may happen in future? Or these configuration will run fine with out utilizing high cpu?
Can anyone share your knowledge here...
interface Vlan301
ip address x.x.x.x 255.255.255.0
ip helper-address x.x.x.x
ip helper-address y.y.y.y
ip directed-broadcast
ip accounting output-packets
ip nat inside
ip flow ingress
ip pim sparse-mode
ip igmp static-group x.x.x.x
ip cgmp
no ip mroute-cache
end
interface GigabitEthernet2/6
ip address x.x.x.x 255.255.255.252

end
