[c-nsp] Measuring Traffic on Logical interfaces on Layer 3 Switches

[Terry Rupeni]

Hi All,

 

We are grabbing SNMP traffic data off an Cat4500 Layer 3 interface (e.g. int
vlan 100). I don't  think this is a true measure of in/out traffic for a
layer 3 interface due to the nature of CEF? Am I correct in this statement?

 

Appreciate your opinions.

 

Thanks 

 

Terry
