Default NetFlow Sampling Rate

Hello, I'm trying to figure out what the default netflow sampling rate is on a Cisco 7613 router. I understand that netflow sampling is only for ingress in the 7613 platform?

 

Configuration:

interface g0/0

Ip flow ingress

Ip flow egress

!

Ip flow-export source Vlan300

Ip flow-export version 9

Ip flow-export destination 192.168.21.99 2055

 

From the above configuration, what would be the default sampling rate, 1:1?

I have not configured ip flow-sampling-mode packet-interval to provide a specific value. Also, I have not configured ip route-cache flow sampled on the interface.

Any information is greatly appreciated!

Thanks in advance!

This means no packet or flow sampling is taking place and all traffic is created for NetFlow.

On Cisco 7600 series routers, there are two types of NetFlow sampling - NetFlow traffic sampling and NetFlow flow sampling. NetFlow traffic sampling is supported only on the MSFC for software switched packets. NetFlow flow sampling is available on the PFCs and DFCs installed in the router. You will need to configure/enable them to have sampling for your NetFlow.
