15K new interfaces visible for a single device.

15K new interfaces visible for a single device.

Hello,

I'm able to see 15K new interfaces on a single device. That device is a Cisco router with not more than 6 Interfaces on it.

What can be the issue? 

The configuration on the router is as below

ip flow-cache timeout active 1
ip flow-export source Loopback0
ip flow-export version 5
ip flow-export destination 10.1.40.70 9996

Interface FastEthernet0/0 
 ip flow ingress
 ip flow egress

Regards,
Yash
