I have a 7600 running 12.2(33)SRE1. I was wondering why mls nde export statistics aren't incrementing.
I have the following configured:
ip flow-export source Loopback3
ip flow-export version 5
ip flow-export destination 192.168.2.200 9995
mls flow ip interface-full
no mls flow ipv6
mls nde sender
mls sampling time-based 512
I have Vlan interfaces with ip flow ingress configured.
interface Vlan804
ip address 192.168.4.1 255.255.255.252
no ip redirects
no ip unreachables
no ip proxy-arp
ip verify unicast source reachable-via any allow-default
ip flow ingress
load-interval 30
end
A show ip flow export shows me exported flows... the counters increment
RTR7600#show ip flow export
Flow export v5 is enabled for main cache
Export source and destination details :
VRF ID : Default
Source(1) 192.168.100.1 (Loopback3)
Destination(1) 192.168.2.200 (9995)
Version 5 flow records
315756904 flows exported in 10536943 udp datagrams
0 flows failed due to lack of export packet
0 export packets were sent up to process level
0 export packets were dropped due to no fib
0 export packets were dropped due to adjacency issues
0 export packets were dropped due to fragmentation failures
0 export packets were dropped due to encapsulation fixup failures
0 export packets were dropped enqueuing for the RP
0 export packets were dropped due to IPC rate limiting
0 export packets were dropped due to Card not being able to export
A show mls nde shows me nothing
RTR7600#show mls nde

Do the versions need to match? Is that what is preventing the mls nde export? Any suggestions or tips for troubleshooting this?
