Hi
I have a Cisco 881 router
when enter show ip cache flow, I see this:
SrcIf SrcIPaddress DstIf DstIPaddress Pr SrcP DstP Pkts
.
.
Fa4 M.M.M.M Local X.X.X.X 32 D090 FC43 13K
.
.
Is a large amount of packets.
The Interface F4 does not have big traffic
MTU 1500 bytes, BW 2048 Kbit/sec, DLY 100 usec,
reliability 255/255, txload 3/255, rxload 49/255
I have a DMVPN Tunnel between M.M.M.M and X.X.X.X
I enter the same command in the remote peer and I don't get the traffic shown in the 881.
What this traffic means?
Thanks

In looking at your output the PR (protocol) is 32 which is in hex. Translated into decimal it is protocol 50, which is ESP. So you are probably seeing your DMVPN traffic. If the remote peer is not reporting this then I would assume that there is some difference in how NetFlow is configured on that device.

adding to what Richard said.
check whether these commands are on other device interface
ip flow ingress
ip flow engress
if these commands are not there then please enter it and then use the show command
sh ip cache flow.
sh ip cache verbose flow (details understanding of traffic)
