IP Flow in GRE Tunnel

[zulkarnainkamaludin]

Hi,

I have built multiple GRE tunnel and one of the tunnel has been enabled ip flow. The confguration is as below.

interface xxx

ip address xxxx

ip mtu 1400

ip tcp adjust-mss 1360

ip flow ingress

keepalive 5 3

tunnel source xxx

tunnel destination xxxx

When I issue the command 'show ip cache flow', what can I see i mainly the GRE Tunnel activity whereas the other traffic seem very little. How I want to eliminate seeing the GRE Tunnel activities in the report?

Hi,

Thanks for reply. What I want to get is the meaningful traffic travelling into the GRE Tunnel. What I have seen is when I enable the ip flow ingress comand in the tunnel interface, I still see the traffic of Tunnel as below:

SrcIf         SrcIPaddress    DstIf         DstIPaddress    Pr SrcP DstP  Pkts

Tuxxxx        xxxx            xxx           xxx             2F 0000 0000    52

Tuxxxx        xxxx            xxx           xxx             01 0000 0000     1

SrcIf         SrcIPaddress    DstIf         DstIPaddress    Pr SrcP DstP  Pkts

Tuxxxx        xxxx            xxx           xxx             2F 0000 0000    52

Tuxxxx        xxxx            xxx           xxx             01 0000 0000     1

So I wanted to remove this from my report. Is there anyway to disable the traffic generate by Tunnel interface to the ip flow?

Dear Zulkarnain;

what I understood from your post is that you dont want to see the traffic statistics/reports of tunnel interface;

so type

interface tunnel1

no ip flow ingress
