Can you paste the code which is doing the query?
No, the OF is get via NOX Virtual Test Environment setup instruction.

Subject: Re: [nox-dev] aggregate flow statistics always return 0
Are you using the OF reference code from Stanford?
Hi all,
I am using NOX Virtual Test Environment
The topology is one OpenFlow switch and two hosts.
Host 1 and host2 continually ping each other.
In monitor component, the aggregate statistics always show 0.
But, if I dump the aggregate statistics on OpenFlow switch, OpenFlow
switch did print aggregate statistics which is non-zero.
My question is why OpenFlow switch always returned 0 for aggregate
stats to NOX.
OpenFlow version is 0.8.9~1
NOX version is 0.6.0
On NOX, I issued: *./nox_core -v -i ptcp:2525 pyswitch monitor*
On OpenFlow, I issued: *./secchan nl:0 tcp:10.0.2.2:2525 &*
===== some NOX log message====
