Hi,
I’m working off Justin Pettit’s ‘conntrack’ tree @
https://github.com/justinpettit/ovs/tree/conntrack, and can’t seem to get marks
to work.
Here’s an example of a flow (FTP server)
===
ovs-ofctl add-flow br0
"table=3,cookie=0xb0b,priority=32000,ct_state=+new+trk,tcp,tp_dst=21
actions=ct(
Wow. - Thanks so much Jesse,
I will try this with a fresh coffee in the morning @ the office in the
morning. it's 11pm now. - can't think straight anymore.. :)

Hi Minh,
Controller could query existing flows before adding. I’m not clear why you need
to do this. Ovs-ofctl has no impact as long as you don’t use it. You can remove
the mgmt socket (/var/run/openvswitch/.mgmt) if you really want.
Thanks,
Xiao

Thanks Jesse!
I think you may be close, but it is the ovs code that is re-entering it's
self, this isn't an arp storm from a circle of traffic path, as far as i
can tell. it is an attempt to transmit a single packet.. but never gets
even the arp out to the stack at all.
you can see build_tunnel_sen

Hi Team,
I was looking a the code in multipath.c file. In function algorithm_hrw( )
assignment is done from int->short (best_link = link). It might lead to
bit truncation. Following is the code snippet for your reference.
uint32_t best_weight;
uint16_t best_link;
unsigned int link;

In OVS a callback fn is given to the sFlow library for all allocation, but
the callback (ofproto/ofproto-dpif-sflow.c:sflow_agent_alloc_cb()) just
calls "calloc()" too. This should probably be changed to xcalloc() as
defined in lib/util.c which does the right thing. Thanks for pointing
this out
Hi Team,
I was looking a the code in sfow_agent.c file in sflAlloc( ) function. This
funtion allocates memory via malloc but didn't check whether memory
allocation is successful or not.
I think there should be a check, in case malloc fails to allocate memory.

Hi Team,
I was looking a the code in learn.c file. As per my understanding atoi
function take const char * as an input argument. but in the below snippet
value is passed as argument which is char *.
} else if (!strcmp(name, "priority")) {
learn->priority = atoi(value);
} else

Hello,
I’ve searched in the documentation but i was unable to find a way to execute
some action on a packet or generate a event based on the counters of, by
example, a number of matches of a flow entry, or sent packets in a switch port.
I’ve seen that in Nicira extended match it is possible to m
Hi Xiao,
Thank you for your quick response. That means there are several ways to
insert OF flows! Then, if I insert OF rules by using ovs-ofctl and by a
controller, is there any way to ensure installed rules are not overlap or
interfere with the others? Or is there any way to only allow one way to
Hi Minh,
As far as I know, most controllers will include OpenFlow protocol
implementation. They communicate with switches by OpenFlow message. In this
way, ovs-ofctl makes no difference, it sends / receives messages via sockets
(unix, tcp, etc.). Some controller might also have OVSDB southbound
Hello,
It is easy to push OpenFlow rules to OVS by using the OVS utility such
as ovs-ofctl. Thanks all OVS developers!
However, I now want to try that function with a SDN controller and I wonder
that does the SDN controller (i.e., pox, nox or floodlight) will call
ovs-ofctl to install OF flows or
16 matches
