Yes. That makes sense. That is what I did for the taps. But how do I capture packets coming in/out of a gre port(since this is not a real interface on the machine?) Thanks. On Fri, Aug 3, 2012 at 10:39 AM, Jesse Gross wrote: > On Fri, Aug 3, 2012 at 10:36 AM, Aishwarya wrote: > > Ok. Thanks. I

Ok. Thanks. Is there a way to check what ports a particular packet is being sent on? Like a capture functionality on a port? When I run tcpdump on br0 interface, I sometimes don't see some packets going through that at all. For eg, in my setup I have 2 hosts. On host1, I have a vm1 ip 192.168.0.2/2

[ovs-discuss] how to fliter arp requests from being forwarded to the gre ports

2012-08-02 Thread Aishwarya
Hi, I am trying to prevent arp requests(for a particular ip) from being forwarded on the gre ports. Is there a way to add a flow to do this? I don't see anything explicit in ovs-ofctl to do this. Was wondering if it is possible. Conversely, it would help if there is a way to output arp requests on
