Hi,
While i am trying to drop packages, i interfere either
strange error or totally wrong port stats. Is there anyone who can guide
me or idea about this issue. I am using dpdk with ovs. Dpdk version
is*2.2.0* and ovs is *1cef5fff1da194c67e4c502b376b8cffdec79e8b* commit
on master branch.
I have 2 dpdk port :
1(dpdk0): addr:3c:a8:2a:5b:63:84
config: 0
state: 0
current: 1GB-FD
supported: 10MB-FD
speed: 1000 Mbps now, 10 Mbps max
2(dpdk1): addr:3c:a8:2a:5b:63:85
config: 0
state: 0
current: 1GB-FD
supported: 10MB-FD
speed: 1000 Mbps now, 10 Mbps max
LOCAL(br0): addr:3c:a8:2a:5b:63:84
config: PORT_DOWN
state: LINK_DOWN
current: 10MB-FD COPPER
speed: 10 Mbps now, 0 Mbps max
[root@localhost ovs]# ovs-ofctl dump-ports br0
OFPST_PORT reply (xid=0x2): 3 ports
port 1: rx pkts=0, bytes=0, drop=0, errs=0, frame=?, over=?, crc=?
tx pkts=0, bytes=0, drop=0, errs=0, coll=?
port LOCAL: rx pkts=0, bytes=0, drop=0, errs=0, frame=0, over=0, crc=0
tx pkts=0, bytes=0, drop=0, errs=0, coll=0
port 2: rx pkts=0, bytes=0, drop=0, errs=0, frame=?, over=?, crc=?
tx pkts=0, bytes=0, drop=0, errs=0, coll=?
At this point i am adding a simple flow : ovs-ofctl -OOpenFlow13
add-flow br0 'table=0, priority=100, in_port:2, action='
NXST_FLOW reply (xid=0x4):
cookie=0x0, duration=5.118s, table=0, n_packets=0, n_bytes=0,
idle_age=5, priority=100,in_port=2 actions=drop
cookie=0x0, duration=65.077s, table=0, n_packets=0, n_bytes=0,
idle_age=65, priority=0 actions=NORMAL
And i am sending packages to port 2 with tcpreplay. After sending
packages, in port stats i can see sent package count but no dropped
packages.
[root@localhost ovs]# ovs-ofctl dump-ports br0
OFPST_PORT reply (xid=0x2): 3 ports

port LOCAL: rx pkts=0, bytes=0, drop=0, errs=0, frame=0, over=0, crc=0
tx pkts=0, bytes=0, drop=0, errs=0, coll=0
* port 2: rx pkts=6270, bytes=6043021, drop=0,* errs=0, frame=?,
over=?, crc=?
tx pkts=0, bytes=0, drop=0, errs=0, coll=?
[root@localhost ovs]# ovs-ofctl dump-flows br0
NXST_FLOW reply (xid=0x4):
cookie=0x0, duration=33.855s, table=0, n_packets=6270,
n_bytes=6043021, idle_age=21, priority=100,in_port=2 actions=drop
cookie=0x0, duration=47.501s, table=0, n_packets=0, n_bytes=0,
idle_age=47, priority=0 actions=NORMAL
Any idea why i am interfering drop issue ?
Thanks in advance,
kursat
