Hi,
thank you for your reply.
Actually I didn't need to use dpdk, I just had to set datapath to netdev - as
you said.
However I'm facing another problem now.
I tried to setup a drop meter with the following command :
ovs-ofctl -O Openflow13 add-meter s1 meter=1,kbps,bands=type=drop,rate=1000
I tested it and it worked fine.
then I tried to setup a dscp-remark meter :
ovs-ofctl -O Openflow13 add-meter br1
meter=1,kbps,band=type=dscp_remark,rate=1000,prec_level=1
and I got te following error :
OFPT_ERROR (OF1.3) (xid=0x2): OFPMMFC_BAD_BAND
OFPT_METER_MOD (OF1.3) (xid=0x2): ADD meter=1 kbps bands=
type=dscp_remark rate=1000 prec_level=1
According to Openflow documentation OFPMMFC_BAD_BAND indicates that the band is
unsupported.
my question is : does OVS 2.8.1 fully implement meter, or just the drop band ?
Or is my command incorrect (I successfully tested it with two other type of
switches) ?
Regards

Objet: Re: [ovs-discuss] Cannot install meter
Is used DPDK create bridge br0?
"The "meter" action is now supported noly in the userspace datapath", not
supported in kernel space.
can you find config "dpdk-init=true" in open-vswitch table's other_config.
And the datapath_type of bridge br0 needs to be similar to netdev, not system.
such as:
