Hi Flavio, this came up during OVN issue prioritization. Given the age of this bug report, do you know if this is still relevant? Hello Mark, Flavio is not working on this project anymore. I can confirm that we are still facing that issue in OpenStack environments. Hi there, Just as an FYI: We are running into this in ovn-kubernetes, too: https://bugzilla.redhat.com/show_bug.cgi?id=2051954#c11 - Andreas tested with following script: systemctl start openvswitch systemctl start ovn-northd ovn-nbctl set-connection ptcp:6641 ovn-sbctl set-connection ptcp:6642 ovs-vsctl set open . external_ids:system-id=hv1 external_ids:ovn-remote=tcp:20.0.177.25:6642 external_ids:ovn-encap-type=geneve external_ids:ovn-encap-ip=20.0.177.25 systemctl restart ovn-controller ovn-nbctl ls-add ls1 ovn-nbctl lsp-add ls1 ls1p1 ovn-nbctl lsp-set-addresses ls1p1 "00:00:00:01:01:01 192.168.1.1 2001::1" ovs-vsctl add-port br-int ls1p1 -- set interface ls1p1 type=internal external_ids:iface-id=ls1p1 ip netns add ls1p1 ip link set ls1p1 netns ls1p1 ip netns exec ls1p1 ip link set ls1p1 address 00:00:00:01:01:01 ip netns exec ls1p1 ip link set ls1p1 up ip netns exec ls1p1 ip addr add 192.168.1.1/24 dev ls1p1 ip netns exec ls1p1 ip addr add 2001::1/64 dev ls1p1 ip netns exec ls1p1 ip route add default via 192.168.1.254 dev ls1p1 ip netns exec ls1p1 ip -6 route add default via 2001::a dev ls1p1 ovn-nbctl meter-add meter0 drop 50 pktps ovn-nbctl --log --severity=alert --name=bz1939524 --meter=meter0 acl-add ls1 to-lport 1000 'icmp4' drop ovn-nbctl --wait=hv sync ovs-ofctl -O OpenFlow15 dump-meters br-int band_id=$(ovn-nbctl list meter_band | awk '/_uuid/{print $3}' ) for meter in 30 20 10 -1 5 do ovn-nbctl set meter_band $band_id rate=$meter ovn-nbctl --wait=hv sync ovs-ofctl -O OpenFlow15 dump-meters br-int done reproduced on ovn-2021-21.12.0-32.el8: + ovn-nbctl set meter_band 4f49cde0-febe-4dac-88d4-8e34657b6fcb rate=30 + ovn-nbctl --wait=hv sync + ovs-ofctl -O OpenFlow15 dump-meters br-int OFPST_METER_CONFIG reply (OF1.5) (xid=0x2): meter=1 pktps stats bands= type=drop rate=50 + for meter in 30 20 10 -1 5 + ovn-nbctl set meter_band 4f49cde0-febe-4dac-88d4-8e34657b6fcb rate=20 + ovn-nbctl --wait=hv sync + ovs-ofctl -O OpenFlow15 dump-meters br-int OFPST_METER_CONFIG reply (OF1.5) (xid=0x2): meter=1 pktps stats bands= type=drop rate=50 <==== rate not changed ...
