Description of problem:
OVN ovs-configuration moves the default device into br-ex. We copy the nmcli DHCP settings from the default device to br-ex.
++ nmcli --get-values ipv4.dhcp-client-id conn show a661c652-5ada-3efd-9deb-f73f9d08a896 + dhcp_client_id=
nmcli does not seem to show the actual current DHCP values.
We set NetworkManager values in /etc/NetworkManager/conf.d/ files for DHCP according to https://access.redhat.com/solutions/6747451
nmcli issue is an NetworkManager issue https://bugzilla.redhat.com/show_bug.cgi?id=2152601
There may be ovs-configuration workarounds
Version-Release number of selected component (if applicable):
4.13.0-0.nightly-2022-12-07-144237
How reproducible:
Always
Steps to Reproduce:
Following https://access.redhat.com/solutions/6747451
1.
cat <<EOF > /etc/NetworkManager/conf.d/99-client-id.conf
[connection-bond0]
match-device=interface-name:=bond0,interface-name:=br-ex
ipv4.dhcp-client-id=01:$(cat /sys/class/net/enp5s0/address)
ipv6.dhcp-duid=00:03:00:01:$(cat /sys/class/net/enp5s0/address)
EOF
2. reboot
3. nmcli --get-values ipv4.dhcp-client-id conn show
4. nmcli c show bond0 | grep 'dhcp.*id'
5. journalctl -u ovs-configuration | grep dhcp
Actual results:
# nmcli --get-values ipv4.dhcp-client-id conn show bond0 | od -c 0000000 \n 0000001 # nmcli c show bond0 | grep 'dhcp.*id' ipv4.dhcp-client-id: -- ipv4.dhcp-iaid: -- ipv4.dhcp-vendor-class-identifier: -- ipv6.dhcp-duid: -- ipv6.dhcp-iaid: -- The TRACE logs show actual values Dec 09 00:39:48 master-0-0 NetworkManager[1373]: <debug> [1670546388.9265] CONFIG: ipv4.dhcp-client-id=mac Dec 09 00:39:48 master-0-0 NetworkManager[1373]: <debug> [1670546388.9265] CONFIG: ipv6.dhcp-duid=ll Dec 09 00:39:48 master-0-0 NetworkManager[1373]: <debug> [1670546388.9265] CONFIG: ipv6.dhcp-iaid=mac Dec 09 00:39:48 master-0-0 NetworkManager[1373]: <debug> [1670546388.9265] CONFIG: ipv4.dhcp-client-id=01:52:54:00:56:88:e5 Dec 09 00:39:48 master-0-0 NetworkManager[1373]: <debug> [1670546388.9265] CONFIG: ipv6.dhcp-duid=00:03:00:01:52:54:00:56:88:e5 Dec 09 00:40:10 master-0-0 NetworkManager[1373]: <debug> [1670546410.3974] device[2818202ed4949e8f] (bond0): ipv4.dhcp-client-id: use "01:52:54:00:56:88:e5" client ID: 01:52:54:00:56:88:e5 Dec 09 00:40:12 master-0-0 NetworkManager[1373]: <debug> [1670546412.1798] device[2818202ed4949e8f] (bond0): ipv6.dhcp-iaid: using 7424379 (0x0071497b) IAID (str: 'mac', explicit 1) Dec 09 00:40:12 master-0-0 NetworkManager[1373]: <debug> [1670546412.1798] device[2818202ed4949e8f] (bond0): ipv6.dhcp-duid: generate 00:03:00:01:52:54:00:56:88:e5 DUID '00:03:00:01:52:54:00:56:88:e5' (enforcing) Dec 09 00:40:12 master-0-0 NetworkManager[1373]: <trace> [1670546412.1798] dhcp6 (bond0): duid: set 00:03:00:01:52:54:00:56:88:e5
Expected results:
# nmcli c show bond0 | grep 'dhcp.*id'
ipv4.dhcp-client-id: 01:52:54:00:56:88:e5
ipv4.dhcp-iaid: --
ipv4.dhcp-vendor-class-identifier: --
ipv6.dhcp-duid: 00:03:00:01:52:54:00:56:88:e5
ipv6.dhcp-iaid: --
br-ex is configured with the actual DHCP setting in use.
