Description Olaf Hering 2019-08-30 10:00:52 UTC

With these files, wicked does not get the correct ipv4 address in Tumbleweed, but it does so in Leap, SLE15, SLE12:

stein-schneider:/etc/sysconfig/network # head ifcfg-*
==> ifcfg-br0 <==
BOOTPROTO='dhcp'
BRIDGE='yes'
BRIDGE_FORWARDDELAY='0'
BRIDGE_PORTS='eth0'
BRIDGE_STP='off'
STARTMODE='auto'

==> ifcfg-eth0 <==
BOOTPROTO='none'
STARTMODE='auto'

It gets some random address from the pool, instead of the assigned address for this specific MAC.

With just this file it gets the expected address:
==> /etc/sysconfig/network/ifcfg-eth0 <==
BOOTPROTO='dhcp'
STARTMODE='auto'
DHCLIENT_CLIENT_ID='01:00:26:55:23:e5:46'


Appending the clientid to ifcfg-br0 makes zero difference. It just gets another random address from the pool.

I confirm, that the bridges stopped working with IPv4

Comment 2 Dead Mozay 2019-09-09 05:16:37 UTC

Checked with NetworkManager, same problem

Comment 3 Marius Tomaschewski 2020-03-20 13:56:19 UTC

This is about the client-id change, see also:

Unlikely.

dup of some systemd bug. Still unfixed after one year...

Comment 5 Olaf Hering 2020-03-20 14:43:09 UTC

systemd bug.
