I updated motherboard on x240 computer node, now the ethernet interfaces show up as eth2 and eth3 previously it was eth0 and eth1.
I tried to delete
/etc/udev/rules.d/70-persistent-net.rules file but the problem still persists. On boot it says that eth3 and eth2 cannot be recognized or mapped. The new mac addresses are clearly illustrated and mapped to name files eth2 and eth3.
I did change in file ifcfg eth2 and eth3 and change its name to eth0 and eth1 respectively. But this too had little effect, do I need this change to be done in
70-persistent file as well? I.e. change name to match the entry in
Is there a way i can bring the old mapping back? Thanks.
