Hi folks,
after the upgrade to Debian 11 some network interfaces in my
Dell R740 got renamed. Before:
# lshw -class network -short
H/W path Device Class Description
========================================================
/0/2/0 eno1 network Ethernet Controller 10G X550T
/0/2/0.1 eno2 network Ethernet Controller 10G X550T
/0/3/0 eno3 network I350 Gigabit Network Connection
/0/3/0.1 eno4 network I350 Gigabit Network Connection
/0/103/0 ens3f0 network I350 Gigabit Network Connection
/0/103/0.1 ens3f1 network I350 Gigabit Network Connection
After:
# lshw -class network -short
H/W path Device Class Description
=======================================================
/0/2/0 eno1 network Ethernet Controller 10G X550T
/0/2/0.1 eno2 network Ethernet Controller 10G X550T
/0/3/0 eno3 network I350 Gigabit Network Connection
/0/3/0.1 eno4 network I350 Gigabit Network Connection
/0/103/0 enp94s0f0 network I350 Gigabit Network Connection
/0/103/0.1 enp94s0f1 network I350 Gigabit Network Connection
How comes? AFAIR these predictable interface names had been introduced
to get *stable* names, if the hardware is changed. Since it is more
likely to get a kernel upgrade than new network hardware I wonder of the
predictable names could be made even more predictable?
Old kernel was 4.19.0-18-amd64, new kernel is 5.10.0-14-amd64.
/lib/systemd/network/99-default.link is
[Match]
OriginalName=*
[Link]
NamePolicy=keep kernel database onboard slot path
AlternativeNamesPolicy=database onboard slot path
MACAddressPolicy=persistent
Every helpful comment is highly appreciated.
