Red Hat Bugzilla – Bug 197162
1 Ethernet interface is not named properly on a system with 4 interfaces using the same driver when HWADDR is specified for all of them
Last modified: 2014-03-16 23:00:17 EDT
Description of problem: I have a system with 2 NICs integrated onto the
motherboard, and a dual-port PCI-X card for a total of 4 interfaces. The
motherboard's and PCI-X card's Ethernet chipsets are slightly different, but
both use the e1000 driver. I have specified HWADDR for the 4 interfaces so as
to ensure consistent naming among them (also so that the physical layout on the
back of the server has the same device names in the same positions as other
servers it will sit near).
When I boot, 3 of the interfaces are named properly, but the 4th is named
"dev#####", where "#####" is a random number. Unlike a previous, similar bug,
the number does not change every time I run ifconfig; it does change when I
reboot, however. So, for example, I may end up with Ethernet interfaces named
eth0, eth1, eth3, and dev4173.
The system in question is a Dell PowerEdge 1850.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Specify HWADDR lines for each interface in a system as described above.
2. Examine the output of "ifconfig -a" to see the device names.
One interface is named "dev#####", where ##### is a random number specific to
that boot, rather than the name corresponding to
All interfaces should be named "eth#" corresponding to how they are specified in
the above configuration files.
Please try the updates-testing initscripts.
Fixed in 8.31.2-1.
I then added another dual-port e1000 NIC, and the new ports get dev##### names,
although now there are more digits in the ##### part. For example: dev1804289383
Do you have HWADDR=XXXX in the ifcfg files? Are the ifcfg files actually named
No, they're named like so, with HWADDR specified like so (except with real MACs):
# grep HWADDR ifcfg-eth*
Hm. Does 8.31.4-1 help at all (it's currently in updates-testing, and does fix
Same results with 8.31.4-1.
Same also with 8.31.5-1.
Do the interfaces that get their names changed to dev* have ONBOOT=yes in the
This probably happens because the dev* interfaces do not get configured on boot
and they have been renamed to free up the names of those interfaces that *do*
get configured on boot. Since there was no other configuration done on them
during boot apart from changing the name to something temporary, they just
stayed with the temporary name.
