Sample configuration that would cause problems: DEVICE=eth2.50 HWADDR=00:15:17:0B:49:B4 ONBOOT=yes TYPE=Ethernet IPADDR=10.50.0.1 NETMASK=255.255.0.0 VLAN=yes Just don't specify HWADDR for vlan. Do it only in the real physical interface. Agreed. Here's a conversation on #udev from back in July... [11:04am] haraldh: Norm, pong [11:04am] Norm: i had a RHEL question regarding udev naming interfaces using a subinterface name (eth0.14) instead of the real name (eth0), but i'm suspecting it may be due to my specifying HWADDR in ifcfg-eth0 and in ifcfg-eth0.14 [11:05am] haraldh: ouch [11:05am] haraldh: please do not do that in ifcfg-eth0.14 [11:06am] Norm: hehe [11:06am] Norm: let me tell you, when udev names your interface "eth0.14", you're in for a world of hurt [11:06am] haraldh: true [11:07am] Norm: this is a RHEL5 -> RHEL6 upgrade, in previous versions it was equally unnecessary, but didn't hurt anything [11:07am] haraldh: mmhh.. yes [11:07am] Norm: anyway, i'm hopeful that this reboot will straighten everything out [11:07am] haraldh: Norm, can you open a bugzilla for this? [11:07am] Norm: sure thing [11:07am] haraldh: so I will not forget [11:07am] haraldh: thank you! [11:07am] Norm: np, thank you! Created attachment 531275 [details]
