I'm seeing a strange problem with vlan configs on core 5 with the latest updates applied. Basically it seems that on boot, Fedora is mixing up the vlan interfaces. I have two vlans, 41 and 46. On boot, fedora seems to be putting eth1.46 into vlan 41 and therefore things are failing on boot. My work around at the moment is: vconfig rem eth1.46 41 Then ifup eth1.46 ifup eth1.44 Here is my ifcfg-eth* files: more ifcfg-eth1* :::::::::::::: ifcfg-eth1 :::::::::::::: # Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express DEVICE=eth1 BOOTPROTO=dhcp DHCPCLASS= HWADDR=00:17:A4:3F:27:76 ONBOOT=yes :::::::::::::: ifcfg-eth1.41 :::::::::::::: # Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express DEVICE=eth1.41 BOOTPROTO=dhcp DHCPCLASS= HWADDR=00:17:A4:3F:27:76 ONBOOT=yes VLAN=yes :::::::::::::: ifcfg-eth1.46 :::::::::::::: # Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express DEVICE=eth1.46 BOOTPROTO=dhcp DHCPCLASS= HWADDR=00:17:A4:3F:27:76 ONBOOT=yes VLAN=yes Am I doing something wrong? I didn't notice this problem with vanilla core 5. Only saw it after updates. On boot a failure with look like this: [root@p07ir01 network-scripts]# cat /proc/net/vlan/config VLAN Dev name | VLAN ID Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD eth1.46 | 41 | eth1 Thanks -jeremy
