Management interface changes after fedora system reboot

Hi,
By using below procedure, I have changed the interface names on Fedora17 system

[root@localhost ~]# rpm -qa | grep biosdevname
biosdevname-0.3.11-6.fc17.i686
[root@localhost ~]# rpm -e biosdevname-0.3.11-6.fc17.i686
[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# mv ifcfg-p5p1 ifcfg-eth0
[root@localhost network-scripts]# mv ifcfg-p3p1 ifcfg-eth1
[root@localhost network-scripts]# mv ifcfg-p3p2 ifcfg-eth2
[root@localhost network-scripts]# mv ifcfg-p3p3 ifcfg-eth3
[root@localhost network-scripts]# mv ifcfg-p3p4 ifcfg-eth4
## Changed the device name to resp eth interface in each ifcfg-eth file
[root@localhost network-scripts]# vim ifcfg-eth0
[root@localhost network-scripts]# vim ifcfg-eth1
[root@localhost network-scripts]# vim ifcfg-eth2
[root@localhost network-scripts]# vim ifcfg-eth3
[root@localhost network-scripts]# vim ifcfg-eth4
[root@localhost network-scripts]# reboot

After system reboot the interface name changed successfully but now facing one weird issue on Fedora17 system.
The problem is that whenever the Fedora system is rebooted the management ip address is assigned to intermittently different interfaces i.e sometimes it allocates to eth0 & sometimes to eth4 but no connectivity issue is observed.
I need it to be consistently assign to eth0 only.

If anyone have solution to above issue then pls reply

Hi shailendra,

changes won't last after reboot, you have to edit /etc/udev/rules.d/70-persistent-net.rules file to make changes permanent.

[root@centos ~]# vim /etc/udev/rules.d/70-persistent-net.rules

# PCI device 0x14e4:0x1677 (tg3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:14:38:c7:f4:5c", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x1186:0x4c00 (skge)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:11:95:fd:d9:3e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

since mine is centos i'll have eth*, so you have to find p5p1 and replace it eth

Hi Gil,
Thanks for the reply.
Fedora system doesn't have below file
/etc/udev/rules.d/70-persistent-net.rules

Best Regards,
