To configure persistent interface names for network devices
1
Navigate to the hotplug file in the /etc/sysconfig directory:
# cd /etc/sysconfig
2
Open the hotplug file in an editor.
3
Set HOTPLUG_PCI_QUEUE_NIC_EVENTS to yes:
HOTPLUG_PCI_QUEUE_NIC_EVENTS=yes
4
Run the command:
ifconfig -a
5
Make sure that the interface name to MAC address mapping remains same
across the reboots.
Symantec recommends adding the PERSISTENT_NAME entries to the
configuration files for all the network interfaces (including the network
interfaces that are not used).
For each ethernet interface displayed, do the following:
■ Ifafilenamed /etc/sysconfig/network/ifcfg-eth-id-mac,wheremacisthe
hardware address of that interface, does not exist, then do the following:
Create the file.
If a file exists for the same network interface with the name
/etc/sysconfig/network/ifcfg-ethX,then copy thecontents ofthat file into
the newly created file. The variable ethX represents the interface name.
■ Add the following line at the end of the file
/etc/sysconfig/network/ifcfg-eth-id-mac.
PERSISTENT_NAME=ethX
where ethX is the interface name.
For example:
# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:02:B3:DB:38:FE
inet addr:10.212.99.30 Bcast:10.212.99.255
