To configure persistent interface names for network devices

1Navigate to the hotplug file in the /etc/sysconfig directory:

# cd /etc/sysconfig

2Open the hotplug file in an editor.

3Set HOTPLUG_PCI_QUEUE_NIC_EVENTS to yes:

HOTPLUG_PCI_QUEUE_NIC_EVENTS=yes

4Run the command:

ifconfig -a

5Make 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:

■If a file named /etc/sysconfig/network/ifcfg-eth-id-mac, where mac is the 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 the contents of that 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
