Fedora15 will adopt a new network device naming system

The developer of Fedora, Matt Domsch, said that starting from Fedora 15, the conventional ethX method will no longer be used to name the ethernet card device. A new Network Device Naming system Consistent Network Device Naming (CNDN) is being developed for Fedora 15 ). In Linux, ethX is often used to name Ethernet devices. Generally, a desktop computer has only one Ethernet port named eth0. However, the server generally has multiple Ethernet ports. For example, if there are four ports, they will be named eth0, eth1, eth2, and eth3 respectively. The disadvantage of this naming method is that network devices cannot get the same names each time they start, and they may be assigned names in any order. After a new Nic is inserted in the PCI slot, the names will become increasingly messy. The new naming method CNDN will use different naming methods for network devices. The NIC in the PCI slot and the network in the motherboard will have different prefixes.

The new naming rules are as follows:

· Em [1-N] is used for built-in Nic devices on the motherboard.

· Pci # used for PCI Nic

· NPAR & SR-IOV device suffix _, from 0 .. N depending on the number of Partitions or Virtual Functions exposed on each port.

· Retain general usage of other Linux systems, such as. and:
