NIC Enumeration in Citrix
®
XenServer™
Dell™ Edition
NIC enumeration, i.e., mapping of the physical network interface to the ethX
device name in XenServer Dell Edition is based on the device position in the
system. The integrated LAN on Motherboard (LOM) ports are always
enumerated first in order of their physical marked position (GB1, GB2, etc.).
The add-in network cards are enumerated after the LOM ports in ascending
order of the slot position and the PCI bus, device or function information.
For example, if there are 2 LOM ports in a system and one dual port network
adapter in the PCI slot 4, the NIC enumeration is as follows:
• eth0 : LOM Port 1 (Gb1)
•
eth1 : LOM Port 2 (Gb2)
•
eth2 and eth3 : ports on adapter in slot 4 (arranged in ascending bus,
device or function number)
You can find the NIC enumeration and corresponding position in the system
by logging in to the XenServer local console shell and running the following
command:
# biosdevname -d
The output of the command must be similar to the one below:
BIOS device: eth0
Kernel name: eth0
Permanant MAC: 00:1E:4F:1F:77:67
Assigned MAC : 00:1E:4F:1F:77:67
Driver: bnx2
Driver version: 1.6.7b
Firmware version: 3.5.12 UMP 1.1.8
