NIC Enumeration in XenServer Dell Edition
NIC enumeration (i.e., mapping of physical network interface to ethX device
name) in XenServer Dell Edition is based on the device position in the server.
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 slot
position and PCI bus/device/function information.
For example, if there are 2 LOM ports in a server and one dual port network
adapter in 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/function number)
The NIC enumeration and corresponding position in the server can be found
by logging in to XenServer local console shell and issuing the following
command:
# biosdevname -d
The output of the command must be similar to 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
