Changing NIC MAC addresses

TJ_16 — Fri, 30 Jul 2004 09:48:41 GMT

It was suggested to me to change some NIC addresses to the local MAC address to clear some VCS issues. Any one out there know of a way to change the MAC address to the local MAC?

Dual port NIC card is:
Intel Corp. 82546EB Gigabit Ethernet Controller

If you wish to define virtual Mac address then add a line:
MACADDR=
to /etc/sysconfig/network-scripts/ifcfg-ethx

The actual MAC address on the card can't be changed. Every once in a while the maker ships a card with a bad mac addy or it loses it. At that point the card has to be replaced. If its built on the the motherboard, it has to be replaced under warranty or replaced with an add in NIC.

For change mac address you can type:

# ifconfig eth0 hw ether deadbeef0001

this command must be run when the network card is NOT active!

You might try MAC Changer for linux also. May or may not work with your setup.
