This error indicates an attempt to set an invalid value for the ''[[:cfg:mac]]'' address of a network interface.

Things to try:

  * Check that the address you are attempt to set is correct.

  * Check the type of the network interface using the ''[[:cmd:ifstat]]'' command.  Some network interfaces will autodetect the type of network that they are attached to (e.g. Ethernet or Infiniband), and will refuse to accept a ''[[:cfg:mac]]'' address for the wrong type of network.
