Ok,
Not quite home free... I had setup with mode=4 miimon=100 and I get a:
nd0/bonding/Mode: Permission denied at /etc/rc.d/rc.network line 153
I have attached images of the error and code that it referrs to.
I had initially tried to setup mode 6, but not sure if that's supported...
Any help very much appreciated!
Regards
Alasdair
