We use a bond (bond0) that consists of eth0 and eth1, to provide protection from a ethernet port/cable or switch failure.
We are using mode 4 (802.1ad/lacp), and our configuration looks like:
BONDING_OPTS="mode=4 miimon=100 lacp_rate=1"
We would like to be able to use the systemadmin interface to make changes to the interface, however if we do that, the configuration that is created by systemadmin drops the BONDING_OPTS line.
Is there any method that is available to ensure that is retained?
