I run active-backup mode and it works splendid.
However, is it possible to have a preferred channel?
I have one gigabit fiber uplink and one 100mbit ethernet, and it would be nice if the gigabit would be used as much as possible (since the 100mbit is fully utilized)
Is there any other mode that would accomplish my goals of reliability and speed with one 1000mbit and one 100mbit?
A string (eth0, eth2, etc) specifying which slave is the
primary device. The specified device will always be the
active slave while it is available. Only when the primary is
off-line will alternate devices be used. This is useful when
one slave is preferred over another, e.g., when one slave has
higher throughput than another.
The primary option is only valid for active-backup mode.
