active-backup or 1
Active-backup policy: Only one slave in the bond is active. A different slave becomes active if, and only if, the active slave fails. The bond's MAC address is externally visible on only one port (network adapter) to avoid confusing the switch.
primary
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.
Działa! Dziękuję.
Gdzie doczytałeś, że to ma być w tym pliku? Co to za plik?
PS. Gdy zrobimy do tego interfejsu most, to tracimy jeden ping podczas przełączania interfejsów. Gdy jest tylko bonding, to zero strat (to tak tylko dla zainteresowanych).
