■ LAG port changes are not revertive. As a result, if a port in the LAG goes down,
traffic flows are remapped based on the hashing algorithm (see “Port Assignment
in the LAG” on page 226). When the port comes back up, traffic does not revert
back to the port that was originally supporting the traffic. Only new traffic flows
can be mapped onto this port.
LAG Numbering
The Oracle Fabric Interconnect uses a slot and port numbering convention to
identify the physical port that is the termination point for a vNIC. However, when
you use a LAG, the standard slot and port numbering convention is not used.
Instead, when you specify a LAG, you use a slot and a LAG ID from 1 to 5 separated
by a period (.). For example, to specify LAG 4 on slot 5, you would identify that
LAG as 5.4. Be aware that LAGs require a period (not a slash) to differentiate them
from a standard slot and port termination.
LAGs, like most objects in the Oracle Fabric Interconnect, have “Naming
Conventions” on page 8.
LAG Commands
LAGs are supported on the Oracle Fabric Interconnect through the add lag, set
lag, show lag, and remove lag commands. Be aware that the LAG must also be
configured on the peer Ethernet device.
