Using the Interface Range mode
If you are applying the same configuration elements to a number of LAGs (also called bulk configuration),
you can replicate the steps shown in the examples above for all of those LAGs from the Interface Range
mode. The System Configuration chapter in the SFTOS Command Reference provides details on the
command syntax used for the
interface range command to define the range and access the mode.
The command families available from the Port Channel Range prompt within that mode are displayed here.

Link Aggregation Control Protocol (LACP)
The Link Aggregation Control Protocol (LACP) provides a standardized means of exchanging information
between two systems (also called partner systems) and dynamically establishing LAGs between the two
partner systems.
LACP allows the exchange of messages on a link to allow their Link Aggregation Control instances to
reach agreement on the identity of the LAG to which the link belongs, move the link to that LAG, and
enable the transmission and reception functions in an orderly manner.
SFTOS configures dynamic LAGs by default, using LACP. The SFTOS implementation of LACP is based
on the standards specified in the IEEE 802.3: “Carrier sense multiple access with collision detection
(CSMA/CD) access method and physical layer specifications.”
Note: You can approximate LAG bulk configuration when you assign a group of ports to a LAG
with one channel-member command (Interface Port Channel Config mode). For example,
channel-member 1/0/10-1/0/14.
