Hi,
does Linux bonding driver support 802.3ad "port-priority" feature? For
example in Cisco devices one can assign a "lacp port-priority" to each
port on a device running LACP. The port priority is used to decide
which ports should be put in standby mode when a hardware limitation
or the "lacp max-bundle" command configuration prevents all compatible
ports from aggregating. Such feature is also supported for example on
Juniper gear. Based on "Linux Ethernet Bonding Driver HOWTO" bonding
driver does not seem to support this feature..
thanks,
Martin

No, it doesn't. All bonding slaves are set to port priority
(Actor_Port_Priority) of 255, and bonding has no equivalent to the
max-bundle option. The LAG selection logic described in 802.1AX 5.6.1
is not implemented, as bonding does not restrict the size of an
aggregation.
