I'm try to bond a few interfaces together with the hopes of getting
increased throughput, and I'm using a cisco Catalyst 2900 as the switch.
I've tried using mode 0, 5, and 6 with nothing special on the switch,
and mode 4 with some ports "trunked" together (I have a feeling that
the
"trunking" that the 2900 does is not 802.3ad, as it disabled the ports
it saw as redundant), yet xfer speeds always cap out at about 10MB/s.
Has any body accomplished bonding with increased throughput as the goal,
with or without (without might be preferable) doing something special on the
switch (preferably the
afore-mentioned Catalyst 2900, as that is what I have to work with as a
non-sactioned side-project ;)?
