[AusNOG] DCB in non-converged networks

[Luke Iggleden]

Hi Andres,

Unless you are running other services on the switch it's not useful.

Typically these are the only useful changes:

Jumbo Frames (YMMV), depends on vendor.

Flow Control on (so hosts can issue back off - hopefully without 
dropping frames)

Depending on the switch, buffer tuning.

Don't use control plane things, like MLAG, Stacking, STP, etc etc. Flat 
fabric.


Cheers,

Luke Iggleden
