Re: Configure traffic class to bringup DCB in back-to-back setup

So at the moment it appears to be configured to use 802.1QAZ spec which
superseded the older spec even though lldpad supports both. Note the
tool itself really requires some spec knowledge to use correctly. The
spec to read is 802.1Q.

To configure it back-to-back (typical scenario is connected to a DCB
enabled switch where your administrator would setup the switch and this
would autoneg just fine) the servers need to be setup manually.

Perhaps reading if you haven't already the man page for lldptool and
lldptool-ets, lldptool-pfc would help. From the ets man page this
should kick things off,

#lldptool -T -i eth2 -V ETS-CFG \
          tsa=0:ets,1:ets,2:ets,3:ets,4:ets,5:ets,6:ets,7:ets \
          up2tc=0:0,1:1,2:2,3:3,4:4,5:5,6:6,7:7 \
          tcbw=12,12,12,12,13,13,13,13

#lldptool -T -i eth2 -V ETS-REC \
           tsa=0:ets,1:ets,2:ets,3:ets,4:ets,5:ets,6:ets,7:ets \
           up2tc=0:0,1:1,2:2,3:3,4:4,5:5,6:6,7:7 \
           tcbw=12,12,12,12,13,13,13,13

Hi John,
 
I have gone through  lldptool and lldptool-ets man pages. My query is how to
categorize traffic. 

My aim is to allocate bandwidth to different type of traffic(may be based on
port or protocol) using DCB( ETS/PFC) functionality.

Thanks
