I just checked TLV's. Below are the details:

OS :- CentOS 7.2
kernel 3.10.0-327.el7.x86_64
lldpad:- lldpad v0.9.46
dcbtool:- v0.9.46
ixgbe :- ixgbe-4.3.15

steps followed:- 

# modporbe ixgbe
# service lldpad start 
    Redirecting to /bin/systemctl start  lldpad.service

# service lldpad status
Redirecting to /bin/systemctl status  lldpad.service
● lldpad.service - Link Layer Discovery Protocol Agent Daemon.

Please help me in configuring traffic classes. I want to bringup DCB setup
in a back-to-back senario.
