I'm trying to configure DCB in back-to-back scenario.
System 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.
Loaded: loaded (/usr/lib/systemd/system/lldpad.service; disabled; vendor
preset: disabled)

# dcbtool gc p3p2 dcb
Command: Get Config
Feature: DCB State
Port: p3p2
Status: Successful
DCB State: off
# dcbtool sc p3p2 dcb on
Command: Set Config
Feature: DCB State
Port: p3p2
Status: Successful
# dcbtool gc p3p2 dcb
Command: Get Config
Feature: DCB State
Port: p3p2
Status: Successful
DCB State: on
Similar configuration on another system.
But as soon as I do "ifconfig p3p2 up and check dcb
# dcbtool gc p3p2 dcb
Command: Get Config
Feature: DCB State
Port: p3p2
Status: Successful
DCB State: off
Initially suspecting issue with lldpad daemon/ixgbe driver. I replaced them
(downloaded from repo) with latest packages.
Same behaviour observed.
- Tried disabling other dcb features like fcoe. Same issue.
- Disabled selinux etc
Can any 1 help me regarding this.

I'm adding e1000-devel as that is the mailing list for the ixgbe maintainers.
You might want to go through and also check the number of TCs and how
you have them mapped to your priority groups. It is possible that one
end or the other may only have 1 TC configured and if I am not
mistaken that is interpreted as having DCB disabled by the hardware.
Hope that helps.

hmm those are older version of the tool but that shouldn't necessarily
be an issue.
The output from the following would help, (note if the peer is not
configured correctly as well DCB will be disabled)
#dcbtool go p3p2 pg
#dcbtool go p3p2 pfc
#lldptool -t -i p3p2
#lldptool -t -i p3p2 -n
The first two dcbtool commands give the dcb status and the last two
lldptool commands print the sent/received lldp TLVs.
