Hello,
I use VN2VN mode and tried to create the following topology:
eth2.569 (ixgbe) tap0.569------ fcoe target
| |
--------------- virbr1---------------
I attached my script including output and the syslog at the end.
Why does the call dcbtool fail with this message: Device not found, link
down or DCB not enabled???
-------------------------
ifconfig virbr1 up
ifconfig tap0.569 up
ifconfig eth2.569 up
sleep 1
iptables -A FORWARD -i tap0.569 -o eth2.569 -j ACCEPT
iptables -A FORWARD -o tap0.569 -i eth2.569 -j ACCEPT
sleep 1
service fcoe restart
echo tap0.569 > /sys/module/libfcoe/parameters/create_vn2vn
echo tap0.569 > /sys/module/libfcoe/parameters/enable
sleep 1
lldpad -d
sleep 1
dcbtool sc dcbx v:cee
sleep 1
ifconfig tap0 up
sleep 1
dcbtool sc tap0 dcb on
sleep 1
dcbtool sc tap0 pfc a:1 w:0 e:1 pfcup:00010000
sleep 1
dcbtool sc tap0 app:fcoe a:1 w:1 e:1
sleep 1
service lldpad restart
sleep 1
-------------------------
Here the complete output:
