Hello,
I have a Nex 5548 version 5.0(3)N1(1b)
at this time release to configure FCoE was simply the steps of mapping VLAN to VANS, creating vfc and adding the vfc to the good vsan..
now I'm stuck.
I've my interface Eth in a PO. I bound the vfc to this po. and when the server boot up, I simply have the vfs stuck in "vfc x is trunking".
sho inter vfc 1258
vfc1258 is trunking
Bound interface is port-channel1258
Port description is "esx58 FAB2"
Hardware is Virtual Fibre Channel
Port WWN is 24:e9:00:05:73:cd:70:ff
Admin port mode is F, trunk mode is on
snmp link state traps are enabled
Port mode is TF
Port vsan is 2
Trunk vsans (admin allowed and active) (2)
Trunk vsans (up) ()
Trunk vsans (isolated) ()
Trunk vsans (initializing) (2)

a cannot turn off the trunk mode of the vfc.
let me show you the vfc conf:
interface vfc1258
bind interface port-channel1258
switchport trunk allowed vsan 2
switchport description "esx58 FAB2"
no shutdown
honestly when i run these conf against a Nex 5010 in rev 4.2 it was working straitforward. how can I set this vfc to F mode only?
hope you will help me.
thanks in advance.

Hi eric,
this should be as simple as
# conf term
(config)# interface vfc 1258
(config-if)# no switchport trunk allowed vsan all
(config-if)# end
#

Nice try, but I got this on both host interfaces:
vfc1258 is down (Isolation due to no common vsans with peer on trunk)
Bound interface is port-channel1258
Port description is "ditex-esx58 FAB2"
Hardware is Virtual Fibre Channel
Port WWN is 24:e9:00:05:73:cd:70:ff
Admin port mode is F, trunk mode is on
snmp link state traps are enabled
Port vsan is 2
1 minute input rate 0 bits/sec, 0 bytes/sec, 0 frames/sec
1 minute output rate 0 bits/sec, 0 bytes/sec, 0 frames/sec

Hi Eric
Did you find a solution on this ? I'm having the exact same issue and I have tried just about anything.
Tnx

Sorry about the delay.
this was related to the fact the Cisco doesn't enable by default the QOS for FCoE on their nes Nexus 55xx switches.
enabling the proper QOS for FCoE can be found on the following page:
once done you vfc will come up.

Hi,
I have the same problem, when running 5.2(1)N1(1). The adapter is an LP21002-C, which is a Generation 2 CNA configured as a "Fabric point to point" interface on the Emulex side.
We've tried setting the QoS as explained in the parent post, to no avail.
When connected to a release 4, things work. When connected to release 5:
# sho int vfc4
vfc4 is down (Initializing)
interface port-channel4
switchport mode trunk
switchport trunk allowed vlan 10
speed 10000
vpc 4
interface vfc4
bind interface Ethernet1/4
no switchport trunk allowed vsan all
no shutdown
interface Ethernet1/4
switchport mode trunk
switchport trunk allowed vlan 10
spanning-tree port type edge
channel-group 4
