Nexus 5k vfc won't come up


I have a n5k already configured with a fiber san and esx host running cna's.  I'm trying to add another and I just can't get the vfc to come up.  I've posted my config and a couple sho's that I've found through other discussions....

vsan 18 is already up with 3 hosts, I'm trying to add a 4th.  The port in question is eth 1/15, vfc 15.  Status oper is down

    Port WWN is 20:0e:00:0d:ec:ef:38:ff

    Admin port mode is F, trunk mode is on

    snmp link state traps are enabled

    Port vsan is 18

Any ideas?

Re: Nexus 5k vfc won't come up

Configuration wise, I do not see anything standing out. A vFC will not come up until the host associated with it sends out a FLOGI frame. Make sure your CNA has the appropriate FCOE drivers and is initiating FLOGI. Also  make sure the CNA supports the media type you are using.

Re: Nexus 5k vfc won't come up

Make sure your vlan is in the vlan database and the vsan is in the vsan database.

If you have a qlogic qle 8152, then you need a twinax cable.
