No FCoE Login / Nexus 5K

rebert · ‎11-25-2011

Hi all

We have a problem with FcoE connection from the HP7000 Encosure with Passtru-Moduls (Emulex OneConnect CNA) connected to a Nexus 5548.

VFC interface status is still initializing

tpixxc# sh int vfc 1

vfc1 is trunking (Not all VSANs UP on the trunk)

Bound interface is Ethernet102/1/15

Port description is tpixxc-hvcm33-ENC59/Bay15, vfc1

Hardware is Virtual Fibre Channel

Port WWN is 20:00:00:05:73:ee:ae:3f

Admin port mode is F, trunk mode is on

snmp link state traps are enabled

Port mode is TF

Port vsan is 1300

Trunk vsans (admin allowed and active) (1,1000,1300)

Trunk vsans (up) ()

Trunk vsans (isolated) ()

Trunk vsans (initializing) (1,1000,1300)

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

0 frames input, 0 bytes

0 discards, 0 errors

0 frames output, 0 bytes

0 discards, 0 errors

last clearing of "show interface" counters never

Interface last changed at Fri Nov 25 13:17:30 2011

It seems that the FIP Prozess not work proper.

QoS should be ok.

Here the FCoE configuration:

vlan 1402

fcoe vsan 1300

name liehfc-Fabric_D_Accesszone

!

vsan database

vsan 1000 name "Infrastruktur"

vsan 1300 name "Accesszone"

!

interface vfc1

bind interface Ethernet101/1/31

switchport description tpixyc-hvcm33-ENC59/Bay15, vfc1

no shutdown

!

vsan database

vsan 1300 interface vfc1

vsan 1000 interface san-port-channel 53

!

interface Ethernet102/1/15

description tpixxc-hvcm33-ENC59/Bay15, vfc1

no cdp enable

switchport mode trunk

switchport trunk native vlan 2444

switchport trunk allowed vlan 1402,2444,3790

spanning-tree port type edge trunk

no snmp trap link-status

service-policy type qos input PM-QOS-EDGE

!

any idea ?

Thanks for help

Are there other devices already operating via FCoE on the same 5K?

What is in your service-policy on the interface, and have you tried it without the policy?

(You may also want to bind the VFC to the physical interface in your config.)

Hi Rebert,

what is the firmware that you are using? I am seeing similar issue in my environment with version

5.0(3)N2(2)

Thanks,

Raj

Do you have any servers which are not in HPC7000 which are FLOGIed in fine? Have you made sure that server in HP chassis is sending Fabric Logins? Also, since there would be muliple logins to one vFC, you will need "feature npiv" enabled on the N5k.
