Connecting two Nexus 5020 with 10G ISL link

Hi Experts,

I am trying to connect two nexus 5020 with a 10G ISL link.

Per my understanding, with new release 5.0.3 N2(2a) ISL link between two nexus switch is supported.

Following is my config

c5020-1(config)# show running-config int vfc 32

!Command: show running-config interface vfc32

!Time: Fri Dec  2 01:14:38 2011

version 5.0(3)N2(2a)

interface vfc32

  bind interface Ethernet1/32

  switchport mode E

  switchport trunk allowed vsan 3040

  no shutdown


c5020-1(config)# sho running-config int eth1/32

!Command: show running-config interface Ethernet1/32

!Time: Fri Dec  2 01:16:15 2011

version 5.0(3)N2(2a)

interface Ethernet1/32

  switchport mode trunk

  spanning-tree port type edge trunk


I have similar config on the other switch. But for some reason the link does not come up. vfc port keep "initializing" and Eth port stays isolated.

c5020-1(config)# sh int vfc32

vfc32 is trunking (Not all VSANs UP on the trunk)

    Bound interface is Ethernet1/32

    Hardware is Virtual Fibre Channel

    Port WWN is 20:1f:00:0d:ec:ca:04:bf

    Admin port mode is E, trunk mode is on

    snmp link state traps are enabled

    Port mode is TE

    Port vsan is 3040

    Trunk vsans (admin allowed and active) (3040)

    Trunk vsans (up)                       ()

    Trunk vsans (isolated)                 ()

    Trunk vsans (initializing)             (3040)

    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 Dec  2 01:17:28 2011


c5020-1(config)# sh int eth1/32 fcoe

Ethernet1/32 is FCoE Isolated


If any expert throw some light to make me understand things better will be helpful.


Connecting two Nexus 5020 with 10G ISL link

i have not connected two Nexus before but looking at your eth 1/32 interfaces you think it needs to be "

switchport trunk allowed vlan" your "FCOE" VLAN ?
