Nexus 7010 and NetApp Etherchannel Issue

I  currently have an etherchannel configured between my Nexus and a NetApp device. I have two 4-port etherchannels that are set for LACP (mode active) that are working and 1 2-port configured exactly the same that won't work.            

12    Po12(SU)    Eth      LACP      Eth1/17(s)   Eth1/18(P)

I turned on LACP error debugging and the error I get when I shut the Eth 1/17 interface and bring it back up is:

2012 Jun 15 14:09:46.731141 lacp: lacp_proto_suspend_secondary_ports(2049): Ethernet1/20(0x1a013000): Got port with non matching lag selection

2012 Jun 15 14:09:46.731177 lacp: lacp_proto_suspend_secondary_ports(2050): Port LAG=[(1, 2-a0-98-1c-a7-3e, 1, 0, 4), (8000, 40-55-39-25-75-41, c, 8000, 114)]

2012 Jun 15 14:09:46.731200 lacp: lacp_proto_suspend_secondary_ports(2052): Port channel LAG=[(1, 2-a0-98-1c-c7-86, 1, 0, 0), (8000, 40-55-39-25-75-41, c, 0, 0)]

The configuration of the ports:

interface Ethernet1/17

  description NetApp NAS


  switchport access vlan 2

  storm-control broadcast level 1

  storm-control multicast level 1

  channel-group 12 mode active

  no shutdown

interface port-channel12

  description TSG-NAS5 Etherchannel


  switchport access vlan 2

  spanning-tree port type edge

  storm-control broadcast level 1

  storm-control multicast level 1

Any ideas of why lacp is having this issue?

Missing spanning tree port type edge on the port itself.

Nexus 7010 and NetApp Etherchannel Issue

Looks like that got rid of the lacp error messages. I turned on etherchannel debugging and now I get this when shut/no shut on the port.

Same problem with same errors

Same problem with same errors but I just fixed it.  I had 2 Po's with 2 int's each.

Po55     Po56

e1/17     e1/19

e1/18     e1/20

One int in each Po was in suspnd.  I deleted Po56, defaulted both int's (19 & 20), added ints 19 & 20 to channel-group 55. This time when doing a "sho port-c sum" Po55 showed int's 17 and 19 up and working. Int's 18 and 20 were in suspnd.  I configured Po56 with int's 18 and 20 and it came up. 

Basically, it looks like the cables may have been mixed up.
