5K Port-Channel Issue: command failed: port not compatible [DCE mode]

Answered Question
Feb 10th, 2011

I'm getting the following error when I try to configure

my uplinks on my 5K back to my 7K's.

     command failed: port not compatible [DCE mode]

I'm currently running NX-OS: n5000-uk9.5.0.2.N1.1.bin

Any ideas would be helpful.

interface port-channel10

  switchport mode trunk
  vpc 10
  switchport access vlan 5

  switchport trunk native vlan 2005

  switchport trunk allowed vlan 5,7

  speed 10000

interface Ethernet1/33
  switchport mode trunk
  switchport access vlan 5

  switchport trunk native vlan 2005

  switchport trunk allowed vlan 5,7

  spanning-tree port type network
  udld aggressive

channel-group 10 mode passive
command failed: port not compatible [DCE mode]

I have this problem too.
