N5K Interface unable to connect to port-channel - command failed: port not compatible [port native VLAN]

[REUBEN CHIN]

Not sure what this error message means.

This is my configuration in brief:

Model:  N5K5596 using Fabric Path

Software:  version 5.1(3)N2(1)

interface port-channel101

  description xxxxxxxxxxxx

  switchport

  switchport mode fabricpath

  lacp min-links 2

  switchport trunk native vlan 999

  fabricpath isis metric 5

interface Ethernet1/37

  description xxxxxxxxxxxxx

  switchport

  switchport mode fabricpath

  channel-group 101 mode active ******  UNABLE TO APPLY THIS LINE  ******

command failed: port not compatible [port native VLAN]

===========

I have configured the Native VLAN999

I have removed the Po101 and re-added it in hopes it would work, it did not work.

The features currently applied are:

feature-set fabricpath

feature telnet

no feature http-server

feature tacacs+

feature private-vlan

feature udld

feature interface-vlan

feature lacp

feature dhcp

feature vpc

feature lldp

Hoping someone has further answers, I'll cont. looking through the whitepapers for any possible answers.

Removed the configuration for Po101

Configured all applicable ports which will participate with Po101

Re-Configured Po101 with the original config.

interface port-channel101

  description xxxxxxxxxxxx

  switchport

  switchport mode fabricpath

  lacp min-links 2

  switchport trunk native vlan 999

  fabricpath isis metric 5

Everything is working.

I always thought you could configure additional ports without modifying the actual port channel.  That is not the case.  The Port Channel must be configured last.  Adding additional interfaces after the Po has been created didn't work.

you can't just add channel group command to the interface hoping that it will assign logical port-channel settings to physical interface. it won't work when new member is added.

make sure the port-channel type: l2/l3 and mode access/trunk

L2: add switchport cmd to the member interface.

L3: add no switchport cmd to the member interface.

Order:

1. configure the port-channel.

2. apply similar configuration of port channel to the member ports.

3. add channel-group mode xx active to the member ports.

this must work.

Thanks,
