Error after on-boarding when attaching to port-channel

[DevOps_RC]

I created a new port-channel and tried to attach two interfaces to it, however I received the error message below:

Command rejected: conflicts with IPv6 Snooping (FHS)

In order to attach the interfaces to the port-channel I had to remove the following line from each interface:

no device-tracking attach-policy MERAKI_POLICY

This is just information in case anyone else comes across the issue, and while it did allow me to attach the interfaces to the port-channel, it wouldn't allow me to add the device-tracking command back into each of the interfaces after they were linked to the port-channel.

Is It a Maraki switch or catalyst switch?

[alemabrahao]

Have you tried to run the command default on interfaces?

[DevOps_RC]

I haven't tested that, but I can try that out tomorrow on an unused port. 

[DevOps_RC]

The switches are Catalyst 9300s.

Thanks @DevOps_RC for the workaround.

I have the same problem here with a 9300 running 17.04.

Ports that were already in a port channel before the on-boarding seems fine but i can't add new ports.

Do you have an update on this issue ?

@jorisjean No update on this sorry.
