Best practice for a trunk Etherchannel between two Cisco 9300 stack.

[billy_vaughn]

I'm looking for some best practices for setting up a trunked Etherchannel between two 9300 switch stacks. We have had issues with Etherchannel setup since moving to the 9300 platform. I've always configured a port channel > then setup my interfaces with the following and they work until we got 9300's. I'm not sure whether the non negotiate commands are a problem or not but this setup below is currently working but we are trying to add another new stack and the interfaces go into err disable state as soon as you do a shut/no shut. Same config as below on the new stack but with a new 

Switch 1

interface Port-channel1
switchport mode trunk
switchport nonegotiate

interface GigabitEthernet1/1/1
description Uplink to core
switchport mode trunk
switchport nonegotiate
channel-group 1 mode on
!
interface GigabitEthernet1/1/2
description Uplink to core
switchport mode trunk
switchport nonegotiate
channel-group 1 mode on

Switch 2

interface Port-channel23
description ESX_DEV_SWITCH Trunk
switchport mode trunk

interface GigabitEthernet1/0/5
description ESX Dev Sw1 Uplink
switchport mode trunk
channel-group 23 mode on
!
interface GigabitEthernet1/0/6
description ESX Dev Sw3 Uplink
switchport mode trunk
channel-group 23 mode on

Good to hear.

Make sure you mark this as solved so the community can see how it was fixed. You can either use my first or second response about turning off the no negotiate command or even yours saying how you got it working. 

Thank you
