Port channel LACP to self issue

Hi Samim,

Thanks for reaching out.

Please refer to the below TOI for LACP on Loopback interfaces:

https://eos.arista.com/eos-4-18-0f/lacp-on-loopback-interfaces/

a)As per the TOI,

LACP on Loopback Interfaces is disabled by default, and must be explicitly enabled on the loopback port-channel.

LACP on Loopback Interfaces can be enabled using:

Arista(config-if-Po1)#port-channel lacp loopback

b)Also as mentioned in the TOI, if we are configuring 1st scenario then that is not supported.(As far as I understand this is the one which is being configured in your network environment).

However 2nd scenario works fine.

Thanks,

Bhavana.

Thanks for info, but my question is not about to enable the Port-channel on loop back interface. My question is to connect 2x physical interfaces with 2x port-channels on the same Switch.

Hi Samim,

I think, to understand your query better, it would be helpful to have your configuration and a topology diagram you want to achieve.

Could you please share the topology and the configuration you are implementing?

Hello Samim,

The below command shared by Bhavana should allow connecting two ethernet interfaces on the same device via a port-channel (and not loopback - LoX interfaces):

Arista(config-if-Po1)#port-channel lacp loopback

Please note that this configuration has to be entered in the port-channel configuration mode.

This command is supported since EOS-4.18.0F. However, in case you are running an older version of EOS on the device or if this issue is observed only with a break-out cable, you could configure static port-channels.

Thanks,

Sneha
