Hello,

Hi Jeorgkost,

 

I just already enabled both interfaces of connected MLX and it went up.

Here is my first configuration.

 

Can I verify if it Is successful LAG? how can I see the connected peer?

In VDX I can see by show LLDP neighbor, and in Summit by show fdb

Hello Sazon,

 

I think you are looking for

show lacp lag_id 10

If you also want to run LLDP, you need to enable it first:

(config)#lldp ?
