Keywords : How to combine multiple links into one BIG link, etherchannel, bundle multiple physical links into a single logical link, cisco pagp vs lacp, cisco etherchannel configuration, combine 2 links into 1 link, bundle 2 physics, bundle 2 physical links into a link.

I use a computer that does a continuous ping to observe the changes that occur during the configuration, as well as the problems that occur.

We have two physical links between switches.
