  1. Hello Rene,

    port-channel load-balance {dst-ip | dst-mac | src-dst-ip | src-dst-mac | src-ip | src-mac}

    could you please explain what is the function of {dst-ip | dst-mac | src-dst-ip | src-dst-mac | src-ip | src-mac} and how load is converting in each link based on load balancing ?

  2. Hi Hans,

    The default is src mac based load balancing.

    From SW1’s perspective this is a great choice as each computer has a different MAC address. Traffic from the computers will be load balanced when it is sent from SW1 to SW2.

    From SW2 to SW1, it’s another story. The MAC address of the router remains the same so using src mac based load balancing is not a good idea. All traffic will be sent using the same physical interface. It’s better to change it to dst mac address load balancing since the destination MAC address will be one of the four computers.

  3. I understand about the trunk. My understanding was a bit flawed. I was thinking we were combining a path and then seperating it again.

    Also, if we are on a network built entirely with cisco gear, is there a better choice between LACP and PAgP? If so, why and when is one better?

    Thanks in advance!

  4. I dont think there is a difference between the two in regards to pros and cons. The only advantage I could see is that PAgP might be “quicker” to configure since the default protocol used for etherchannel is PAgP on Cisco equipment. After some googling there was no clear advantage I seen. One advantage of both LACP and PAgP is they help prevent loops manual etherchannel configurations do not allow for this. I hope this was helpful!

  5. Thank you very much Laz for this intuitive explanation
