2.1.e Implement and troubleshoot EtherChannel


next up was etherchannel… as i always do i set up sw1-3 as channel-group 1, sw2-4 as channel-group 1 (up-downs), the link beween sw1 and sw2 as channel-group 2 (sides), and each cross link as channel-group 3… as i mentioned before, i disabled the link between sw3-4 as per the instructions…

there was a requirement to perform dst-mac traffic distribution… nice that it’s global… src-mac is the default…

SW1(config)#port-ch ?
load-balance  Load Balancing method

SW1(config)#port-ch load-bal ?
dst-ip       Dst IP Addr
dst-mac      Dst Mac Addr
src-dst-ip   Src XOR Dst IP Addr
src-dst-mac  Src XOR Dst Mac Addr
src-ip       Src IP Addr
src-mac      Src Mac Addr

SW1(config)#port-ch load-bal dst-mac
