Re: OT: EtherChannel Hash

It will load balance based on the MAC change for example:

10 pc------|switch|----4 ports in port-channel1-----|switch2|

PC1- po1/port1
PC2- po1/port2
PC3 -po1/port3
PC4 -po1/port4
pc5-po1/port5
pc6-po1/port6

and so on.......
it dosen't mater what MAC and what bits of MAC or IP address is changing.
