>From your switch, run the following tests:


core1.drt.hi-media#test etherchannel load-balance interface port-channel
2 ip 1.2.3.4 5.6.7.8
Would select Gi1/1/1 of Po2

core1.drt.hi-media#test etherchannel load-balance interface port-channel
2 ip 1.2.3.4 5.6.7.9
Would select Gi2/1/1 of Po2

core1.drt.hi-media#test etherchannel load-balance interface port-channel
2 ip 1.2.3.4 5.6.7.10
Would select Gi2/1/1 of Po2



Of course, you'll want to adjust with your own servers and PC IP addresses.
