>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.
