Etherchannel Hash calculation

[network_geek1979]

Hi,

I am trying to get into some depths of how a etherchannel on Cisco switch works.

My question is how is the RBH value calculated?

I issue this command on a Cisco C6807 switch and have the below output.

sw-core-ind-pun4-b1f6s1#test etherchannel load-balance interface port-channel 90 ip 192.168.1.1 192.168.1.2
Computed RBH: 0x3
Would select Te2/5 of Po90

How did the calculation work?

Thanks,

Neel
