Here's an example show command from a Dell Support Page that illustrates Ports spanning multiple switches that are active in a Port Channel:
Example
Channel Ports Hashing-mode
------- --------------------------------------- ------------
ch1 Active: 1/e1, 2/e2 1
ch2 Active: 2/e2, 2/e7 Inactive: 3/e1 2
ch3 Active: 3/e3, 3/e8 3
ch4 No Configured Ports 5
ch5 No Configured Ports 6
ch6 No Configured Ports 4
ch7 No Configured Ports 3
ch8 No Configured Ports 3
I still need to get some Demo switches. You would think that Dell would be advertising this feature way more since Cisco is the only other vendor that does this, that I know of.
