Ran through the labs in the BCMSN portfolio tonight concerning etherchannels. Fun little lab really. Simple, yet to the point. Went over the various modes:
channel-group [#} mode [active (LaCP), auto (PaGP), desirable (PaGP), passive (LaCP), on]
Actually did not have enough crossovers to do the entire lab with, but made my own little scenario up and used bits and pieces from theirs. Did some layer 2 etherchannels, along with a L3 channel using ip addresses on which to verify connectivity. Used the show commands:
show ether summary
sh ether [#]
sho ether load-balance
And configured different load balancing mechanims with the command
(config)port-channel load-balance [type]
Lastly, learned a cool interface command that allows you to statically define the protocol to use (either LaCP, or PaCP)
(config-if)channel-protocol [protocol]
