channel-group NUMBER (Must match at each end) mode on – No protocol used?
This will enable Etherchannel only with no specified protocol
Logical interfaces always appear at the top of a configuration
Use the interface range command to avoid having to do each port manually, be aware that if set 1 side with a delay, this can err disable ports locally as the other side has no configuration
show etherchannel ? (several options)
summary and detail are helpful commands
detail shows you how long a physical port has been in the bundle
show pagp/lacp neighbor – details neighbours in Etherchannel bundles
show etherchannel brief
Look out for vlan masking on physical interfaces, will impact the logical interface.
Ports in an Etherchannel can be source SPAN ports but NOT destination SPAN ports.
