Hey ITPro.TV, ran into a test question that is twisting my head a little. Can you clarify? The answer to the question indicated by the practice exam is "A", but if you look at the config of a switch this doesn't make a lot of sense. If you set a channel-group to mode "auto", doesn't that mean it is going to do PAgP only? The only way to get JUST Etherchannel is to use "mode on" at each end. Right?
active Enable LACP unconditionally
auto Enable PAgP only if a PAgP device is detected
desirable Enable PAgP unconditionally
on Enable Etherchannel only
passive Enable LACP only if a LACP device is detected
You have executed the following commands on a switch:
Switch64(config)# interface range gigabitethernet2/0/1 -2
Switch64(config-if-range)# switchport mode access
Switch64(config-if-range)# switchport access vlan 10
Switch64(config-if-range)# channel-group 5 mode auto
In which of the following situations will Switch64 create an Etherchannel?
A. If the other switch is set for desirable mode
B. If the other switch is set for auto mode
C. If the other switch is set for on mode
D. If the other switch is set for passive mode
