I have 4 units of Cisco 3750, 12 ports stacked switches.
I have port channel configured on the stacked switches.
SW1, Stacked 1 G1/0/1 connected to G1/0/1, SW2, Stacked 1
SW1, Stacked 1 G2/0/1 connected to G2/0/1, SW2, Stacked 1
Then, I will configure a port channel, say Po1
I knew that for x-stack etherchannel, I need to use LACP instead of PAGP.
How do I make sure that the LACP protocol was used?
Does it means that if I used " channel-group 1 mode active" command, then, the cisco 3750 will automatically using LACP?
Or, do I need to use the "channel-protocol lacp" command?
