I have the core stack using 7 3750 switches with multiple port channels setup, and we have remote locations with 3560 switches all using port channels. I need the commands to see all port channels setup on the 3750 along with the 3560 switches. I need some help or step-by-step information on how to setup a new port channel for another 3560 switch I'm adding to the network.
P/S is there a document for port-channel configuration also.
For full detail use "show etherchannel detail". For a less busy output use "show ether summ" . For a new channel between cisco devices do the following as an example.
int port-channel 25
For the ports in the channel.
interface range g1/0/X , g1/0/X
channel-group 25 mode desirable non-silent
After this then do a "no shut on the port channel interface on each end to bring up the channel.
