DHCP through L3 Etherchannel

Hi Laz,
Thanks for the info. I am trying to determine the path the BPDU’s take, from the root bridge, and from the root ports. Is there a way to determine their path? I reassigned the ip’s to the switches, putting all in the same subnet, 192.168.10.1, 192.168.10.2, etc, and I can ping between the vlans on the different switches.
The command I was referring to is, if there is a command that shows all the mac addresses of the switch, all at once.
