It's the cost of the port-channel interface. The bandwidth of the
port-channel is based on the aggregate of its active member interfaces.

"ip dhcp-server" is really just a subset of the ip helper-address
command. The difference is that it will only forward dhcp requests as
opposed to other UDP ports like TFTP, DNS, and NTP.
