Network requirements
Switch 7750s operate as the access devices of the operator's network, that is,
■
Switch C and Switch D in the network diagram.
S2000 series switches operate as the access devices of the user's network, that
■
is, Switch A and Switch B in the network diagram.
Switch C and Switch D connect to each other through the configured trunk
■
port of the switch, and are enabled with the BPDU Tunnel function. Thereby
transparent transmission is realized between the user's network and the
operator's network.
