Network requirementsz S7500 series switches operate as the access devices of the operator’s network,that is, Switch C and Switch D in the network diagram.z S3100 series switches operate as the access devices of the user’s network, that is,Switch A and Switch B in the network diagram.z Switch C and Switch D connect to each other through the configured trunk port ofthe switch, and are enabled with the VLAN-VPN function. Thereby transparenttransmission is realized between the user’s network and the operator’s network.
