Configure network interworking of network elements (NEs) to ensure proper data transmission.
Management packets between an AC and APs are transmitted only on the network between them. To ensure that the AC and APs exchange management packets properly, configure correct VLANs or routes.
Service packets are transmitted between STAs and the upper-layer network. Configure service packet exchange to ensure proper transmission of service packets.
Service packets here also include ESL update packets. Ensure that ESLs can communicate with the ESL management system.
The APs and STAs must obtain IP addresses from a DHCP server; therefore, you need to configure the APs and STAs to communicate with the DHCP server.
Configure interworking of ESL cards, APs, and the ESL management system, so that the ESL management system can connect to and exchange packets with ESL cards inserted into the APs.
You can only configure Layer 2 interworking between the ESL cards and ESL management system because the ESL management system can discover ESL cards only by sending Layer 2 network broadcast packets. For details on how to configure interworking between ESL cards and APs, see Configuring Interworking Between ESL Cards and APs. Configure interworking between the ESL management system and APs based on the actual network conditions.
The ERP system is used to manage and update commodity prices, and synchronize updated information to the ESL management system. You need to configure interworking between the ESL management system and ERP system.
