10. Lantech Pioneering Industrial and IP Networks TM Smart DHCP: Advantages and Benefits Most of switch products are not built in DHCP Option 82 server but relay agent function where network need another DHCP Option 82 server which might be a difficulty in harsh network like vehicle, train or track side

11. Lantech Pioneering Industrial and IP Networks TM Most switches are able to adapt QoS function but the device must be able to acknoledge QoS packet or by port based QoS. However, through VLAN, the QoS setting can be simple. The “Advanced QoS” is the best and most convenience solution for traffic-management no matter the devices supporting QoS or not. Users can do planning at application level and make network performance more predictable and bandwidth utilization more effective. For example, IP cam and VOIP phone are in the same network but need to prioritize VOIP packet in VLAN1, with Advanced QoS, the VOIP packet will be sent in prior to video multicast packet where user don’t need to worry whether VOIP device is able to read QoS packet.
