MANAGEMENT SERVER AND MANAGEMENT METHOD THEREOF FOR MANAGING CLOUD APPLIANCES IN VIRTUAL LOCAL AREA NETWORKS

摘要

A management server and a management method thereof are provided. The management server is connected to a switch on a trunk port. The switch is connected to a plurality of cloud appliances in different virtual local area networks (VLANs). The management severs operates a management system and a translation system for managing cloud appliances. The translation system is operated to modify the receiving data packet by converting the source MAC address or the source IP address and removing the VLAN tag, and to modify the transmitting data packet by converting the destination MAC address or the destination IP address and adding a VLAN tag.

1. A management server for managing cloud appliances in virtual local area networks (VLANs), comprising:
a network interface, being connected to a switch on a trunk port; a storage, being configured to store a translation mapping table; and a processing unit, being electrically connected to the network interface and the storage and configured to receive a first external data packet with a none source internet protocol (IP) address, an external source media access control (MAC) address and a VLAN tag from the switch via the network interface and operate:
a management system; anda translation system to modify the first external data packet to generate a first internal data packet for the management system by replacing the external source MAC address with an internal source MAC address and removing the VLAN tag according to the translation mapping table; wherein the management system is operated to generate a second internal data packet with a broadcast destination IP address and an internal destination MAC address, the translation system is further operated to modify the second internal data packet to generate a second external data packet by replacing the internal destination MAC address with an external destination MAC address and adding the VLAN tag according to the translation mapping table, and the processing unit further transmits the second external data packet to the switch via the network interface.
