Network system, network management server, and access filter reconfiguration method |
摘要 |
Provided is a network system, comprising: a plurality of network devices; a network constructed from the plurality of network devices; and a management server managing the network. The plurality of network devices include a first network device in which a filter assigned as a target of reconfiguration is set and a second network device coupled at a lower level of the first network device. The management server obtains topology of the network from the plurality of network devices; reconfigures, by referring to the obtained network topology, the filters of the first and second network device such that a range in which a packet can be forwarded through a reconfiguring filter set in the first network device is made equal to a range in which a packet can be forwarded through the filter set in the second network device; and sets the reconfigured filters into the network devices. |
