Abstract
An inspection device includes a memory, and a processor coupled to the memory and configured to transmit an inspection packet that includes, as a transmission destination address, a first address for which a plurality of transfer devices in a network does not learn correspondences between the first address and transfer destination devices, to the network, receive a first packet from the network, determine whether the first packet matches the inspection packet, and instruct to transmit a setting packet of which a transmission source address is set to the first address to the network.
Claims12
An inspection device comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- transmit an inspection packet that includes, as a transmission destination address, a first address for which a plurality of transfer devices in a network does not learn correspondences between the first address and transfer destination devices, to the network;
- receive a first packet from the network;
- determine whether the first packet matches the inspection packet;
- and
- instruct to transmit a setting packet of which a transmission source address is set to the first address to the network.
A packet processing device comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- acquire a first address for which a plurality of transfer devices in a network does not learn correspondences between the first address and transfer destination devices;
- generate a setting packet of which a transmission source address is set to the first address;
- transmit the setting packet to the network after an inspection packet that includes the first address as a transmission destination address is transmitted to the network;
- and
- receive the inspection packet from the network.
An inspection system comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- transmit an inspection packet that includes, as a transmission destination address, a first address for which transfer devices do not learn correspondences between the first address and transfer destination devices, to a network, the transfer devices forming the network coupled to the inspection system;
- receive a first packet from the network;
- determine whether the first packet matches the inspection packet;
- instruct to transmit a setting packet of which a transmission source address is set to the first address to the network;
- acquire the first address based on an instruction for transmitting the setting packet;
- generate the setting packet;
- transmit the setting packet to the network after the inspection packet is transmitted to the network;
- and
- receive the inspection packet from the network.
