Communication apparatus, communication setting method, and non-transitory storage medium

A communication setting method comprising:

• acquiring, for communicably connecting with an opposing apparatus using VLANs (Virtual Local Area Networks) on multiple communication pathways, communication addresses of the opposing apparatus and relay apparatuses located on the communication pathways;
• acquiring used VLAN-IDs already being utilized for configuring other VLANs by the opposing apparatus and the relay apparatuses located on the communication pathways;
• identifying a VLAN-ID that is not being utilized based on the used VLAN-IDs that are already being utilized for configuring other VLANs by a local apparatus, the relay apparatuses, and the opposing apparatus;
• and
• setting, using the identified VLAN-ID, settings for communicably connecting the opposing apparatus and the relay apparatuses indicated by the communication addresses on a single communication pathway using a new VLAN.

A non-transitory computer-readable storage medium that stores a program that causes a computer in a communication apparatus to execute processes, the processes comprising:

• acquiring, for communicably connecting with an opposing apparatus using VLANs (Virtual Local Area Networks) on multiple communication pathways, communication addresses of the opposing apparatus and relay apparatuses located on the communication pathways;
• acquiring used VLAN-IDs already being utilized for configuring other VLANs by the opposing apparatus and the relay apparatuses located on the communication pathways;
• identifying a VLAN-ID that is not being utilized based on the used VLAN-IDs that are already being utilized for configuring other VLANs by a local apparatus, the relay apparatuses, and the opposing apparatus;
• and
• setting, using the identified VLAN-ID, settings for communicably connecting the opposing apparatus and the relay apparatuses indicated by the communication addresses on a single communication pathway using a new VLAN.
