30.1.5 Configuring VLAN Mapping

Bind a VLAN used for data transfer to a VLAN mapping. A single VLAN mapping can be used on multiple rings as a common definition. As many as 128 VLAN mappings can be set. Multiple VLANs can be set for a VLAN mapping by using lists.

The VLAN for data transfer used within a ring network must be the same for all nodes. However, because only VLANs for VLAN mappings specified for VLAN groups need to match, there is no need to match the VLAN mapping IDs for all nodes in a ring network.

VLAN IDs can be added to VLAN mappings already set. When the ring to which an added VLAN mapping is applied is running, the mapping is reflected immediately. Also, when deletions are applied for multiple rings, they are all reflected at the same time. If a VLAN mapping is changed during ring operation, a loop might occur.

Delete a VLAN ID from a VLAN mapping already set. If the ring to which the deleted VLAN mapping is applied is running, the deletion is reflected immediately. Also, when deletions are applied for multiple rings, they are all reflected at the same time. If a VLAN mapping is changed during ring operation, a loop might occur.
