ctVlanIdToFidMapping 1.3.6.1.4.1.52.4.1.2.16.4.4.1.5

The 12 bit Filter Database Identifier (FID) associated with the configured VLAN as specified by ctVlanVID. For devices operating in Independent VLAN Learning (IVL) mode, as specified by a value of ivl(1) for ctVlanLearningMode, each VLAN will be mapped to a FID value equal to the VLAN Id specified by ctVlanId. For devices operating in Shared VLAN Learning (SVL) mode, as specified by a value of svl(2) for ctVlanLearningMode, all VLANs will be to the same FID (1). On a device operating in SVL mode, sets to this object will have no effect. For devices operating in Shared and Independent VLAN Learning (SIVL) mode, as specified by a value of svlivl(3) for ctVlanLearningMode, one or more VLANs can be mapped to each FID. Each VLAN can only be uniquely mapped to one FID. When more than one VLAN is mapped to a single FID they will operate together under the SVL mode of operation. When a single VLAN is mapped to a FID it will operate under the IVL mode of operation. The default value for this object, while the device is svlivl(3) mode, will be equal to the VLAN Id specified by ctVlanId.
