This managed object is applicable only when Network / IPL sharing by time (9.3.2.1) or Network / IPL sharing by tag (9.3.2.2) or Network / IPL sharing by encapsulation (9.3.2.3) is supported. The object identifies the value representing the encapsulation method that is used to transport IPL frames to the Neighbor Portal System when the IPL and network link are sharing the same physical link. It consists of the 3-octet OUI or CID identifying the organization that is responsible for this encapsulation and one following octet used to identify the encapsulation method defined by that organization. Table 9-11 provides the IEEE 802.1 OUI (00-80-C2) encapsulation method encodings. A Default value of 0x00-80-C2-00 indicates that the IPL is using a separate physical or Aggregation link. A value of 1 indicates that Network / IPL sharing by time (9.3.2.1) is used. A value of 2 indicates that the encapsulation method used is the same as the one used by network frames and that Network / IPL sharing by tag (9.3.2.2) is used.
