This holds the flags carried by the LSP. This exposes the raw one-byte flags field from the LSP header, encoding things like the overload bit and IS type bits per the IS-IS PDU format, so an admin who wants to confirm an LSP's overload status without cross-referencing ciiSysLevelOverloadState separately can read the relevant bit directly from this attributes byte. For example, finding the overload bit set within this attributes byte for a neighbor's LSP, even while that neighbor's other status objects look otherwise normal, would confirm that neighbor has declared itself overloaded and is being avoided for transit by the rest of the area.
