The value the switching system is using to represent itself as this node. This object may only be written when pnniNodeAdminStatus has the value down.

If pnniNodeLowest is true, then the default node ID takes the form defined in Section 5.3.3 for lowest level nodes, with the first octet equal to pnniNodeLevel, the second octet equal to 160, and the last 20 octets equal to pnniNodeAtmAddress.

If pnniNodeLowest is false, then the default node ID takes the form defined in Section 5.3.3 for logical group nodes, with the first octet equal to pnniNodeLevel, the next fourteen octets equal to the value of pnniNodePeerGroupId for the child node whose election as PGL causes this LGN to be instantiated, the next six octets equal to the ESI of pnniNodeAtmAddress, and the last octet equal to zero.
