This attribute stores the Network Administration (Nams) Identifier
associated with the Passport node. It must be unique across the
entire network of Passport nodes supporting the transport of DPN
traffic as well as all RMs and AMs in the network.
The namsId must be set when a DpnAddressPlan component is
configured on an Passport node.
The namsId is used in the accounting record, statistics record and in
time change accounting record and identifies nodes in these records.
The Nams Id is to be assigned by the network administrator.
Value 49151 indicates that no Nams Id was assigned to the module.
Changing the value of the namsId will cause the node to restart.
