• Subport corresponds to the resource partition on the AXSM. For a UNI or NNI, this resource
partition is the same number as the logical port number (ifNum) on the AXSM. For a virtual
network-to-network interface (VNNI), the number does not directly correspond to the
For each physical port number, PNNI also generates a logical port number as an encrypted form of the
physical port number. The logical port number appears as an unformatted numerical string. For example,
a PNNI physical port ID may have the form 1:1.2:2, so the PNNI logical port number would be
16848898. Where needed, the descriptions in the PNNI command chapter define the need for this logical
port number. (This section does not define a PNNI logical port number, nor does it describe the
correspondence between an AXSM port and a PNNI logical port number.) For the correspondence
between a PNNI physical port and the port identifier on an AXSM, see
