The first series of node numbers is node # 1 through node # 6 and is the list complied by the lowest level

For the switch named mpglax4, only levels 56 and 40 were configured. Therefore, the display shows the
last node name at level 40 of "mpglax4-02."

For levels above the lowest, the node index is appended to the name of the switch. See the node name
column in the display for a multi-peer group in the Example section. For the definition of a node
index, see the description of the dsppnni-node command.
