The hierarchy list represents the hierarchy of peer groups as it is seen from this switch (physical node).

As described in the ATM Forum PNNI protocol, each node sees its peer group, and the peer groups that are directly above it. It doesn't see neighboring peer groups, their content or their internal information.

The output example above represents a network with 2 levels of hierarchy. Level 1 represents the lowest level, where the physical node resides. The Level 1 output displays the following:

Level scope (56)

nodeID

ATM Address

Peer group ID for the physical node

The nodeID of the Peer Group Leader (PGL) of this peer group (if it exists)

The next level in the hierarchy, the Level 2 output, displays the following :

Level scope (48)

nodeID

ATM address
