by the switch using a private protocol or manually configured, and advertised using
Exterior RA IGs. Finally, the total number of different PTSEs received at this node is
displayed.
Topology hierarchy list
Use the following command to display the hierarchy list of the PNNI network:
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
