dsppnni-path
Display PNNI Path—display the pre-computed path tables.
The dsppnni-path command displays the pr e-comput ed paths betwee n the sour ce (the curr ent nod e) and
the destination nodes. The sys tem has determined these paths to be the best or optimal paths for various
service classes according to one of three metrics. These metrics are the admini strative weight (AW), the
cell transfer delay (CTD), or the cel l delay variation (CDV). The service class that ea ch metric supports
for the purpose of routing varies. For a list of metrics and service cla sses, s ee Ta ble 5-3 . For
dsppnni-path, you must specify a combinations of routing metric and service class.
You can also specify a node i nd e x. I f you specify a node-index, the command display s th e paths from
the source node to the node whose index you specify. To see a list of node indexes, execute
dsppnni-node-list. (The dsppnni-node-list command displays network-level node indexes under the
heading “node #.”)

Syntax
dsppnni-path {aw {cbr|rtvbr|nrtvbr|ubr|abr} | ctd {cbr|rtvbr|nrtvbr} | cdv {cbr|rtbvr}}
[node-index]
Syntax Description
Note The mandatory keywords in this command do not take the usual dash that many keywords require.
If you include a dash in front of the keyword, the system rejects the command.
Note The optional node-index lets you select a specific node in the network whose path connectivity you
want to see. The local node cr eat es t h e n od e indexes (or node numbers) accord in g to th e se q ue nc e
that it discovers its neighb o rs . You can only provide it as a command p a r am eter or view it in
applicable displays. Whether or not you specify node-index, th e node indexes appear in the “node#”
column. (Note that this node index or node# is not the node index that identifies a node within the
hierarchy of a multiple-peer grou p . S ee dsppnni-node for details on the local node index.)
