Chapter 6 Managing PNNI Nodes and PNNI Routing
Managing PNNI Route and Link Selection
The preferred routes are specified by the addpref command. To see a list of all preferred routes and
obtain the required route index for the modpref command, use the dspprefs command. To see details
about individual preferred route, use the dsppref command.
Deleting a Preferred Route
Enter the delpref <rteId> command to delete a route. Replace <rteId> with the route identifier for the
appropriate route, in the range from 1 through 5000.
Table 6-7 modpref Command Parameters
Parameter Description
rteID The preferred route identifier has a range of 1-5000.
-name En ter yes to specify tha t the node identifier is actually the name of t he n ode.
You can see the current choice for node identifier (either by index or name) by using
the dsppref command. To identify the name or persistent index number by using the
dsptopondlist command.
Default = no
For more information on the preferred route naming conventions, see the section,
“Detailed Usage Guidelines for the addpref Command” In the “MGX 8850 and
MGX 8950 Switch Command Reference.”
-h1, -h2 ...-h20 Specifies each hop in the preferred route. Including the local node, you can define
up to 20 nodes in the preferred route.
Each hop in the preferred route is defined by a pairing of the persistent node index
and the PNNI physical port ID.
The <persNodeIndex> (persistent node index) is a namestring. You need to enter this
option only if you include the -name yes option in the modpref command.
Note If you entered modpref -name no command, or if you do not specify the
-name option in the command, then <persNodeIndex> refers to a table index
derived from the persistent topology database. Enter the dsptopondlist
command to view the table index.
For the last port ID in the route, type a “#” instead of a numeric value. This # appears
in the outputs of the display commands for preferred routes. Separate these values
by a slash and no spaces, as follows:
persNodeIndex/portid
The node must exist in the persistent topology database. Use the dsptopondlist
command to see the nodes in this database. (An alternate to using node indexes is
using node names.)
The format for portid is slot:subslot.port:subport.
