Managing PNNI Route and Link Selection
Modifying a Preferred Route
Use the modpref command to change a preferred route. You can re-specify existing hops in a route or
add one or more hops to an existing route. You can also change a hop to indicate that it is the destination
node. A new destination node must have the highest hop number in the route. (See the detailed usage
guidelines for the addpref command for details.)
Enter the modpref command as follows:
8850_LA.7.PXM.a > modpref [-name <yes/no>] [-h1 {<persNodeIndex>/<portId>}]
[-h2 {<persNodeIndex>/<portId>}] ... [-h20 {<persNodeIndex>/<portId>}]
Table 6-7 describes the modpref command parameters.
-direct Change the directed route status. A directed route means the preferred
route associated with the connection is the only route the connection can
take. If the preferred route is not available, the connection is failed. Type
-direct yes to make the route identified by rteID a directed route for the
associated connection. The connection is identified by portid vpi vci.
Possible entries: yes or no
Default: no
-onPrefRte Informs the node that the connection is routed on its associated,
preferred route. The purpose is to prevent rerouting of the connection
during grooming. The possible entries are yes or no.
Before setting this the onPrefRte option to yes, enter the dspcon <portid>
<vpi> <vci> command to ensure that the connection is properly routed on
the preferred route.
Default: no
