Chapter 8 Managing PNNI Nodes and PNNI Routing
Managing PNNI Routes
Modifying a Preferred Route
Use the cnfpref command to modify a preferred route. The cnfpref command lets you re-specify
existing NEs in a route, or add one or more NEs to an existing route. You can also change an NE to
indicate that it is the destination node. A new destination node must have the highest NE number in the
route. (See the detailed usage guidelines for the addpref command for details.)
Enter the cnfpref command as follows:
8850_LA.7.PXM.a > cnfpref <rteId> <neSyntax> [-dstNePos <Ne>] [-ne1 {<node>/<port>}] [-ne2
{<node>/<port>}] ... [-ne20 {<node>/<port>}]
Table 8-8 describes the cnfpref command parameters.
Table 8-8 Parameters for cnfpref Command
Parameter Description
routeid The preferred route identifier has a range of 1–65535. If a particular ID
is in use, the node rejects the command. Check the dspprefs output for
available route IDs as needed.
neSyntax Four ways of identifying the NEs exist. Use the selected form for all NEs
in the route Type one of the following keywords:
• nodeidPnportid means the node is specified by the 22-octet node ID
and the port by the PNNI logical integer pnPortId.
• nodenamePortid means the node is specified by the node name and
the port by the physical port ID. You can use node names only if the
node names were added to the network node table (in addition to the
mandatory node IDs). You can not use the physical port ID syntax if
the pxmType is provisioned as Others. (See Table 8-5.)
• nodeidPortid means the node is specified by the 22-octet node ID
and the port by the physical port ID. You can not use the physical
port ID syntax if the pxmType is provisioned as Others. (See
Table 8-5.)
• nodenamePnportid means the node is specified by the node name
and the PNNI logical port by the integer pnPortId. You can use node
names only if the node names were added to the network node table
(in addition to the mandatory node IDs).
The nodeid is the 22-octet PNNI node ID.
The Portid is the PNNI physical port ID. On a PXM1E, the format is
slot.port. On a PXM45, the format is slot:subslot.port:subport.
The Pnportid is the PNNI logical port identifier. This form of port identifier
is an integer in the range 0–4294967295.
Default: none
