Chapter 8 Managing PNNI Nodes and PNNI Routing
Maintaining a Persistent Network Topology for CWM
Note
Only 16 feeder entries can be stored in the topology database for each routing node. If more than 16
feeders are provisioned on one switch, there might be inconsistencies between the actual feeders and the
feeder information in the topology database.
Enter the dsptopogwndlist command to display a list of the gateway nodes in the topology database, as
shown in the following example:
M8830_CH.1.PXM.a >
dsptopogwndlist
table index: 1 node name: M8830_CH
node id:56:160:47.00918100000000001a538943.00001a538943.01
table index: 2 node name: PXM1E_SJ
node id:56:160:47.00918100000000001a533377.00001a533377.01
table index: 5 node name: M8850_SF
node id:56:160:47.009181000000000164444b61.000164444b61.01
Displaying Link Information
The network topology database contains information about the links in the peer group. When a node is
configured as gateway node, that node’s current PNNI link information is saved in the link topology
database. If a link is down when the node is configured as a gateway node, the downed link will not
appear in the topology database until it comes back up.
Feeder Shelf
The feeder’s shelf numbers, which identify the port on the feeder
itself.
Feeder Slot
The feeder’s slot number, which identify the port on the feeder
itself.
Feeder Port
The feeder’s port numbers, which identify the port on the feeder
itself.
Feeder model number
The feeder’s model number. This integer is used to differentiate
between feeder platforms.
Feeder LMI type
(whether the port is
feeder or XLMI)
Displays whether the Link Management Interface (LMI) is a
regular feeder or XLMI.
Feeder type
Identifies the feeder type.
