Managing PNNI Routes

Deleting a Node from the Network Node Table

Before you can delete a node from the network node table, enter the dspnwnode <nodeId> command to
ensure that the node is not part of a preferred route.
Note You can not delete a node from the network node table if it is currently being used by a preferred route.
If the node you want to delete is not being used by a preferred route, enter the delnwnode <nodeId>
command to delete the node from the network node table. Replace <nodeId> with the 22-octet node
identifier that you set with the addnwnode command, as described in the
Node Table"

Configuring Link Selection for Parallel Links

When parallel links exist between two nodes on a route, the node closest to the originating node selects
a link based on one of the following factors:
•
•
•
•
Note The route selection process is described in the Cisco PNNI Network Planning Guide for MGX and SES
Products.
To configure the link selection method, enter the cnfpnni-link-selection command as follows:
mgx8830a.1.PXM.a >
Replace pnportid with the port ID in the format slot[:subslot].port[:subport]. (This is the same format
that appears when you display ports with the dsppnport command.) Enter one link selection method
after the port ID.
To display the link selection method, enter the dsppnni-link-selection command as follows:
mgx8830a.1.PXM.a > dsppnni-link-selection 1:2.1:1
physical port id:
logical port id:

Configuring the Maximum Bandwidth for a Link

The maximum bandwidth for a link is defined when a PNNI partition is configured for a port. For more
information, see
