Chapter 8 Managing PNNI Nodes and PNNI Routing
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
section earlier in this chapter.
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:
•
lowest administrative weight (minaw)
•
maximum available cell rate (maxavcr)
•
maximum cell rate configured for the link (maxcr)
•
random link selection (loadbalance)
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 >
cnfpnni-link-selection
pnportid
minaw|maxavcr|maxcr|loadbalance
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: 1:2.1:1 link selection: minaw
logical port id: 16848897
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
