Deleting A Link From The Topology Database - Cisco MGX 8850 (PXM1E/PXM45) Configuration Manual

Chapter 8 Managing PNNI Nodes and PNNI Routing
Use the following procedure to delete a node from the topology database.
Physically remove the node from the network by disconnecting the cables, downing all the links between
Step 1
that node and the network, or powering down that node.
Wait for at least one hour before proceeding to Step 2. This ensures that the information for the deleted
Caution
node will not be added back into the topo database of the other nodes in the peer group if any of them
are rebooted.
Step 2 Establish a configuration session using a user name with SUPER_GP privileges or higher.
Step 3 Enter the dsptopondlist command to display all nodes in the topology node list and obtain the topology
index number of the node you want to delete.
Step 4 Enter the deltopond <topoIndex> command to delete the appropriate node from the node topology
database. Replace <topoIndex> with index number of the node you want to delete, as shown in the
following example:
M8830_CH.1.PXM.a > deltopond 1
Step 5 Enter the dsptopondlist command to verify that the appropriate node was deleted from the node
topology database.
Note If a node entry is deleted from the database, then the feeder nodes which are attached to this node are
also deleted from the database.

Deleting a Link from the Topology Database

To delete a link entry from the topology database, use the following procedure.
Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher.
Step 2 Enter the dsptopolinklist command to display all links in the link database and obtain the topology index
number of the link you want to delete.
Step 3 Enter the deltopolink <linkIndex> command to delete the appropriate link from the link topology
database. Replace <linkIndex> with the index number of the link you want to delete, as shown in the
following example:
M8830_CH.1.PXM.a > deltopolink 1
Step 4 Enter the dsptopolinklist command to verify that the appropriate link has been deleted from the link
topology database.
