Managing PNNI Routes
The following example sets the deroute delay to 20 seconds and uses the dsppnportloscallrel command
to verify the configuration change:
PXM1E_SJ.7.PXM.a > cnfpnportloscallrel 7:2.10:10
PXM1E_SJ.7.PXM.a > dsppnportloscallrel 7:2.10:10
Deroute Delay: 30 seconds
Call release on Los :enabled

Improving and Managing Rerouting Performance

The following sections provide some guidelines for improving and managing rerouting performance for
the following network configurations:
•
•
•
•

Pure PXM45/C Networks

To improve rerouting performance in a pure PXM45/C based network, Cisco recommends entering the
following commands on the active PXM45/C in each switch:
•
•
•
To improve rerouting over specific NNI links, enter the following PXM45 commands at both ends of
each link:
•
•
These parameters are recommended only for the PXM45/C cards and not for the PXM45, PXM45/B or
Note
PXM1E cards.

Hybrid Networks with PXM45/C and PXM45/B

If the recommended settings for a pure PXM45/C network are used in a network that contains PXM45/B
cards, the PXM45/B nodes can experience CLI lockout as a result of the volume of connections set up
by the PXM45/C cards. CLI lockout is a condition where switch response to CLI commands is very slow
because the switch is overloaded with other tasks.
For hybrid networks with PXM45/C and PXM45/B nodes, consider upgrading the PXM45/B nodes or
limit the performance of the PXM45/C nodes to that of the PXM45/B nodes.
