Tuning Protocol Parameters

The tasks in the following subsections describe how to tune the PNNI protocol parameters that can affect

the performance of your network.

PNNI uses the Hello protocol to determine the status of neighbor nodes and PNNI topology state

elements (PTSEs) to disseminate topology database information in the ATM network.

To configure the Hello protocol parameters and PTSE significant change, perform these steps, beginning

in global configuration mode:

Switch(config)# atm router pnni

Switch(config-atm-router)#

Switch(config-atm-router)# node node-index

Switch(config-pnni-node)#
