Chapter11 Configuring ATM Routing and PNNI
Advanced PNNI Configuration
Example
The following example shows the PNNI complex node configuration:
Switch# show atm pnni aggregation node
PNNI nodal aggregation for local-node 2 (level=56, child PG level=60)
Complex node representation, exception threshold: 60%
Configured nodal aggregation modes (per service class):
CBR VBR-RT VBR-NRT ABR UBR

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.

Configuring PNNI Hello, Database Synchronization, and Flooding Parameters

PNNI uses the Hello protocol to determine the status of neigh bor 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:
Command Purpose
Step1 Switch(config)# atm router pnni
Switch(config-atm-router)#
Enters ATM router PNNI mode.
Step2 Switch(config-atm-router)# node node-index
Switch(config-pnni-node)#
Enters node configuration mode.
