Advanced PNNI Configuration
Examples
The following example shows the link aggregation mode:
Switch# show atm pnni aggregation link
PNNI PGL link aggregation for local-node 2 (level=72, name=Switch.2.72)
Configured aggregation modes (per service class):
CBR VBR-RT VBR-NRT ABR UBR
~~~~~~~~~~~ ~~~~~~~~~~~ ~~~~~~~~~~~ ~~~~~~~~~~~ ~~~~~~~~~~~
aggressive best-link best-link best-link best-link
No Aggregated links for this node.
Switch#
The following example shows how to display the node aggregation mode:
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
~~~~~~~~~~~ ~~~~~~~~~~~ ~~~~~~~~~~~ ~~~~~~~~~~~ ~~~~~~~~~~~

Configuring Significant Change Thresholds
PNNI topology state elements (PTSEs) would overwhelm the network if they were transmitted every
time any parameter in the network changed. To avoid this problem, PNNI uses significant change
thresholds that control the origination of PTSEs.
Note Any change in administrative weight (AW) and cell loss ratio (CLR) is considered significant and
triggers a new PTSE.
