Chapter 8 Managing PNNI Nodes and PNNI Routing
Managing Connection Grooming
The threshold gains can be defined for all applicable ATM service types as shown in Table 8-12.
When the grooming operation evaluates a connection for rerouting, it uses just one of the three available
metrics. The chosen metric is based on the metrics configured for the connection. You can view the
configuration of connection metrics by entering the dspcon command for the connection. Connection
metrics that display -1 are not configured. In the following example, none of the three metrics are
configured.
